If black holes suck all matter into a singularity, where does it go and what does it do from there?
No one can answer that for sure; that's one of the defining characteristics of a black hole. All information is destroyed after entering one, so there is no way to interogate a hole to find out what's going on inside. The matter itself is destroyed on the way in; what becomes of the resultant energy is speculative.aricho said:If black holes suck all matter into a singularity, where does it go and what does it do from there?
Is that the latest view? I read something in Scientific American (I think it was) a loooong time back about the possibility of information being conserved holographically in a black hole (I know nothing about holography), and also that it may be retrieved (albeit randomly) in the form of Hawking radiation. Do either of those points make any sense, or is it another case of facts being lost in translation to layman's language?Danger said:No one can answer that for sure; that's one of the defining characteristics of a black hole.

Well, no-one knows the laws of physics in a black hole, so no-one can answer that. There are theories (cosmological Darwinism and black-hole bouncing) that suggest a universe may be created by a black hole, but I don't know if anyone gives these theories much time. When it comes to 'in' a black hole, I guess you can ask any question you like but no-one knows the answers.aricho said:could our universe be in a black hole? Could the "Big Bang" have occurred from the possible "singularity" inside a black hole.
Sure.aricho said:Also, i know that light can't get out, but can light get in?

I was kinda kidding about that part of it. The uncertainty principle and chaos theory would rule out an exact duplication even if the resultant new universe began exactly the same as this one. Think of how different just our own little planet would be if, for instance, Napoleon had died in childhood. Extrapolate things like that to an entire universe, and you just couldn't end up the same way twice.cDimino said:Hmm that provokes an interresting thought; say the big crunch occurs, and then it expands again as the big bang. Wouldn't it turn out to be the EXACT SAME universe as it is now?
Didn't Stephen Hawking recently admit he lost a bet against two other physicists (cosmologists?) on whether information can escape from a black hole? (Hawking had bet on "no information escape.")Danger said:... All information is destroyed after entering one, so there is no way to interogate a hole to find out what's going on inside. ...
A black hole singularity is a point of infinite density and zero volume at the center of a black hole. It is where the laws of physics as we know them break down, and our current understanding of the universe cannot explain what happens inside this point.
Black hole singularities are formed when a massive star collapses under its own gravity at the end of its life. As the star's core collapses, it reaches a point where the gravitational pull becomes so strong that it overcomes all other forces, causing the singularity to form.
According to our current understanding of physics, nothing can escape from a black hole singularity. The gravity at the singularity is so strong that even light cannot escape, which is why black holes are known as "black".
Entering a black hole singularity is not possible according to our current understanding of physics. As an object gets closer to the singularity, it will experience extreme tidal forces that will stretch and tear it apart. At the singularity itself, the object will be crushed into infinite density.
Since we cannot directly observe black hole singularities, scientists study them through indirect means such as observing the effects of their gravity on surrounding matter and using computer simulations. However, there is still much that is unknown about these mysterious objects and more research is needed to fully understand them.
