Here's a good rumor for you: the theory of relativity has already been thoroughly falsified.

For one, quantum electrodynamics, the best theory of light and matter, says photons have amplitudes that allow them to travel slower or faster than c. That breaks the postulates of SR (speed of light is constant, and c is max speed limit).

Secondly, dark matter. General relativity simply doesn't explain the gravitational effects of the outer movement of galaxies.

Last, the major prediction of GR has never been confirmed, the existence of gravitational waves.

Other peculiarities, such as quantum entanglement and the paradoxic possibility of time travel in GR, further cast doubt on the theory.

Science is built upon the principle of falsifying theories with experimental evidence.

Its love affair with relativity is not representive of its supposedly strict critical methods. Maybe the Eotvos experiment later this year will put the final nail in the coffin.
