A recent published work suggests that when two progenitor galaxies collided head on, their dark matter and stars would have sailed past each other. The galaxy collision is one of the most beautiful balletic things you've ever seena. Gas clouds cannot move through other gas clouds without consequence. Why are you a solid object, chuck? Because your molecules are sticking, sticking to each other in some way that turn you into chuck. And it's like two hot marsh mellows touching each other. They stick, right?
What happens when two galaxies collide? On this episode, Neil deGrasse Tyson and comic cohost Chuck Nice answer questions about explosions, asteroids, quarks, and all things that go BOOM. Was our Big Bang someone elses Big Rip?
