RIP Future Gohan
We live and die but our place as human beings in the universe is so insignificant to the bigger picture and the workings of the cosmos that it makes life seem so dreamlike. Endeavor to live your life being happy and seek that which you want and erase that which you do not for it is your story to create.

Probably not even anything after death. We stress ourselves out over all the bullshyt in life when we should just be maxing and relaxing on the beach until the grim reaper decides it's our time....
Knowing this also gave me the attitude of not giving a fukk so that helps. 
It's impossible to travel past the speed of light and it'd take too long to get out of the galaxy. If we did have ships with a population on board, wouldn't there be inbreeding? Only way I can see us doing this would be wormholes.
