Related: About this forumOK - I have some questions about this whole "we might be in a black hole" thingy
http://news.nationalgeographic.com/news/2010/04/100409-black-holes-alternate-universe-multiverse-einstein-wormholes/So if I get this right, the black hole's collision with a bunch of stuff might have come out the other end of a black hole and provided the matter and catalyst for the big bang?
Or am I not getting this right?

(55,476 posts)It will have nothing to do with black holes, but instead a romcom where the two have nothing in common but a bond over astronomy and it will be this discussion they are having that gives the movie/book it's title.

(114,616 posts)we have absolutely no idea what is going on inside a black hole. The multiverse explanation is one theory, since beyond the event horizon, time, space and matter have nothing to do with the way they are in ordinary space/time. Another theory is that black holes dig a gravity hole so deep it forms a "wormhole" into another universe, this was Einstein's idea.
Not only do we not have any idea what's going on inside a black hole, we have no idea of its longevity. Hawking thinks they just evaporate away over billions (?trillions) of years. Or they might collapse into a singularity which is inherently unstable and burst forth into a big banglet, something that might explain the gamma ray bursts at the edge of what we can now perceive.
All of this stuff is highly speculative and great fun to read about, but it's largely supported by math and supposition. Much of Einstein's stuff has been proven, such as the lensing effect of a black hole. It's really a pity he didn't have a Methuselan lifetime to be able to see what's going on now.

(114,616 posts)"Feeding" black holes have extremely energetic jets of radiation at their poles (or the direction perppendicular to the disc of matter hitting the event horizon). Whether they convert the disc of dust and gas falling into the event horizon directly into these jets or if there is an upper limit of matter they can somehow handle is unknown.
That's the best part about all this stuff--we have no way of directly observing any of it so we're left with a lot of questions and questions are fun. Things get rather dull once they're answered.
Eventually the math geeks might be able to answer this stuff when they can quantify the amount of matter hitting the event horizon and the energy shooting out. For now, an old broken down ex RN in New Mexico can dream about it with the big boys.

(9,402 posts)Supernovae perhaps? Is that what the article is saying? But don't they collapse into black holes? Or only sometimes? What is breathes? In and out. Out and in.
doesn't that mean though that, somewhere in the universe, there is the entrance to the black hole we were created from?
And wouldn't that mean that if that black hole occasionally is sucking down new material, as one would expect it would, that we would see with some frequency, the same spot in the universe spitting out multiple episodes of new material?
Assuming the "parent" universe hadn't reached full entropy of course.

(3,626 posts)but it would mean that the universe as a whole is no longer a closed system, and that would suggest that occasionally energy is fed in from the outside (as the progenitor black hole eats something--although you'd guess that virtual particles would also be funneling in if Hawking radiation is true--so even then something would always be coming in).
So wouldn't that say some things about entropy and the ultimate fate of our universe?
