and I can suggest some experiments to test gravity ...
actually gravity is a very good example ...
Newton's gravity works on earth, but not in space.
Einstein's gravity works in space as long as you don't worry about galaxies ...
... gravity doesn't work at the level of galaxies without adding fudge factors of dark matter and energy ...
... and there has been no "graviton" found ...
so we have theories that come close, but are not perfect. that's science.
we are limited in our ability to understand
by our ability to understand
