At the bottom of every great scientific discovery is a question. Often, the simpler the question, the more fascinating the answer.

It’s these big, juicy questions that keep scientists going. We’ve worked out the answers for some, but others are still out there. And the best thing is, an answer usually leads to a new question.
For now, feed your curiosity and impress your friends with these fascinating factoids.
