Humans have always had a big gap between "how we understand" and knowing everything. Plenty of stuff in physics doesn't make intuitive sense, and there are things like https://en.wikipedia.org/wiki/Alcubierre_drive theorized that wouldn't require brute force exceeding C.

That drive has a bit of an issue that even if it worked, it would probably destroy it's destination in a annihilating blast of gamma radiation on arrival.
