Isn't it amazing to think, that in 1.5 billion years the sun will reach a stage where life on planet Earth will become impossible? Not only that, but in 7.5 billion years, Earth will pretty much be desintegrated. It's just incredibly cool to think humanity will have to travel and colonized other planets if it wants to survive. Basically, Alien Covenant where humans were cryogenized until they could find a good enough planet to inhabit. Fucking cool.
