NGT: The nearest large galaxy to our own Milky Way is called the Andromeda Galaxy. We are on a collision course with one another. In about seven billion years, we will collide. Our beautiful spiral patterns will be completely distorted, and in there gas clouds will collide, sticking together like two hard marshmallows. Where they stick, stars are born. We have a black hole in the center of our galaxy, and so does Andromeda. Those black holes will one day find one another and collide. Such is the fate of the Milky Way system.

NGT: Jupiter and Europa and its system is well outside of the Goldilocks Zone of the sun. Everything should be completely frozen out there, but it’s not.

NGT: You want to avoid black holes. You fall in, you’re not coming out. It distorts the fabric of space and time, and you’re occupying the fabric of space and time, so you get distorted. Your feet will fall towards the center of the black hole faster than your head does, so you will snap into two pieces and then your two pieces themselves would snap into two pieces. You’d go from one, to two, to four, to eight, to sixteen, to thirty-two—all the way until you are a stream of atoms headed to the cosmic abyss.
