Find me any competent scientist who doesn't believe in gravity. I'll be waiting.

I don't "believe" in gravity. I don't have to "believe". I can measure it. However, gravitational theory can and will be revised as new data is uncovered/discovered.

This is different than a "belief" system.

Can gravity be proved?
