- What does this tell us about whether it is possible to fall in a black hole, and come out in another universe. The existence of alternative histories with black holes, suggests this might be possible. The hole would need to be large, and if it was rotating, it might have a passage to another universe.But you couldn't come back to our universe. So, although I'm keen on space flight, I'm not going to try that.
I just finished reading this lecture, and I have to admit that I think it would be pretty interesting to fall into a rotating black hole and see what there was to see on the other side. Although I've read elsewhere that falling into a black hole would basically pulverise you. What do you have to say about this lecture?
@swedishbadgergirl and reddirecphthoo* here's what my Google-fu led me since I had mentioned I was going to start looking into more of NDT's lectures -
This will probably interest you guys a lot too. It's an hour long lecture so it's technical enough to give great insight yet easy to follow.
I heard something similar to this (iirc) on Through The Wormhole which is what got me into cosmology and what not, the episode on black holes is actually what sealed the deal for me. I have to also toss it out there that the one thing I really enjoy 'bout NDT is how accessible he makes everything. (see the recently ended Cosmos [2014] for what I mean)
>Things ~can get out of a black hole, both to the outside, and possibly, to another universe. So, if you feel you are in a black hole, don't give up. There's a way out. Reading that last line I couldn't help but wonder if all his fascination and interest in black holes is deeply rooted in the fact that that's how he actually feels :(
I think this lecture was very informative but also very easy to understand. It was very well written and interesting all the way through, even to me an I'm not very good a physics. I really admiret Hawking for, among many other things, expressing himself so well.
I'm the same way, anything related to physics I'm no good with, but I think as amateur cosmologist (which is what I really consider myself) it was very interesting. As is anything by NDT (Neil Degrasse Tyson). So when I was presented with the chance to read a couple of his (Hawking's) books, I took it and devoured A Brief History of Time (both the abridged and "normal" versions). I think I'm going to move on to reading Sagan's books next, since the original Cosmos (miniseries[?]) was so interesting, as is NDT's take on it. I think what I'm going to do next is find some of NDT's work and read it, since he makes cosmology and what not, seem extremely easy to understand or at least comprehensible... (Forgive my rambles, I'm not firing on all cylinders right now).
Are the books as easy to understand as his lectures?
