Ultimately, as far as I’ve read and understand, much like the weather, science does not have the answer to gravity.
Yes, it can we witnesses, it can be watched and measured, but it can not be created nor manipulated.
The point is that the theory of gravity can be proven using the scientific method. We can predict based on the theory of gravity exactly what will happen, and it happens every time. The theory of man made global warming has produced predictions that almost never happen, yet it’s advocates try to mock skeptics by saying “yeah, well gravity is a theory too, so jump out of a building”.
