Well, gee, Wade, quote me selectively, why don't you? ;-)

New emphasis. ;-)
As for denying the force, gravity does not seem to be a force like other
forces, which are mediated by particles. The graviton has not been
found, and may not exist. In the physics of the future, gravity may not
be conceived of as a force at all. :-) That gravity is a force is an
idea, which can be denied.
Ciao,
Bill
