It turns out there are several theories of how aircraft can get off the ground. But most of them are debunked.

That’s the importance of the scientific method. We can keep testing until we find a reasonable conclusion. Until we discover the next thing.

What we think is possible and how we explain it are two different things. Sometimes we know something is true and yet we have not found an explanation. Indeed, waiting to find the right answer instead of rushing to find a good enough answer, takes lots of patience but also solves future problems because we are seeing things more clearly.
