'Refuting Creationism - Scientists Have Found Strong Evidence of Life On Mars!

'Potential biosignatures' found in ancient Mars lake | Imperial News | Imperial College London

Scientists analysing data from NASA’s Perseverance rover have reported a tantalising discovery from Jezero Crater on Mars: rocks rich in minerals and chemical patterns that could represent potential biosignatures — the traces left behind by ancient life. The findings, published by an international team led from Imperial College London, point to the remains of an ancient lake where conditions may once have been favourable for microbial life to take hold.

The evidence comes from mudstones, clays, silica, iron-phosphate and iron-sulphide nodules, along with carbon compounds that appear to have undergone redox reactions. On Earth, such processes are often associated with biology, though the researchers are careful to stress that non-biological explanations are still possible. It will take the return of rock samples to Earth, with far more powerful laboratory techniques, before firm conclusions can be reached.

Creationism Refuted - Scientists See A Planet Being Born - No God(s) Involved



A growing baby planet photographed for first time in a ring of darkness | University of Arizona News

Astronomers led by University of Arizona’s Laird Close, alongside Leiden Observatory graduate student Richelle van Capelleveen, have directly observed a planet in the making — WISPIT 2b — nested within the rings of a protoplanetary disk around a young Sun-like star in the constellation Aquila, about 430 light-years away. The planet is confirmed to be about five times Jupiter’s mass, actively accreting gas, and clearing a prominent gap in the disk. This observation aligns almost perfectly with the long-standing scientific model of planet formation—and stands in stark contrast to the biblical narrative of instant land-mass creation, involving no orbit, disk, or extended evolutionary process.

This discovery will be depressing news for creationists, especially when contrasted with the biblical account of Earth’s creation — where magic words allegedly call a small, flat land mass into existence consisting of a few square miles of land around the Canaanite Hills, with no hint of orbiting a star or forming within a protoplanetary disk. The stark mismatch extends beyond metaphor — the actual physical process astronomers observe has no room for magic, and more importantly, aligns precisely with predictions from scientific theories of planetary formation.

The Universe Is Nothing Like The Description of it in The Bible 5

Unusual carbon dioxide-rich disk detected around young star challenges planet formation models - Stockholm University

This, the last in this series - at least for a while - is on the discovery made by the James Webb Space Telescope (JWST) of a disk rich in carbon dioxide around a young star. Apart from again highlighting the yawning gap between the Bible's child-like description of the universe and the real thing, it also showcases how, contrary to creationist conspiracy theorists’ claims that scientists are not allowed to publish anything which challenges “scientific orthodoxy,” a discovery that challenges the current consensus is openly flagged to the scientific community in peer-reviewed publications.

The problem this raises for cosmology is that, in the standard model of planetary formation, icy grains from the colder outer regions of a disk drift inward. As they cross the so-called snow lines, the ice sublimates into gas: first carbon dioxide, then closer in, water vapour. Because both species are expected to follow this process, astronomers normally expect water vapour to be at least as abundant as, if not more abundant than, carbon dioxide in the warmer inner regions. Yet in the disk surrounding a young star in the star-forming region NGC 6357, JWST found the reverse of what models predict — little or no water, but a striking abundance of carbon dioxide.

Intriguingly, the observation may also help explain another puzzle: the unusual isotopic fingerprint found in meteorites and comets. The imbalance of gases could be linked to intense radiation altering chemical pathways in the disk.

For Bible literalists, however, such details have no bearing on their imagined universe of a small, flat Earth with a dome overhead and fixed, immovable stars. There is no recognition in their text of star formation, accretion disks, or the vastness and dynamism of a changing cosmos. The Bible’s universe doesn’t even contain planetary systems.

The stamps are 2″×2″ in size and are oriented with north being up and east being left. The images are from the HST ACS, JWST NIRCam, and JWST MIRI, with the passbands as noted. Most of the very bright dropouts are either disk-like (∼40%) or compact (∼45%) in morphology in F356W, and one each is shown for the F090W, F150W and F200W dropouts. The example F115W dropouts include a disk-like object and an irregular object. Only ∼15% of the very bright dropouts have irregular morphologies. The color stamps in the last column are constructed based on the NIRCam images, using F090W + F115W + F150W as blue, F200W + F277W as green, and F356W + F410M + F444W as red.
Early galaxies — or something else? Mizzou scientists uncover mysterious objects in the universe

In this fourth article in the series contrasting the real universe with the one described in the Bible, I look at the announcement that two cosmologists from the University of Missouri have discovered about 300 objects that are brighter than they should be if they are what researchers think they are – some of the first galaxies in the early universe. If that's what they turn out to be, it will require a reassessment of what cosmologists thought they knew about the formation of galaxies.

This highlights a frequently repeated contradiction in creationist claims: on the one hand, they insist scientists are only allowed to publish papers that conform to existing consensus, so "creationist science" never gets published; on the other hand, they complain that scientists keep changing their minds and rewriting the science books, unlike the Bible which never changes. They claim this means science is unreliable and not to be trusted. Obviously, both can't be right, but that doesn't stop creationists from claiming both simultaneously.

The other problem this paper highlights is the sheer scale of the universe and the timeline involved, which make the Bible's account look laughably naïve, even childish in its simplicity.

These mystery objects, discovered by the James Webb Space Telescope, are in the order of 13–14 billion light-years in look-back time, meaning we are seeing the light that left them when the universe was only a few hundred million years old. Because the universe has been expanding ever since, their actual present-day distance is much greater — probably 25–30 billion light-years away.

This doesn’t contradict the 13.8-billion-year age of the universe: the light has only been travelling for 13 billion years, but in that time the fabric of space itself has stretched. It’s a bit like two ants on a rubber band: one ant flashes a signal when it is 13 cm away, but by the time the other ant sees it, the band has stretched so much that they are now 30 cm apart. The signal only travelled 13 cm, but the current separation is larger because of the stretching. To suggest, as creationists must, that the well-established methods of cosmological distance measurement are so wrong that they confuse a universe a few thousand years old with one tens of billions of light-years across, is to cling to absurdity.

In fact, this paper shows science at its best. The researchers are effectively saying to their colleagues: “Look, we may have found a fundamental problem that could mean we were wrong all along. Let’s investigate further and be prepared to change our minds if the evidence demands it.” Now imagine a creationist announcing that they had discovered a contradiction in the Bible that forced them to question its divine authorship, or a Discovery Institute fellow admitting to evidence that could only be explained by Darwinian evolution. Such an admission would simply never happen — and certainly never be published in a creationist outlet.

Science is reasonable uncertainty; religion is unreasonable certainty.

In this, the third entry in the series, we turn to an extraordinary image of a nebula popularly known as “The Hand of God.” Like the famous Horsehead Nebula, its nickname arises simply because it happens to resemble something faintly recognisable—in this case, the outline of a human hand. Some creationists may take comfort in that name, imagining it to mean that scientists literally see the hand of God at work in the creation of the universe.

Few things could be further from the truth. The more we learn, the clearer it becomes that the universe is not the product of spells cast by a supernatural magician, as described in the Bible, but the result of natural forces acting on a scale so vast the authors of Genesis could never have conceived it.

Without modern science—and without the stunning images produced by instruments such as the James Webb Space Telescope and the Chandra X-Ray Observatory which created this composite — we too would struggle to imagine the universe as it really is. Expecting Bronze Age pastoralists to have described it accurately would be like asking a five-year-old today to look up at the night sky and provide a scientific account of the cosmos.

What we see here is just a tiny fraction of the heavens — the area covered by a single grain of rice held at arm’s length — yet, by combining electromagnetic images at different wavelengths, scientists have rendered the nebula visible in all its grandeur.

The Universe Is Nothing Like The Description of it in The Bible 2

Using exoplanets to study dark matter | UCR News | UC Riverside

The second of five blog posts that comprehensively refute any lingering notion that Genesis is the inerrant word of a creator god, rather than the best guesses of primitive Bronze Age pastoralists, who imagined Earth as a small, flat plane beneath a solid dome. This time, the focus is on news from a University of California Riverside (UCR) team, who are using the more than 5,000 exoplanets discovered to date to investigate the mysterious phenomenon of dark matter.

Dark matter poses a challenge for science—not because its existence is in doubt, but because its nature and relationship to the standard model of particle physics remain unknown. We know it exists because it exerts gravitational effects on galaxies and other cosmic structures, yet it does not appear to interact with ordinary matter in any detectable way. What we can infer, however, is that dark matter makes up a substantial fraction of the universe’s total mass.

For science, this is a puzzle to be investigated head-on. For creationists, however, both the confirmed existence of thousands of exoplanets and the reality of dark matter are insurmountable contradictions to their Bible-based cosmology. The Genesis account insists on a tiny, flat Earth, immovably fixed at the centre, covered with a dome, with waters above and below — a description so far removed from reality that it cannot honestly be excused as metaphor, allegory, or poetic licence. It is simply wrong.

Unlike science, which welcomes such problems as opportunities to investigate and refine our understanding, religion turns a blind eye and ploughs on, muttering about “mysterious ways,” “beyond human comprehension,” or simply, “God did it!” — all while smugly pretending the issue has been solved “by faith.”

Creationists normally assume that scientists are all out to destroy their faith because they hate God and/or worship Satan, so to add to that paranoid delusion, this is the first of five blog posts about very recent discoveries in the fields of Astronomy and cosmology that illustrate the glaring contrast between the real universe and the universe described in Genesis. The Bible describes a small, flat planet fixed and immobile at the centre, covered by a solid dome, with water above and below and stars, sun and moon fixed to the dome as lamps and tiny lights that can shake lose and fall to Earth during earthquakes; the whole thing created just 6,000 - 10,000 years ago from nothing.

The first of these papers is by an international team of astronomers, led by The University of Texas at Austin’s Cosmic Frontier Center who have discovered the most distant black hole ever confirmed. It is in the galaxy CAPERS-LRD-z9 which formed 500 million years after the Big Bang. That places it 13.3 billion years into the past, when our universe was just 3% of its current age. A time line and distance completely off the Bible's scale.

This image, which combines infrared data from the James Webb Space Telescope with submillimetre observations from the Atacama Large Millimetre/submillimetre Array (ALMA), shows the doughnut-shaped torus and interconnected bubbles of dusty gas that surround the Butterfly Nebula’s central star. The torus is oriented vertically and nearly edge-on from our perspective, and it intersects with bubbles of gas enclosing the star. The bubbles appear bright red in this image, illuminated by the light from helium and neon gas. Outside the bubbles, jets traced by emission from ionised iron shoot off in opposite directions.

JWST observations of Butterfly Nebula reveal how cosmic dust is made in space - News - Cardiff University

There’s a double whammy for creationists in this new paper. Not only does it expose the Bible’s description of the Universe as laughably naïve, but it also shows how organic molecules — in the form of polycyclic aromatic hydrocarbons (PAHs) — that may have formed the basis of life on the prebiotic Earth, could have been created in deep space and later incorporated into our planet either at its formation or via impacts from space debris.

The paper, by a team of scientists led by Cardiff University, has just been published in Monthly Notices of the Royal Astronomical Society. Using data from the James Webb Space Telescope (JWST), the researchers reveal how stars generate space dust, organic material, and the fundamental building blocks from which rocky planets like Earth are formed. Their study focuses on the Butterfly Nebula (NGC 6302), a spectacular stellar remnant.

What Are PAHs?

Polycyclic aromatic hydrocarbons (PAHs) are complex organic molecules made of fused benzene rings — essentially arrangements of carbon and hydrogen in hexagonal patterns. On Earth, they are often associated with combustion (for example, in car exhaust fumes, cigarette smoke, or charred food). In space, however, they form naturally in the outflows of dying stars and in the dense molecular clouds that give rise to new stars and planetary systems.

PAHs are of great interest to astrobiologists because they are thought to be among the earliest organic compounds to have existed in the Universe. They can undergo chemical transformations to form more complex molecules, including amino acids and nucleotides, which are the essential components of life. Their presence in meteorites and interstellar dust suggests that the seeds of life were widespread long before Earth even formed.

Refuting Creationism - Oceanic Oxygenation Spured Rappid Evolution - 390 Million Years Before 'Creation Week'

How oxygen made the deep ocean home to animals, spurring rapid evolution | UW News

Another wave of reality breaks over the impervious rocks of creationist dogma, in the form of news that an international team of researchers led by the University of Washington has shown a correlation between the rapid radiation of marine vertebrates and the evolution of plants on land. As trees and other vascular plants spread, more atmospheric carbon became locked into their woody stems, reducing carbon dioxide levels. At the same time, increased photosynthesis raised atmospheric oxygen levels, which in turn oxygenated the oceans, making oxygen available in depths that had previously been anoxic.

Creationists will, of course, need to ignore the fact that this finding flatly contradicts their claims that evolution only occurs within “kinds” and that all diversification happened in a brief burst of warp-speed evolution following a genocidal global flood some 4,000 years ago. The timeline alone is utterly inconsistent with their favourite creationist fairy tale.

Scientists once believed this major oxygenation event had occurred about 500 million years ago, but the new research shows that episode was short-lived. A more significant oxygenation occurred around 390 million years ago. Initially, oxygenation would have taken place in shallow coastal regions where vertebrates first evolved. As oxygen penetrated deeper into the oceans, vertebrates followed into the newly opened niches, leading to a rapid proliferation of jawed vertebrate species — the ancestors from which terrestrial tetrapods later evolved.

The team reached their conclusions after measuring selenium isotopes in 97 sedimentary rock samples from five continents, dated between 252 and 541 million years ago. These rocks had been deposited near the edges of continental shelves, where shallow seas transition into the deep ocean. Selenium occurs naturally in several isotopic forms, and the ratios in which they were deposited depend on the level of oxygen dissolved in seawater. These isotopic signatures thus provide an indirect measure of oxygenation levels at the time the rocks were laid down.

Refuting Creationism - The Difference Between The Bible And Reality - ESA's Picture Of The Week

NGC 2835

Noteworthy nearby spiral | ESA/Hubble

Everywhere science looks, it exposes the widening gulf between the way the Bronze Age authors of the Bible imagined their tiny fragment of the cosmos and the reality we now know. Astronomy, no less than biology, geology, or palaeontology, makes clear just how limited and naïve that worldview was.

Today’s reminder of that contrast comes from the European Space Agency’s “Picture of the Week”: the so-called “nearby” spiral galaxy NGC 2835, lying a mere 35 million light-years away in the constellation Hydra, the Water Snake. In other words, the light now reaching our eyes began its journey 35 million years before the Bible’s writers imagined the universe springing into existence at the command of a magic incantation — יְהִי אוֹר (yehi or! — “Let there be light”), curiously spoken in a language there was no-one else alive to understand.

And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters. And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so. And God called the firmament Heaven. And the evening and the morning were the second day. And God said, Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so. And God called the dry land Earth; and the gathering together of the waters called he Seas: and God saw that it was good. (Genesis 1.6-10)

And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also. And God set them in the firmament of the heaven to give light upon the earth, And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.(Genesis 1.16-18)

Today’s NASA/ESA Hubble Space Telescope Picture of the Week offers a closeup of a nearby spiral galaxy. The subject is NGC 2835, which lies 35 million light-years away in the constellation Hydra (The Water Snake).

A previous Hubble image of this galaxy was released in 2020, and the NASA/ESA/CSA James Webb Space Telescope turned its gaze toward NGC 2835 in recent years as well. Do you see anything different between today’s image of NGC 2835 and the previously released versions? Overall, NGC 2835 looks quite similar in all of these images, with spiral arms dotted with young blue stars sweeping around an oval-shaped centre, where older stars reside.

This image differs from previously released images because it incorporates new data from Hubble that captures a specific wavelength of red light called H-alpha. The regions that are bright in H-alpha emission can be seen along NGC 2835’s spiral arms, where dozens of bright pink nebulae appear like flowers in bloom. Astronomers are interested in H-alpha light because it signals the presence of several different types of nebulae that arise during different stages of a star’s life. Newborn massive stars create nebulae called H II regions that are particularly brilliant sources of H-alpha light, while dying stars can leave behind supernova remnants or planetary nebulae that can also be identified by their H-alpha emission.

By using Hubble’s sensitive instruments to survey 19 nearby galaxies, researchers aim to identify more than 50 000 nebulae. These observations will help to explain how stars affect their birth neighbourhoods through intense starlight and winds.

Refuting Creationism - More On What The Bible's Authors Got Badly Wrong


A sea monster and a Tarantula ESA/Hubble

The enduring mystery is why, when they can read the first few verses of the Bible and compare it to what science reveals about the universe, or planet and the life on it, do so many people still insist it is inerrant historical and scientific truths reveal by an inerrant, omniscience creator god?

There must be some deep psychological need to believe that absurdity to perform the necessary mental gymnastics required to dismiss the science and stick with the evidence free superstitions that the science overthrows, which can only be guessed at? A personal stake, as with the priests and grifters who wring a living out of their credulous followers, maybe? A justification for holding otherwise unacceptable prejudices for which an excuse can be found in the Bible, with careful scrutiny and maybe changing the meanings of a few words here and there, or by applying the brutal tribal social norms that the Bible prescribes? Whatever the cause, the self-delusion needed to retain belief against the deluge of counter-evidence, often caries kudos in religious societies such as in America's 'Bible Belt' states and inner city ghettos where admitting to doubt or even hinting at accepting the science can carry a heavy social penalty.

So, the tidal wave of scientific evidence keeps breaking on the rocks of ignorant stupidity reinforced by sea wall of social coercive control and psychological fear akin to an acute anxiety disorder or theophobic psychosis.

A scene from a star-forming factory shines in this NASA/ESA Hubble Space Telescope Picture of the Week. This Hubble picture captures incredible details in the dusty clouds in a star-forming region called the Tarantula Nebula. What’s possibly the most amazing aspect of this detailed image is that this nebula isn’t even in our galaxy. Instead, it’s in the Large Magellanic Cloud, a dwarf galaxy that is located about 160 000 light-years away in the constellations Dorado and Mensa.

The Large Magellanic Cloud is the largest of the dozens of small satellite galaxies that orbit the Milky Way. The Tarantula Nebula is the largest and brightest star-forming region not just in the Large Magellanic Cloud, but in the entire group of nearby galaxies to which the Milky Way belongs.

The Tarantula Nebula is home to the most massive stars known, some of which are roughly 200 times as massive as our Sun. The scene pictured here is located away from the centre of the nebula, where there is a super star cluster called R136, but very close to a rare type of star called a Wolf–Rayet star. Wolf–Rayet stars are massive stars that have lost their outer shell of hydrogen and are extremely hot and luminous, powering dense and furious stellar winds.

This nebula is a frequent target for Hubble, whose multiwavelength capabilities are critical for capturing sculptural details in the nebula’s dusty clouds. The data used to create this image come from an observing programme called Scylla, named for a multi-headed sea monster from the Greek myth of Ulysses. The Scylla programme was designed to complement another Hubble observing programme called ULLYSSES (Ultraviolet Legacy Library of Young Stars as Essential Standards). ULLYSSES targets massive young stars in the Small and Large Magellanic Clouds, while Scylla investigates the structures of gas and dust that surround these stars.

Refuting Creationism - Just How Wrong Could The Bible's Authors Be?

The Cosmic Horseshoe gravitational lens.

'Most massive black hole ever discovered' is detected | The Royal Astronomical Society

The authors of Genesis got so much so badly wrong that it’s difficult to find anything they got right — but the hardest place to find even a sliver of accuracy is their description of the universe. With their naïve attempt to explain the existence of different kinds of animals, they at least recognised that there were different species. Their notion of magical creation out of nothing, without ancestry, was of course laughably wrong, but at least they knew there were distinct organisms requiring explanation.

By contrast, in their picture of the cosmos — centred on a small, flat world with a solid dome (the “firmament”) over it—about the only things they got right were the existence of Earth, the Sun and Moon, and “the stars”. Everything else was subsumed into that one word: “stars”, a bucket that included the visible planets, distant suns, and entire galaxies, all imagined as lights fixed to the dome, with the Sun and Moon set within it.

In short, almost everything in that description is wrong—not just what things are, but where they are. They spoke about light, but knew nothing of its nature. That they noticed that light comes from luminous bodies is probably the only thing they got right.

Black Holes: Nature’s Most Extreme Objects. A black hole is a region of spacetime where gravity is so intense that nothing—not even light—can escape. They form when a massive star collapses under its own gravity or through the merger of smaller black holes.

Event Horizon

The vent horizon is the “point of no return” surrounding a black hole. Once anything crosses it, escape is impossible. From outside, the event horizon appears as a dark sphere; it’s not a physical surface but a boundary defined by relativity.

Singularity

At the very centre, according to general relativity, lies a singularity — a point where density and spacetime curvature become infinite, and the known laws of physics break down. In reality, quantum effects are expected to smooth out this infinity, but a complete theory of quantum gravity is needed to describe it properly.

Relativity vs Quantum Physics

Black holes are unique because they combine two regimes of physics:
  • Einstein’s general relativity describes how they warp spacetime.
  • Quantum mechanics governs the behaviour of particles and energy at extremely small scales.

The crossover between these domains lies deep inside the black hole, in a region near the singularity sometimes called the quantum gravity zone, where spacetime curvature reaches the Planck scale and neither theory works alone. This is not the event horizon, as is sometimes said; the event horizon is still very much part of the Relativity domain.
The Firewall Hypothesis

Stephen Hawking and others noted a paradox: quantum theory predicts that information cannot be destroyed, yet anything crossing an event horizon seems lost forever. One proposed resolution is the firewall hypothesis: instead of passing smoothly through, anything hitting the horizon would be incinerated by a burst of high-energy radiation. This “firewall” would break relativity’s expectation that crossing the horizon is uneventful (for a large black hole) but would preserve quantum theory’s rules.
Open Questions
  • Does the singularity really exist, or is it replaced by something else in a quantum theory of gravity?
  • Do firewalls exist, or is there a different resolution to the black hole information paradox?
  • Can Hawking radiation—tiny energy leaks predicted by quantum field theory—eventually cause black holes to evaporate completely?

Black holes remain one of physics’ most powerful testing grounds, where the deepest laws of nature are pushed to their limits.
And of course, they could have known nothing about black holes, or about the relationship between mass and gravity that explains them and governs the motions of the “stars”.

A point I’ve made here before — worth making again — is that we can be certain the Bible was not written by a creator god by seeing how much of it is flatly wrong. Much of it can’t even be rescued as meaningful metaphor or allegory—the standard apologetic for obvious falsehoods. It is simply, unarguably, and unambiguously wrong on multiple levels.

If a creator god had written it as a vital message to humankind, why did it not include anything unknown at the time in unmistakable terms, as proof of divine authorship and omniscience? Why, for example, did it not tell us about atoms, germs, or galaxies; that Earth is an oblate spheroid orbiting the Sun along with other planets; or explain the relationship between mass and gravity and why black holes exist?

Why not? Because the authors of the Bible were ignorant of these things. They were not creator gods, but ancient Near Eastern writers doing their best to invent plausible narratives within their cultural preconceptions — of a spirit-filled world that ran on magic — when everything they knew lay within a few days’ walk of home in the hills of Canaan.

So, compare their description of the universe as they imagined it with what science now shows us: in this case, an ultramassive black hole revealed by how its gravity bends light from a background galaxy into an “Einstein ring”, a phenomenon predicted by Einstein’s general theory of relativity.

The description comes from the Royal Astronomical Society news release and the open-access paper in Monthly Notices of the Royal Astronomical Society.

First, let's see how the Bible's author described the entire universe as they saw it without the benefit of scientific instruments or theoretical physics:

And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters. And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so. And God called the firmament Heaven. And the evening and the morning were the second day. And God said, Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so. And God called the dry land Earth; and the gathering together of the waters called he Seas: and God saw that it was good. (Genesis 1.6-10)

And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also. And God set them in the firmament of the heaven to give light upon the earth, And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.(Genesis 1.16-18)

Now compare that to this image of a tiny fragment of it that astronomers at the Royal Astronomical Society have just released. It shows the gravity lensing effect and the resulting Einstein ring. Ber in mind that this is a tiny fragment of the universe that would be entirely hidden by a grain of rice held between the thumb and forefinger of your outstretched arm. There is absolutely nothing to compare it with in the Bible, obviously.
'Most massive black hole ever discovered' is detected
Astronomers have discovered potentially the most massive black hole ever detected.

The cosmic behemoth is close to the theoretical upper limit of what is possible in the universe and is 10,000 times heavier than the black hole at the centre of our own Milky Way galaxy.

It exists in one of the most massive galaxies ever observed – the Cosmic Horseshoe – which is so big it distorts spacetime and warps the passing light of a background galaxy into a giant horseshoe-shaped Einstein ring.

Such is the enormousness of the ultramassive black hole’s size, it equates to 36 billion solar masses, according to a new paper published today in Monthly Notices of the Royal Astronomical Society.

It is thought that every galaxy in the universe has a supermassive black hole at its centre and that bigger galaxies host bigger ones, known as ultramassive black holes.

This is amongst the top 10 most massive black holes ever discovered, and quite possibly the most massive. Most of the other black hole mass measurements are indirect and have quite large uncertainties, so we really don't know for sure which is biggest. However, we’ve got much more certainty about the mass of this black hole thanks to our new method.

Researchers detected the Cosmic Horseshoe black hole using a combination of gravitational lensing and stellar kinematics (the study of the motion of stars within galaxies and the speed and way they move around black holes).

The latter is seen as the gold standard for measuring black hole masses, but doesn't really work outside of the very nearby universe because galaxies appear too small on the sky to resolve the region where a supermassive or ultramassive black hole lies.

[Adding in gravitational lensing helped the team] push much further out into the universe. We detected the effect of the black hole in two ways – it is altering the path that light takes as it travels past the black hole and it is causing the stars in the inner regions of its host galaxy to move extremely quickly (almost 400 km/s). By combining these two measurements we can be completely confident that the black hole is real.

This discovery was made for a 'dormant' black hole – one that isn’t actively accreting material at the time of observation. Its detection relied purely on its immense gravitational pull and the effect it has on its surroundings. What is particularly exciting is that this method allows us to detect and measure the mass of these hidden ultramassive black holes across the universe, even when they are completely silent.

The Cosmic Horseshoe black hole is located a long way away from Earth, at a distance of some 5 billion light-years.

Typically, for such remote systems, black hole mass measurements are only possible when the black hole is active. But those accretion-based estimates often come with significant uncertainties. Our approach, combining strong lensing with stellar dynamics, offers a more direct and robust measurement, even for these distant systems.

The discovery is significant because it will help astronomers understand the connection between supermassive black holes and their host galaxies.

We think the size of both is intimately linked, because when galaxies grow they can funnel matter down onto the central black hole. Some of this matter grows the black hole but lots of it shines away in an incredibly bright source called a quasar. These quasars dump huge amounts of energy into their host galaxies, which stops gas clouds condensing into new stars.

Professor Thomas Collett.

Our own galaxy, the Milky Way, hosts a 4 million solar mass black hole. Currently it's not growing fast enough to blast out energy as a quasar but we know it has done in the past, and it may will do again in the future.

The Andromeda Galaxy and our Milky Way are moving together and are expected to merge in about 4.5 billion years, which is the most likely time for our supermassive black hole to become a quasar once again, the researchers say.

An interesting feature of the Cosmic Horseshoe system is that the host galaxy is a so-called fossil group.

Fossil groups are the end state of the most massive gravitationally bound structures in the universe, arising when they have collapsed down to a single extremely massive galaxy, with no bright companions.

It is likely that all of the supermassive black holes that were originally in the companion galaxies have also now merged to form the ultramassive black hole that we have detected. So we're seeing the end state of galaxy formation and the end state of black hole formation.

Professor Thomas Collett.

The discovery of the Cosmic Horseshoe black hole was somewhat of a serendipitous discovery. It came about as the researchers were studying the galaxy’s dark matter distribution in an attempt to learn more about the mysterious hypothetical substance.

Now that they’ve realised their new method works for black holes, they hope to use data from the European Space Agency’s Euclid space telescope to detect more supermassive black holes and their hosts to help understand how black holes stop galaxies forming stars.

ABSTRACT
Supermassive black holes (SMBHs) are found at the centre of every massive galaxy, with their masses tightly connected to their host galaxies through a co-evolution over cosmic time. For massive ellipticals, the SMBH mass (\(\small ⁠M_\text{BH}\)⁠) strongly correlates with the host central stellar velocity dispersion (⁠\(\sigma_e\)⁠), via the relation. However, SMBH mass measurements have traditionally relied on central stellar dynamics in nearby galaxies (⁠\(\small z \lt 0.1\)⁠), limiting our ability to explore the SMBHs across cosmic time. In this work, we present a self-consistent analysis combining 2D stellar dynamics and lens modelling of the Cosmic Horseshoe gravitational lens system (⁠\(z_l = 0.44\)⁠), one of the most massive lens galaxies ever observed. Using MUSE integral-field spectroscopy and high-resolution Hubble Space Telescope imaging, we simultaneously model the radial arc – sensible to the inner mass structure – with host stellar kinematics to constrain the galaxy’s central mass distribution and SMBH mass. Bayesian model comparison yields a \(\small 5\sigma\) detection of an ultramassive black hole with \(\small \log _{10}(M_\text{BH}/{\rm M}_{\odot }) = 10.56^{+0.07}_{-0.08} \pm (0.12)^\text{sys}\)⁠, consistent across various systematic tests. Our findings place the Cosmic Horseshoe \(\small 1.5\sigma\) above the \(\small M_\text{BH}-\sigma_e\) relation, supporting an emerging trend observed in brightest cluster galaxies and other massive galaxies, which suggests a steeper \(\small M_\text{BH}-\sigma_e\) relationship at the highest masses, potentially driven by a different co-evolution of SMBHs and their host galaxies. Future surveys will uncover more radial arcs, enabling the detection of SMBHs over a broader redshift and mass range. These discoveries will further refine our understanding of the \(\small M_\text{BH}-\sigma_e\) relation and its evolution across cosmic time.

1 INTRODUCTION
Most massive galaxies are believed to host a supermassive black hole (SMBH) at their centre. More importantly, host galaxies and their SMBHs exhibit clear scaling relations, pointing to a co-evolution between the galaxy and the SMBH (Kormendy & Ho 2013). The SMBH mass (⁠\(\small M_{\text{BH}\)⁠) has been shown to correlate with various galaxy properties, such as the bulge luminosity (e.g. Magorrian et al. 1998; Marconi & Hunt 2003; Gültekin et al. 2009), stellar bulge mass (e.g. Laor 2001; McLure & Dunlop 2002), dark matter (DM) halo mass (e.g. Marasco et al. 2021; Powell et al. 2022), number of host’s globular clusters (e.g. Burkert & Tremaine 2010; Harris, Poole & Harris 2014), and stellar velocity dispersion (e.g. Gebhardt et al. 2000; Beifiori et al. 2009.1). Notably, the \(\small M_\text{BH}-\sigma_e\) relation, which links SMBH mass to the effective stellar velocity dispersion of the host (⁠\(\small \sigma_e\)⁠), remains tight across various morphological types and SMBH masses (van den Bosch 2016). None the less, when SMBHs accrete mass from their neighbourhoods, they can act as active galactic nuclei (AGNs), injecting energy in the surrounding gas in a form of feedback. This feedback can be either positive, triggering star formation (Ishibashi & Fabian 2012; Silk 2013.1; Riffel et al. 2024), or negative quenching galaxy growth (e.g. Hopkins et al. 2006; Dubois et al. 2013.2; Costa-Souza et al. 2024.1).

It is expected that the most massive galaxies in the Universe, such as brightest cluster galaxies (BCGs), host the most massive SMBHs. Indeed, so-called ultramassive black holes (UMBHs; \(\small M_\text{BH} \ge 10^{10}M_\odot\)⁠) have been found in such systems (e.g. Hlavacek-Larrondo et al. 2012.1). Most of these UMBHs have been measured through spatially resolved dynamical modelling of stars and/or gas. For instance, the UMBH in Holm 15A at \(\small z=0.055\) \(\small M_\text{BH} = (4.0 \pm 0.80) \times 10^{10}M_\odot\) (⁠⁠; Mehrgan et al. 2019) and the UMBH in NGC 4889 at \(\small z = 0.021\) (⁠\(\small M_\text{BH} = (2.1 \pm 1.6) \times 10^{10}M_\odot\)⁠; McConnell et al. 2012.2) were both determined using stellar dynamical modelling. However, despite the success of this technique in yielding hundreds of SMBH mass measurements, the requirement for high-quality spatially resolved spectroscopy poses significant challenges for studies at increasing redshift (see e.g. Kormendy & Ho 2013, Suplemental Material S1).

None the less, the significance of these UMBHs lies in the fact that many of them deviate from the standard linear \(\small M_\text{BH} - \sigma_e\) relation (e.g. Kormendy & Ho 2013; den Bosch 2016). This suggests either a distinct evolutionary mechanism governing the growth of the largest galaxies and their SMBHs (McConnell et al. 2011), leading to a significantly steeper relation (Bogdán et al. 2018), or a potential decoupling between the SMBH and host galaxy co-evolution. Populating the high-mass end of the \(\small M_\text{BH} - \sigma_e\) relation, particularly through direct \(\small M_\text{BH}\) measurements, could help resolve this ongoing puzzle.

Recently, Nightingale et al. (2023), by modelling the gravitationally lensed radial image near the the Abell 1201 BCG (⁠\(\small z=0.169\)⁠), was able to measure the mass of its dormant SMBH as \(\small M_\text{BH} = (3.27 \pm 2.12) \times 10^{10}M_\odot\)⁠, therefore an UMBH. This provides a complementary approach to other high-z probes of SMBH mass, such as reverberation mapping (Blandford & McKee 1982; Bentz & Katz 2015) and AGN spectral fitting (Shen 2013.3). Unlike these methods, which require active accretion and depend on local Universe calibrations, the lensing technique offers a direct measurement independent of the SMBH’s accretion state.

In this paper, we analyse the Cosmic Horseshoe gravitational lens system (Belokurov et al. 2007), where the lens galaxy is one of the most massive strong gravitational lenses known to date. The lens galaxy is an early-type galaxy (ETG) at redshift \(\small z_i = 0.44\)⁠, possibly part of a fossil group (Ponman et al. 1994), and is notable for lensing one of its sources into a nearly complete Einstein ring (the Horseshoe). Additionally, a second multiply imaged source forms a radial arc near the centre of the lens galaxy. Due to the radial image formed very close to the centre, the inner DM distribution of the Cosmic Horseshoe can be studied in detail, as done by Schuldt et al. (2019.1). By simultaneously modelling stellar kinematics from long-slit spectroscopy and the positions of the lensed sources, Schuldt et al. (2019.1) found that the DM halo is consistent with a Navarro–Frenk–White (NFW; Navarro, Frenk & White 1997) profile, with the DM fraction within the effective radius (⁠\(\small R_e\)⁠) estimated to be between 60 per cent and 70 per cent. Moreover, their models include a point mass at the galaxy’s centre, reaching values around \(\small \sim 10^{10} M_\odot\)⁠, which could represent an SMBH; however, they did not pursue further investigations into this possibility. Using new integral-field spectroscopic data from the Multi Unit Spectroscopic Explorer (MUSE) and imaging from the Hubble Space Telescope (HST), we conducted a systematic modelling of the Cosmic Horseshoe system to reassess the evidence for an SMBH at the heart of the lens galaxy. We performed a self-consistent analysis of both strong gravitational lensing (SGL) and stellar dynamics, which demonstrated that the presence of an SMBH is necessary to fit both data sets simultaneously. This paper is structured as follows: In Section 2, we present the HST imaging data and MUSE observations, along with the kinematic maps used for the dynamical modelling. Section 3 briefly summarizes the lensing and dynamical modelling techniques, including the multiple-lens-plane formalism, the approximations adopted in this work, and the mass profile parametrization. In Section 4, we present the results from our fiducial model and alternatives models, which we use to address the systematics on the SMBH mass. In Section 5 we discuss our results and present other astrophysical implications. Finally, we summarize and conclude in Section 6. Unless otherwise, all parameter estimates are derived from the final sampling chain, with reported values representing the median of each parameter’s one-dimensional marginalized posterior distribution, with uncertainties corresponding to the \(\small 16^\text{th}\) and \(\small 84^\text{th}\) percentiles. Furthermore, throughout this paper, we adopt the cosmological parameters consistent with Planck Collaboration XIII (2016.1): \(\small \Omega _{\Lambda ,0} = 0.6911\)⁠, \(\small \Omega _{\text{m},0} = 0.3089\)⁠, \(\small \Omega _{\text{b},0} = 0.0486\)⁠, and \(\small H_0 = 67.74\) \(\small \text{km}\ \text{s}^{-1}\ \text{Mpc}^\text{-1}\).

The discovery and analysis of black holes, and phenomena such as Einstein rings, would have been utterly incomprehensible to the authors of the Bible. These were people with no concept of galaxies, the vastness of the universe, or even that Earth is a sphere orbiting the Sun. Their worldview was of a flat Earth covered by a solid dome, with the Sun, Moon, and “stars” fixed to it. The very idea of light being bent by gravity, or of objects so massive that even light cannot escape, would have been as far beyond their imagination as quantum mechanics itself.

When we compare their primitive cosmology with what modern science reveals—billions of galaxies, relativistic spacetime, the quantum-scale behaviour of matter, and black holes bending light into perfect circles—the contrast could not be more stark. The biblical description is not merely simplified; it is wrong on almost every measurable level. It has Earth at the centre, the stars as small lights, and the sky as a hard surface holding back water. Science, by contrast, uncovers a cosmos governed by consistent natural laws, tested and confirmed through observation and mathematics.

This is compelling evidence that an omniscient creator god did not write the Bible. If it had done, it could have contained truths about the nature of the cosmos that were unknown at the time, expressed in terms clear enough to be recognisable today—atoms, germs, the vastness of space, or even the basic structure of the solar system. Instead, what we find are the assumptions of scientifically illiterate Bronze Age people, drawing on local myths and imagination. The difference between their errors and the precision of modern astrophysics is not a matter of interpretation—it is a matter of fact.

This artist’s impression shows the planet-forming disc around the star V883 Orionis. In the outermost part of the disc volatile gases are frozen out as ice, which contains complex organic molecules. An outburst of energy from the star heats the inner disc to a temperature that evaporates the ice and releases the complex molecules, enabling astronomers to detect it. The inset image shows the chemical structure of complex organic molecules detected and presumed in the protoplanetary disc (from left to right): propionitrile (ethyl cyanide), glycolonitrile, alanine, glycine, ethylene glycol, acetonitrile (methyl cyanide).

The evolution of life may have its origins in outer space

If you listen to creationists, you might be persuaded to believe that the formation of inorganic chemicals—often deliberately conflated with 'life' to evoke an emotional reaction—is, for all practical purposes, impossible without the intervention of a supernatural intelligence. This is, of course, nothing more than the familiar creationist fallback: the god of the gaps argument, coupled with a false dichotomy, and dressed up with a spurious veneer of mathematical ‘proof’.

But this tactic suffered yet another fatal blow recently with the publication of a study led by Abubakar Fadul of the Max Planck Institute for Astronomy (MPIA), which reported the discovery of organic molecules in the protoplanetary disc surrounding the young star V883 Orionis. This finding provides compelling evidence that the formation of prebiotic molecules can begin even before planets form—suggesting that Earth may have developed with a complement of organic compounds already present in the accretion disc from which it emerged.

An alternative, but equally plausible, hypothesis is that these molecules could have been delivered by meteorites or other interplanetary bodies.

Creationism Refuted - Don't Laugh At the Bible's Authors, They Were Only Doing Their Best!

NGC 3285B (137 million lightyears from Earth)

NGC 3285B

A spiral galaxy with a disc made up of several swirling arms. Patchy blue clouds of gas are speckled over the disc, where stars are forming and lighting up the gas around them. The core of the galaxy is large and shines brightly gold, while the spiral arms are a paler and faint reddish colour. Neighbouring galaxies - from small, elongated spots to larger swirling spirals - can be seen across the black background.

Take a grain of rice and hold it between your thumb and forefinger at arm’s length while looking up at the night sky. The patch of sky hidden behind that tiny grain of rice probably contains thousands of galaxies—each with around half a trillion stars. Some of these stars are ancient, nearing the end of their tens-of-millions-of-years lifespans; others are just beginning to form from clouds of gas and debris left behind by older stars that exploded as supernovae.

What lies behind that grain of rice is a tiny fragment of a dynamic, evolving, ever-changing, and expanding universe. A universe of which our ancient prophets were completely unaware as they crafted imaginative descriptions of its origins—descriptions written just a few thousand years ago that portrayed it as a small, unchanging cosmos, with a flat Earth at the centre covered by a dome.

But let’s not be too hard on them. As they stood in their Canaanite pastures, the Earth must indeed have looked flat and small, and the sky would have seemed like the roof of a great tent, adorned with tiny lights and with the sun and moon suspended from it. To them, the Earth appeared fixed and immobile while the dome overhead turned slowly, or perhaps invisible spirits moved the lights across the heavens each night. They didn’t know where the sun went after sunset and imagined the moon might hide in a deep valley during the day.

Creationism Refuted - A Planet Is Born - And The Bible Tale Looks Even More Absurd

It takes a special form of self-deluding immunity to facts and reason for creationists to cling to the absurd belief that the Bible’s description of a small universe formed *ex nihilo* in a few days — by nothing more than a few magic words spoken in a language no one was alive to understand — could possibly reflect reality.

Meanwhile, science continues to produce evidence for a very old, immense universe that is constantly changing and evolving, where new stars and planetary systems are being observed as they form. Many of these systems lie so far away that the light from them has taken billions of years to reach us — in stark contrast to the few thousand years allowed by the Biblical narrative.

As I’ve previously explained on this blog, modern astronomy and the wealth of evidence it provides shows that the Biblical account is not merely inaccurate — it is irredeemably wrong. It can’t even be salvaged as metaphor or allegory. It is exactly as wrong as one would expect from people who believed the Earth was a small, flat disc with a dome over it, and that life was created out of soil, fully formed, just a few thousand years ago.

Today, we have yet more evidence that utterly refutes the Bible’s creation myth — and this time, it doesn’t come from events billions of years ago, but from a mere 440 light-years away. That means the light we’re seeing now set off on its journey in 1585 — the same year Sir Walter Raleigh attempted to found the ill-fated Roanoke Colony in North America, and the Anglo-Spanish War broke out.

Astronomers at the European Southern Observatory (ESO), using the Very Large Telescope (VLT), have observed a giant planet forming within the accretion disk of a young star — exactly as the modern theory of planetary formation predicts. In other words, the universe is still forming and evolving, in complete contradiction to the static, one-time-only creation described in Genesis.

Abiogenesis News - Not Random Chance Or Divine Magic But Natural Selection

One fallacy with which anyone who has tried to engage a creationist in debate will soon become familiar is the false dichotomy. This is where a creationist attempts to make a "god of the gaps" argument appear logical by presenting it as a binary choice between something so simplistic or absurd that no serious scientist would argue for it—and "God did it!" In doing so, they ignore the actual scientific explanations and exclude all other plausible natural mechanisms.

A classic example of this is the argument that abiogenesis—often deliberately misrepresented as the spontaneous assembly of a complex, living cell from inorganic materials—is far too improbable to have occurred by chance alone, and therefore must have required a supernatural intelligence. In their minds, the very existence of complex life is "proof" of their particular deity.

This line of reasoning overlooks the crucial role played by natural processes, such as chemistry and physics, and what amounts to an evolutionary process at the molecular level. In such a process, chemical pathways that are more efficient at producing copies of themselves are naturally favoured, leading over time to increased refinement and complexity. For instance, why was the five-carbon sugar ribose selected as the backbone sugar in RNA?

This is the question that two researchers at the Scripps Research Institute have tackled. They demonstrated that ribose is far more efficiently phosphorylated than its alternatives, forming the chemical basis of nucleotides—the building blocks of RNA (and later DNA). This efficiency gave ribose a natural advantage, allowing it to "win" the competition against other sugars.

Their findings show that the emergence of ribose was not the result of random chance, but the predictable outcome of the underlying chemistry and physics. The study has been published in the international edition of the journal of the German Chemical Society, Angewandte Chemie.

The work is also summarised in accessible terms in a Scripps Research press release.

One of the more dishonest tactics employed by creationist grifter Ken Ham is his infamous question: "Were you there?" As though the only valid form of evidence is eye-witness testimony. The implication is clear—if you didn’t personally observe a species evolving, then you have no grounds to claim that evolution occurred. And by extension, Ham suggests that his own creationist claims are equally valid and deserve the same consideration as scientific explanations, despite the fact that he wasn't there either.

Of course, this deliberately ignores the many well-documented instances of observed evolution and the overwhelming fossil evidence showing gradual transitions over time.

He applies the same fallacious reasoning to cosmology, dismissing scientific accounts of Earth’s and the solar system’s origins on the grounds that no one was there to witness them. As though this somehow makes the biblical Bronze Age myth—a magical spontaneous assembly in response to divine incantation—equally plausible.

In a typically cynical move, Ham teaches children to parrot this question as a way to shut down scientific discussion. Rather than encouraging curiosity with the far more constructive question, "How do you know that?" — a gateway to learning about observation, extrapolation, and logical reasoning — he arms them with a slogan designed to obstruct inquiry and preserve ignorance, while making them feel smugly superior to the scientists having exposed the 'flaw' in their reasoning.

But now, thanks to cutting-edge astronomical research, science has delivered something akin to “being there” at the birth of a planet.

An international team of researchers, using the ALMA telescope (operated in part by the European Southern Observatory) and the James Webb Space Telescope, have observed what appears to be the formation of an Earth-like planet in the accretion disk of a young star. This is direct evidence supporting the scientific model of planetary formation — the very process that explains the origins of Earth and the solar system.

Predictably, this discovery will require some creative misrepresentation from creationists to dismiss it. No doubt we’ll hear claims that it’s not really the same process that formed Earth, or that it doesn’t disprove Genesis — because defending ancient mythology apparently requires ignoring any modern evidence that makes it look absurdly naive.

Refuting Creationism - The 'Abiogenesis Gap' Just Got a Little Bit Smaller

Creationism's ever-shrinking, gap-shaped creator god has just lost a little more ground. New research suggests that the formation of basic organic molecules may have been far easier under early Earth conditions than previously thought. Remarkably, scientists have found that urea—a key organic compound—can form spontaneously from ammonia and carbon dioxide on the surface of water droplets. This process requires no catalysts, no high pressure or heat, and consumes minimal energy.

Although vitalism was refuted as early as 1828 — decades before Darwin — creationists still claim that life cannot arise from non-living matter. Yet they quickly retreat when asked how dead food becomes living tissue, or what exactly they mean by ‘life’: a substance, a process, or some kind of magical force. In reality, life is a set of chemical processes, and at its core, it’s about managing entropy—using energy to maintain order against the natural drift toward disorder.

The discovery was made by researchers at Eidgenössische Technische Hochschule (ETH) Zürich in collaboration with colleagues from Auburn University in Alabama, USA. Their findings have just been published in Science.
