Not exactly.
An experiment may validate or invalidate the predictions of a theory or model, but in general, cannot “prove” the existence of one single theory as the only way of explaining their results.
Interestingly, the Michelson-Morley experiment, when evaluated from the perspective of Frequency, returns a result of 30 km/s. This was their expected result and support the idea of an electromagnetic ether. This finding challenges special relativity on experimental grounds.
Also interestingly, the Ives and Stillwell experiment is an example of an experiment where the results appear to be predicted by very different models; Einstein, Larmor-Lorentz, and more recently, the CICS model.
In addition, there are several speed of light experiments that suggest that the velocity of light can be slowed, stopped, made to go faster than 299,792,458 m/s, and controlled under the right circumstances. These findings are consistent with the expectations of a Complete Coordinate System, but require extensive “explanation” as to why they do not contradict the SRT postulates.
