One of the biggest weaknesses of people, it seems to me, is to assume we know more than we actually do.

Studying a subject reveals more questions than answers, expressing certainty on anything reveals a certain lack.

Ask any scientist, they will confirm. Or perhaps you know more, and can explain the underlying mechanism of gravity?

Gravity is also the only force with no known opposite.

The fact we’ve studied its effects forever, and still don’t know how it works makes it all the more intriguing.
