I Relative Velocity Time Dilation: Experiments Disproving Theory?

I have a question regarding time dilation due to relative velocity. (It's just about time dilation due to velocity not about gravitational effects.)

I have seen a theory where time dilation is not relative, but always considered against an absolute frame of reference. The absolute frame of reference is given by the origin of an inertial frame with zero total momentums. Time dilation is calculated in the normal way, but the velocity is always referred to the absolute frame. (This means that there is a state of absolute rest and motions of inertial frames of reference relative to the absolute frame can be measured.)

Of course, this theory is in disagreement with special relativity. Since the velocity of the Earth is about 369 km/s - taken from cosmic microwave background - there should be experiments with are in disagreement with this theory.

For example I had a look here: "Optical Clocks and Relativity" C. W. Chou, D. B. Hume, T. Rosenband, D. J. Wineland. However, due to the "harmonic motion" in this experiments, I found that the results are in agreement with the theory. (First order effects are the same for both theories and second order effects are too small to see them.)

There are many other experiments about time dilatation. Are there experiments which disprove this theory?

(Sorry for my spelling and grammatical errors.)

"I have seen a theory" is not acceptable reference under the Physics Forums rules - you have to be able to point to something that has undergone some level of peer review so that it is clear what this theory you're asking about is.

There's no way of answering that question until we know what theory you're asking about. However, you may want to review this FAQ on experimental support for relativity, see if you can find what you're looking for there: https://www.physicsforums.com/threads/faq-experimental-basis-of-special-relativity.229034/

OK, so this has bugged me for a while about the equivalence principle and the black hole information paradox. If black holes "evaporate" via Hawking radiation, then they cannot exist forever. So, from my external perspective, watching the person fall in, they slow down, freeze, and redshift to "nothing," but never cross the event horizon. Does the equivalence principle say my perspective is valid? If it does, is it possible that that person really never crossed the event horizon? The...
ASSUMPTIONS 1. Two identical clocks A and B in the same inertial frame are stationary relative to each other a fixed distance L apart. Time passes at the same rate for both. 2. Both clocks are able to send/receive light signals and to write/read the send/receive times into signals. 3. The speed of light is anisotropic. METHOD 1. At time t[A1] and time t[B1], clock A sends a light signal to clock B. The clock B time is unknown to A. 2. Clock B receives the signal from A at time t[B2] and...
From $$0 = \delta(g^{\alpha\mu}g_{\mu\nu}) = g^{\alpha\mu} \delta g_{\mu\nu} + g_{\mu\nu} \delta g^{\alpha\mu}$$ we have $$g^{\alpha\mu} \delta g_{\mu\nu} = -g_{\mu\nu} \delta g^{\alpha\mu} \,\, . $$ Multiply both sides by ##g_{\alpha\beta}## to get $$\delta g_{\beta\nu} = -g_{\alpha\beta} g_{\mu\nu} \delta g^{\alpha\mu} \qquad(*)$$ (This is Dirac's eq. (26.9) in "GTR".) On the other hand, the variation ##\delta g^{\alpha\mu} = \bar{g}^{\alpha\mu} - g^{\alpha\mu}## should be a tensor...
