Although to an outside observer he may appear to stretch out with the spaghetti effect, to his head and feet, because time slows closer with higher gravity, they appear to be moving at the same speed. <br /><br />Of course, an outside observer would not be able to observe anything inside the classical event horizon, but you know what I mean. :-)Rosa Rubicondiorhttps://www.blogger.com/profile/06063268216781988588noreply@blogger.comtag:blogger.com,1999:blog-7583674511519808833.post-32332367387691037152014-02-04T14:24:04.445+00:002014-02-04T14:24:04.445+00:00Maybe it's a quibble, but the only way an astr...Maybe it's a quibble, but the only way an astronaut could fail to notice a change if he fell into a black hole would be if said astronaut was a dimensionless point.<br /><br />Here's what I wrote <a href="http://bill-purkayastha.blogspot.in/2011/10/inside-black-hole.html" rel="nofollow">on the subject</a> back in 2011:<br /><br />Hollywood movies apart, no astronaut would be advised to try and dive into a black hole. Let’s suppose someone fell into one feet-first. As this intrepid (and suicidal) adventurer fell, the gravity around his feet would be many times greater than the gravity at his head, because his feet are closer to the black hole and the distance between them and his head would mean that the gravity affecting his feet is greater by the square of his height (the Inverse Square Law, again). This is true of all gravity, but most gravitational fields are so weak that it doesn’t matter. However, since the gravity well of a black hole is so strong, the difference in pull along the length of his body would stretch him out like a piece of chewing gum; as he fell into the event horizon, he’d be drawn into something resembling a thread, hundreds of kilometres long.Bill the Butcherhttps://www.blogger.com/profile/08436195659154078021noreply@blogger.com
