Can I delete my first two marriages and just skip ahead to the third?
Fraser! At 1:50 you say "the density of matter is so high, the escape velocity exceeds the speed of light." REALLY?!?! According to Einstein's theory of special relativity, published in 1905, nothing can exceed the speed of light. That speed, explained Einstein, is a fundamental constant of nature: It appears the same to all observers anywhere in space. So what's up with THAT?! :-)
Pay attention - Fraser is talking about escape velocity. He is not saying that actually matter has speed greater than c. Consequence is that nothing can escape, even the light, because of... escape velocity higher than c ;)
i wouldn't mind losing all those wrestling comments on the chalk board behind Hawking in a BH forever...
