It tells your story and how the stuff you are made of came to be and found itself on a tiny speck in the cosmos where the conditions were right to make more stuff stuff that could reproduce itself.
It explains why, 3.8 million years later, you can look at the cosmos and wonder how it all happened.
This book tries to answer that question, not in the technical terms one scientist would use when talking to another but in terms that should be understandable to anyone who wants to know this amazing story - the story of you!
Like all good books it should leave you feeling satisfied but wanting more. Above all, it should leave you feeling both very special and very humble.
From Chapter 1 'Something for Nothing'
The singularity cannot have had a cause because there was nothing to cause it. It could not have exist anywhere because there was nowhere for it to exist. It cannot have had a before because there was no time for it to have been in. It did not exist in space or time because there was no space or time for it to exist in.
For all practical purposes, it did not exist. It is zero; nothing; nada; not.
And yet this nothing gave birth to the entire Universe!
