Years ago, Bozhidar Danev (my friend, head of the Chamber of Commerce at the time) called me and said: “Stojane, I know that you are not only a good mathematician, but also a physicist, and that is why I am sending you a man, with the request that you just listen to him. He will tell you crazy things, but he is not crazy...“
And indeed, a few days later, Mr. Sasho Sulkov came to me with his newly published book “Theory of Absoluteness“. The provocation was already evident from the title. Like most people, I initially reacted with slight mockery and distrust. Then he explained to me that it was not a direct conflict with Einstein's Theory of Relativity, but rather about its foundation - the Law of Independence and Constancy of the Speed of Light in Vacuum.
More precisely, about its second postulate, namely, independence from the receiver. This postulate is based solely and exclusively on the so-called Michelon and Morley experiment. Then he showed me a computer simulation that he had made, where a fundamental error made (according to him) in the experiment is clearly visible. Then he showed me his experiment, where this error has been eliminated and it shows a diametrically opposite result.
I read the book with interest. I think it was worth reading. Anyway, we later became close and he joined UniBIT as a freelance researcher. In the process of our joint work, we attracted several new researchers who proposed some innovative technologies in the field of energy that will soon be on the market.
However, recently we talked again about his experiment and the possibility that the Law we were talking about is not true, and I became curious about what Artificial Intelligence would say on this occasion. I asked a simple question: “What happens if the law of independence and constancy of the speed of light turns out to be wrong“ ?
Here is what Chat Gpt answered me:
"If the law of independence and constancy of the speed of light, which is the basis of Einstein's special theory of relativity, turns out to be wrong, this would have profound consequences for physics and our understanding of the Universe. Here are the main possible consequences, explained briefly and clearly:
Revision of special relativity - The constancy of the speed of light (c ≈ 299,792,458 m/s in a vacuum) is a key postulate of special relativity. If this postulate were not valid, fundamental concepts such as time dilation, length contraction, and the equivalence of mass and energy (E=mc²) would be questioned or require significant modification.
Impact on general relativity - The general theory of relativity, which describes gravity, is based on special relativity. A change in this law would affect the description of gravitational phenomena, including the motion of planets, black holes, and the expansion of the universe. Quantum physics and fundamental theories: Many modern theories, including the Standard Model of particle physics, assume a constant speed of light. If it varies, this may require new models for the interaction of particles and fields.
Cosmology and understanding of the universe - Observations such as the redshift and the microwave background radiation depend on the assumption of a constant speed of light. If it is not constant, our calculations of the age and size of the universe would change.
Technological implications - Technologies such as GPS, which rely on precise calculations based on relativity, would be affected. This could lead to the need for new methods of timing and measurement.
New physical theories - The discovery that the speed of light is not constant would open the door to new theories to explain observed phenomena. For example, hypotheses such as Variable Speed of Light (VSL) or modified versions of Lorentzian physics would receive more attention.
Philosophical and epistemological questions - This would question the way we construct scientific theories and encourage a rethinking of the foundations of physics, as well as the trust in experimental data.
What would prove the law wrong? To prove that the speed of light is not constant or independent of the reference frame, repeated, high-precision experiments would be needed that show discrepancies with the predictions of relativity. For example: Observations of ultrafast particles (such as the OPERA neutrino experiment in 2011, which initially suggested a faster-than-light speed but was disproved). Cosmological data showing discrepancies in the propagation of light through different media or epochs. Probability and current status: As of now (September 4, 2025), there is no convincing experimental evidence to disprove the constancy of the speed of light.
Special relativity has been tested repeatedly with extraordinary precision, and all the data support Einstein's postulate. However, research in the field of quantum gravity and cosmology continues to explore hypothetical scenarios in which the speed of light can vary in extreme conditions, for example near the Planck scale“.
I expect Mr. Sulkov to confirm his assumptions experimentally soon. And …if the law of the constancy of the speed of light turns out to be wrong, this would cause a revolution in physics, requiring new theories and experiments. For now, however, it still remains one of the best confirmed foundations of modern science.
I think that soon I could establish contact with Mr. Elon Musk, with whose help I hope to carry out one of the experiments set out by Sasho Sulkov in space.
Interesting, isn't it..
