Imagine 5 billion years from now. If... the human race survives then they too will be faced with an existential dilemma too. The sun will eventually burn out and everything in our solar system will become extremely cold and probably die. Maybe except for the extremely tiny bacteria that survive those conditions. To me, this is very troubling, but also very telling of how the universe operates. It doesn't seem to care.

It is sad, but it's also the way it has to be. Life has to continue on, and the new memories will again fade out. It's more reason to make the best out of this life while your living it and be thankful if your fortunate enough to be around good people. And if your not, don't despair because there are plenty of good people in the world and it's worth every bit of your time to find them and enjoy their company. They will enjoys too.
