Will Black Holes destroy the universe and eventually cause another big bang?

Answer 1

Um... No and Yes?

The Universe has infinate volume. Most of this volume is empty...

A Black hole has no more gravity than the star and matter that has fallen into it, so never fear that everything is going to be pulled into a single super Singularity...

As to it eventually causing another "Big Bang"... How do we know that a "Black Hole Singularity" is the "Big Bang Singularity" of another universe?

Black Hole Theory states that a Black Hole is so massive that it gives space infinite curvature...

Presuming that the multi-dimensions discussed be the Super String Concepts exist...

Then how do we know that this infinate Curvature does not extend to an infinate volume of other spacial dimensions?

Or rather... Give thought to the possibility that a Black Hole Singularity is the "Big Bang Singularity", and that our entire universe of infinate space may exist in the Black Hole in another Universe that uses diferent spacial Dimensions...

There's no evidence either way... So to answer you question which askes for definate answers that no one can give definately, let me say...

Probably not but Maybe yes... But Maybe yes but not really... 8-)

Answer 2

If the universe is massive enough, it will collapse to a point mass under current understanding (general relativity). We have no reason to believe this would cause a big bang, although we still don't have a good explanation for the original one so it's possible as such.

If the universe isn't massive enough, it will continue to expand forever (getting increasingly dark as matter is increasingly isolated).

Either way this has little to do with black holes. If the first ("big crunch") theory is correct the universe would form a black hole, but that doesn't mean much -- as I understand it the universe is probably a black hole right now. (Larger black holes don't need to be as massive.) Look up information on the Schwartzchild radius for more information.

Answer 3

Black holes may eventually consume the Universe if it has sufficient mass to overcome expansion.

However, this will definitely not itself lead to another big bang. The reason is that black holes are known to have the higher possible entropy per unit volume achievable in the universe. By contrasst the big bang is the lowest entropy the universe ever had. Black holes therefore could not lead to another big bang because this would violate the laws of nature - it would reverse entropy, which is not possible.

Answer 4

Wow. Where did you hear or think of that?
I really don't know, but theoretically if there are enough black holes formed from collapsing stars, then eventually the huge amount of mass being sucked into the black holes might cause the Universe to collapse on its self. Therefore becoming either one giant black hole, or like you suggested, causing another big bang. If we really for sure knew that there was nothing beyond the Universe, then this would be easier to answer. If there is really nothing beyond, then perhaps there could be another big bang. If there is something beyond, then I have no clue. I think that there is something beyond the Universe, but it is far past any human understanding because we have no way of observing it.

What if the Universe does cause a big bang again, how do we even know that it hasn't happened before? Maybe the big bang that caused us was the 100th time it's happened? We are only here for a short time, I wish I could learn the answers to these questions myself. Thanks, you helped me want to become an Astronomer again.

Answer 5

I'm pretty sure this used to be the general theory behind the universe's future, that we would all eventually slow down from the big bang, collapse and maybe do it all over again. But because of recent findings most people these days agree that the universe is not only not slowing down, but it is actually accelerating away from itself. What that would mean for the future, can't really say, I'm sure there are good guesses, something along the lines of sub-atomic particles ripping apart and nothing holding shape, but who really knows.

Of course, this can change a month from now, dark matter and energy is so little understood that we can't really be sure of much that we believe as of now.

Answer 6

Not really. Black holes are very stable. What you should be wondering is that galaxys are moving away from each other at an accelerating speed. This means that billion years from now, stars will be so far that the sky will be left without them. I think that universe will expand at extreme amounts and then collapse in a single point. When it collapses, it will invert and start a new big bang in another dimension.

Answer 7

Bits of it. Like all objects its gravity greatly decreases as you move away, many stars orbit black holes and will live out their full lives none the worse for ware. They also evaporate over time (a lot of it) so they are not permanent either.

Likely, big bangs happen all the time, all over the place when enough matter happens to condense at one location.

Answer 8

I would say no at least not for 1x10^1000 years because the more gravity the slower time goes so as a black hole grows in size (and gravity) it's growth slows but never completely stops. like dividing a number by 2 it will never become 0. It will keep growing but at such a slow rate that it is pointless.

Answer 9

no first of all Black holes are very rare for every galaxy there are very few stars that can go supernova and fewer stars have enough mass left after a supernova to turn into a black hole.

Answer 10

Yes, absolutely! Your only hope for survival is to join me in my IUD (inter-universe delivery) craft. I'll leave the light on. Hurry!
