Einstein's equivalence principle is like great art and music - deceptively simple, yet one sees more facets of it every time one looks at it again. All attempts to modify it fail. First they are clumsy conceptually and second they fail experimentally.
I know of no experiment that shows a violation of the equivalence principle - not even a quantum one. Does anyone have info to the contrary? Einstein's general theory of relativity of gravity is considered by all the top level theoretical physicists in the field who are big professors at the best universities and who control all the money in the field to be the most beautiful theory in all of physics. I agree with them on that point 100%. That is why the attempts to modify it are held in disrepute. Note I said "modify" I did not say "extend". What's wrong with Hal Puthoff's PV and with Heim, and with Yilmaz, not sure about Woodward, is that they attempt to modify Einstein's theory inside its battle-tested domain of validity. I am not talking now about extending it to say the torsion field theory. That simply means locally gauging a larger space-time symmetry group than is done in Einstein's 1915 theory. Einstein did not use modern ideas of local gauge invariance back then - they had not yet really been invented. At any rate Einstein did not understand that idea the way we do today. Lenny Susskind has a good discussion on this pp 114-16 of Cosmic Landscape including Feynman's approach explained nicely. One also sees why Puthoff's idea to use a background flat space-time co-existing with curved space-time is simply no good at all. The modern approach that Einstein did not use historically does prove a kind of uniqueness "that it could not have been otherwise" p. 116 Susskind.
Note the equivalence principle is that the force of gravity is locally indistinguishable from an inertial acceleration force that is felt when, for example, an elevator starts to move or stop, or you step on the gas of a powerful car. This is called universal g-force. All objects experience it the same way!
This also leads to the notion of the "geodesic" in which one is weightless or free-floating. That is, there are geodesic paths without the time dilation of special relativity in which one is continuously weightless! The time dilation (shortening) is only detected when observers take non-geodesic paths in which they feel weight at least on parts of the trip. The non-geodesic traveller always feels some non-gravity force whenever he/she feels weight. The best way to see the time dilation is when two observers start and end their trips in local coincidence. The observer who felt no weight ever will be older than the observer who did feel weight. That is time dilation. The effect is usually very tiny of course. If both observers feel weight there is no general rule who will be younger. It's all contingent on details of the applied forces on each of them. Also to measure the curvature of space-time we never should apply forces to the pairs of test particles used to measure components of the space-time curvature, i.e. geodesic deviation.
Now if you cannot understand everything I just said, you cannot understand what warp drive is all about and how the Skinwalker Ships really work.
As soon as I hear the word "thrustor" I take out my post-quantum eraser and DELETE it.
