Most people think we understand gravity better than we actually do.

To compare it to an actual hot-button issue, we know more about the mechanisms of evolution than we do about the mechanisms of gravity.

We know kind of how it behaves at various scales, but we don't know why it does. We don't know what makes gravity. Why do denser objects have more of it. Why is it weaker than other forces, yet felt on larger scales? Does it actually exist or is it an emergent property kind of like the centripetal force (or is it centrifugal, I keep getting those flopped)?
