Neil deGrasse Tyson just blew my mind

"And are we the only universe out there? Could there be - a word for it - a multiverse? Where there are multiple big bangs going on and multiple expanding universes. And there's good philosophical reasons to think that, as well as mathematical.

"But philosophically, what used to be: well, we're on Earth, and nothing else looks like this, so we're unique. Nope, you're one of 8-9 planets orbiting a star. Well the Sun is surely special, look how bright it is! No, all the little dots of light on the sky, those are stars too. Oh well surely this collection of stars is THE universe? Nope, no, it's just a galaxy, there's a 100 billion other galaxies. OK so all these galaxies, that must be THE UNIVERSE! Yeah, we've got the one universe. Well... maybe there's more than one universe.

"So suppose we do learn that we're in a multiverse... but then you have to ask, are we just one of many multiverses?"
