Is it possible that gravity is not what we have thought it was?
Or more likely, that there is more to it ?

As admitted amateur who is nontheless fascinated by all this stuff, have always believed that one day it will be shown that gravity is NOT a property of matter, but that matter is a property of gravity.

I will consider believing in dark energy/matter when physicists prove to my satisfaction that they haven't just underestimated the mass of the black hole at the center of every galaxy.
Of course this is simplistic but it explains all the missing matter in the universe.
