My best friend and ex-roommate is doing a double major in physics and astronomy. He owns three telescopes and works at an observatory. We sit and talk about philosophy and space over beers very often. I've learned so much stuff from him, and he's probably the only reason I'm interested in astronomy. I've spent quite a bit of time reading random stuff on Wikipedia and checking out space books.
My favourite thing about space is Obler's Paradox. Link
It's the idea that since there are so many stars in the Universe, when we look up at the sky, every point should terminate on the surface of a star, and thus there would be no "night". That doesn't happen because the stars are so far away that their light hasn't reached us yet. Just blows my mind.
