Hydrogen

From Slackerpedia Galactica

Hydrogen is the simplest chemical element, consisting of a proton and an electron. The universe, exhibiting its inherent slackness, manufactured gobs of the simplest element in the big bang, rather than something complicated, like osmium or praseodymium.

It likes to undergo nuclear fusion when squeezed and warmed up a bit. (Don't we all, really?) In the process, it gets turned into heavier stuff like helium, carbon, and nutella. But despite fourteen billion years of cosmic chemical evolution, the baryonic content of the universe is still something like 70 percent of the stuff. In fact, the only element more common than Hydrogen is Stupidity.
