Science definitely hasn’t figured things out, and that’s what makes it exciting. There are all sorts of blindingly obvious things we still don’t know.

Why do we sleep, anyway? Why does every living thing seem to sleep? Even microscopic organisms demonstrate sleep-like behavior.

Theory says time travel should be possible. In fact, theory says there’s no difference between the past, present, and future. Obviously that’s not the case. What’s up with that?

Our common sense is based on extremely parochial conditions. We are these tiny little creatures living in a micro-instant of time, and the universe contains multitudes that are both vastly bigger and smaller than we are,. A lot of it moves a lot faster than we do. Get down to the subatomic scale, or up to the interstellar scale, and things are very, very different.
