Theory of general relativity-- Falsifiable? "... Supposing that the bodies act upon the surrounding space causing curving of the same, it appears to my simple mind that the curved spaces must react on the bodies, and producing the opposite effects, straightening out the curves. Since action and reaction are coexistent, it follows that the supposed curvature of space is entirely impossible - But even if it existed it would not explain the motions of the bodies as observed. Only the existence of a field of force can account for the motions of the bodies as observed, and its assumption dispenses with space curvature. All literature on this subject is futile and destined to oblivion. So are all attempts to explain the workings of the universe without recognizing the existence of the ether and the indispensable function it plays in the phenomena." -- Nikola Tesla I completely agree that this is a bold statement by Tesla but, nevertheless, a reasonable one. And I think that it seems more plausible that tesla's dynamic theory, having a field of force connects to the natural world rather than a presumed curved spacetime. That a medium where all fundamental forces such as gravity is much more coherent in our universe. So with respect to these statements what are your opinions of tesla's theory, in contrary, to Einstrein's?
