I sometimes sit and think about the heat death of the universe. In 10100 years, or a googol, I won’t be here to see it, but I think about all that will be lost when that happens. All the evidence pointing toward our existence will be gone. Documents about what we tried to do here, our triumphs and tragedies will disappear. Whatever living things that are left will be gone. Our only possible salvation would be the existence of the multiverse. If the multiverse were real, we might have a chance to survive elsewhere. Yet, it is highly unlikely.
