The rules of physics are pretty insane. Last week, we saw a single human accelerate through 23 miles of atmosphere: Felix Baumgartner actually moved faster than the speed of sound during his leap from the stratosphere.

People around the world were able to watch and discuss his space jump, in ways that would have been impossible only a few years ago.
