All of it fascinates me.
So much that i'm considering going for the field of astronomy and astrophysics at Iowa next year.
As I understand, space is full of impossibly cool shit always just outside our reach that I want to visit all the time. I want to see big immense Gas Giants with planets orbiting around it. I want to see what kind of life is possible out on other earth-like planets. I want to observe Quasars and watch a black hole completely absorb a sun. I want to land on a planet that orbits an even larger one and see said planet looming over the sky.
There's so many possibilities out there, and for me it's the biggest source of adventure even possible for mankind anymore. I am fascinated that we haven't even seen 0.01% of the observable Universe yet, and I want to be able to see it all.
Video games appear to be the only thing in my lifetime (unless it's true that our new generations may live a long time) that will even get me close to that experience.
Elite Dangerous seems to be the closest to that, but the planetary landing doesn't have atmospheres/ skies yet, so until that comes out, I wont be awed. No Man's Sky will hopefully have it done pretty well. The day it happens for Elite: Dangerous is the day I buy my Oculus Rift, so I can just jump out of my ship, walk along the surface, and look up to behold the gigantic magnificence of an insanely large planet.
Space is my version of art.
I just want to observe it.
