Is There a Rival Theory of Gravity?
In the case of newtonian gravity, the postulation of a physical force, an action at a distance that travels instantaneously between bodies ia. Thatsay, that's postulating a real physical thing that we can experimentally test for, and in fact, fails to test. And on the other hand, you've got general activity, in the existence of a true fabric of space time that can bend and warp in the presence of mass and energy. And we can test for that too, and infact, passes the test. Now not to say that it's confirmed as true or anything like that. I just it's gone unrefuted. If you want to explain stuff
