Sadly people on social media are saying he will regret not believing in god now. Errr no he won’t regret anything.
You say that, but...

The astronaut stuff is general relativity, which is the more complete description of space-time. Special relativity is a, believe it or not, a simple case. Both due mainly to Einstein, who didn’t get a Nobel Prize for either (from memory, his NP was for the explanation of the photoelectric effect). I did a third year course in General Relativity, which was truly a head feck and the fiercest maths I’ve ever had to contemplate.I spent the morning listening to various professors talking about crazy physics stuff on the radio this morning.
Apparently if an astronaut was entering a black hole, their perception of time would speed up so fast that before they crossed the event horizon they would witness the conclusion of the universe, whilst observers on earth would stay in their time and never even see the astronaut enter the black hole.
The other thing they explained was to do with the speed of light. Nothing is faster than light, so if you had two cars moving away from each other both traveling at the speed of light, and a passenger shined a torch at the other car, they would see the light from the torch even though they were traveling away from each other at what would appear to be twice the speed of light. This is because nothing can travel fast than light so space and time would have to change to accommodate this.
I don’t understand it, but it sounded very impressive.
You see?Hawkins was a major player in attempting to understand the thermodynamics of black holes, which is where I check out.
I was disappointed with Prof Hawkins when he abandoned his roots and started talking with an American accent.
