Two things about space freak me out
>eventually, on the scale of trillions of years, everything will be so spread out/redshifted that there will be nothing in the observable universe outside of our galaxy and some local galaxies
>any number of things could randomly end life on Earth (collision with a giant undetected asteroid, gamma rays stripping the atmosphere, rogue planet approaching our solar system and fucking up Earth's orbit just to name a few) and we would be absolutely helpless to do anything about it
