If stars collapse in on themselves to create blackholes, would the end of the universe be a lot of black holes?

If E=MC^2, then black holes can't exist.

If E=MC^2, then E/M=C^2.

If If the mass (M) is destroyed, and the previous statement is true, then since M=0, E/0=C^2.

You can't divide by zero. Therefore, black holes cannot exist.

This is one theory on how the Universe might reach it's end (Known as the big chill)

Assuming the universes expansion is infinite and that Dark Energy does not interfere.

As Stars die some for Black Holes some Supernova and some Form White Dwarfs. Supernova leave around a bunch of gas and dust from which new stars can be born. Eventually the cycle will repeat until all matter is collapsed into Black Holes or spread too far apart to be of use.

Then as the Universe Darkens the void will be filled with ultra massive Black Holes (bigger than the ones found at the heart of most galaxies) will scatter across the void distanced away from each other Many many times larger than the current universe before they too evaporate and the universe is dark quiet and empty.

Sub-note: The previous poster has said that "if our sun were replaced with a black hole orbits would continue in much the same fashion" This simply is not true. The orbit of any one object around another is a VERY delicate thing. If you change any factor about it the orbit will collapse very quickly, as any orbit is a balance between the forces pulling you down and the forces pushing you forward. (essentially you fall downwards as fast as the object bellow falls away) Replacing the Sun which has 1 Solar mass with a Black hole (Usually around 4 + plus solar masses) means the forces pulling you down are much greater and we are not moving forward fast enough to escape that.

This does not mean orbit of a Black hole is impossible, in fact we are doing it right now. Everything in our galaxy Earth included is known to Orbit the Black Hole Sagittarius A*.

No not at all, the gravitational pull of a black hole is greatly exaggerated to the point that a if the sun was replaced by one then the planets in our solar system would continue to orbit it as normal. plus as some as the others said not all stars are big enough to create a black hole. On top of those two points even now with the amount of matter and black holes in the universe each with they're own gravitational pull, the rate of expansion of the universe is increasing. So in my opinion, no i don't believe it will. One theory is that eventually the universe will collapse inwardly on itself and the hole thing will start again. Fascinating Stuff!

The majority of stars are nowhere near large enough to ever become black holes. But, there would be a whole lot of them, yes. This kind of depends on how exactly the universe ends though, and how long it takes. If Hawking is right then given enough time black holes will radiate away all their mass and just fade away. If the "end" of the universe is a big freeze, and Hawking is right, then there won't be any black holes left, none.

I don't think so. Lot's of black holes would lead to rare mergers of black holes with each other and other things such as brown dwarfs and white dwarfs. Some particles would escape from the accretion disk, and polar jets, so there would be many small particles drifting in the vast space between the the galaxies if the universe continues to expand at an accelerating rate. Maybe in a google years, but even if there is nothing left but one universe mass black hole it is emitting Hawkings radiation so that is still not the end. Neil

Actually, most stars do not have enough mass to fall into their own black holes.

AND, BTW, it is not only the end of the universe.

The Big Bang created a whole host of small black holes that are still out there.

Most stars are not massive enough to collapse into black holes.

But given enough time, its possible that all the stars that are not black holes end up being consumed by the black holes in the centre of each major galaxy.

No. Evantualy even the black holes will fade away. And the entire universe will be just dust. Stars that dont turn to black holes will turn to dwarf stars, even they can fizzle out and become nothing

Yes.

Many massive stars, will in the future, turn into black holes.

And massive stars are forming all the time across the galaxy, and presumably in other galaxies.

So the number of black holes will increase over time.

But black holes do merge with each other when they pass close enough.

I agree with Aidan, the universe is always expanding. One day our sun will die and probably produce a black hole. However scientist say 99.9% it will happen in the next billion or million years. Think of black holes as vacuum bags. The vacuum (black hole) sucks, pulls, however you want to describe it objects and matter until one day it can't hold any more and explodes and causing what aidan said. The universe is always changing so it can be hard to tell.
