The infinite vastness of space.

Man, only reason I would wish for immortality is to be able to be present when humanity's perception of what space is changes. Just like back when people thought the Earth was flat, I'm pretty sure there are lots of surprises awaiting out there. But that's still so far away.

In a way, it's depressing. ;_;

It sure is depressing, but you can make a difference by helping future humans get to that point. I just hope that humans don't destroy themselves before they can travel the cosmos.
