I believe the universe to by cyclical. I'm not sure which video you are referring but I can presume it shows a very long dark quiet and cold end to our universe?

Eventually nothing can hold a bond and all matter will just slowly fade away, with a fizzling out of energy.

The time frames are astoundingly unfathomable.

I like to think/believe in the big bounce. It would be a lot cooler if there was something out there yet discovered, maybe just beyond our vantages horizon that would cause the eventually reverse of time, the collapse of this universe back up onto itself.

Maybe, just maybe, just an atoms length beyond our horizon, there exists a black hole the size of the entire horizon.

So I guess in summary, I'd (the universe) rather die in a black whole than being stretched out into nothingness via a long dark cold freeze. Although, being stretched out into nothingness also seems to be what would happen if we were to enter a black hole? So wait, what we are experiencing now is what would happen if we were to fall into a black hole? So, we are in one now?

Or maybe my therapist is right.
