So, Neil deGrasse Tyson is awesome, with a capital AWE. Here's one reason why. This is a video of Tyson describing the single most astounding fact about the universe.

Of course, the other thing that I love so much about him is the way that when you look at him, his eyes are like "I would like to make sweet, sweet love to you," but then his clothes are all, "but I am physically incapable of doing so."
I mean, seriously, how can you not love this guy?
