The most commonly held theory is "heat death" - the supermassive black holes at the centre of all galaxies eventually consume all of the material within those galaxies, then dissipate by Hawking radiation over trillions of years.
However, honest scientists will not rule out the possibility, however unlikely, of a "big crunch", the universe collapsing under its own gravity back into a singularity again. Gravity is a weak force, but when it's the only force still in existence ... after all, we DON'T know how dark matter and dark energy will behave in the absence of normal matter and energy to interact with, and "Hawking radiation" is entirely theoretical - a mathematical model that may prove to be erroneous. The late Professor Hawking may have been a supergenius, but he wasn't infallible. Anything that cannot be tested by experiment and observation is theory. Hawking radiation has never been detected.
Do you know how many more years of other really great future technologies will come to Earth that are really new, before there may not be any more left?
Can you check list when or in what year will the planet Earth, the stars, then black hole, etc. will be gone at?
Any other possible (technological) scientific fact that you can tell me, that which would prevent from everything in the universe to slow down & got stopped in coldest space forever?
Well I think you can stop worrying about The Big Bang Theory in reverse thing because they figure it will take about 10 million years to happen. Cheers!
I might still think of what all else we can do to keep the universe saved just before it lose the universe - to get the universe come back whenever the universe may ever get flown away - even if the universe have been about billion, trillion, or even a googol years there! -'To constantly keep the universe lit-up, just to prevent from being gone forever'
Any other questions or comments about through that whole trillion/googol years stuff that I was typing the universe stuff on with?
Yeah don't go back in time because you could inadvertently mess up the future. If you don't believe me just ask Doc from the Back To The Future movie he will tell you how dangerous time travel can be. Cheers!
I know something so abstruse that people refuse to accept it. It is call The Big Crunch. There.

If you see any mistake here of any spelling or sentence, correct them: But here's the other message about these universe, big crunch, etc. stuff
Okay I just watched this whole video, Then can anyone tell if there's anything else different will happen-later-after the big rip or big crunch - in what huge number of years that will happen after? (As does the universe won't (ever) end, until it forms into ether the Big Rip or the Big Crunch?)
They can't really tell for sure if the universe will stay in steady state forever or not, can they?
Where would you/I will go (to), after get swallowed up by a black hole, (after death), or after the whole universe stops moving as gets into the coldest state?
