Be happy you can actually see the universe. Some aliens in a distant future might never be aware that there’s something else, because light will be shifted so far it’s impossible to understand. There will be less and less stars anyway, so it’s going to be a lot darker.

Maybe protons aren’t actually stable and they will break apart too, at some point, and then the last thing will be black holes slowly dissolving due to Hawking radiation.
