Imagine still being alive to witness the slow, agonizing death of the universe, when all matter and energy are evenly spread across an incomprehensible vastness, and nothing will or can ever happen again. The next billion years would be fairly interesting until the sun expands and swallows the Earth…or, at least, dries up its oceans. Hopefully, you’ve found a way out and onto another planet for another billion or so years. But after about 170 quattuorvigintillion years of cold, dark, nothingness, you’ll probably get pretty bored of it all.
So far, I think the general consensus is heat death. Being an optimist, my hope is for the big crunch. If that one’s true, what’d be infinitely hilarious is if it always repeats in exactly the same way.
If that’s the case, then I guess all of us do truly live forever. We just microdose the same exact snippet of eternity.
So much of what exists is spheres and circles. Who’s to say time doesn’t also run in a circle?
