Two hot marshmallows will stick to each other because they're both hot. Dark matter is the unibomber, just what? Lone. It's a lone wolf. It's out there by itself. And it does not care. The interesting part is that it doesn't even interact with itself, physically, only through force of gravity.
What is nothing? Does nothing exist? Neil deGrasse Tyson and comedian Chuck Nice explore cosmological curiosities about the end of the universe, dark matter, and more!
