To doubt the validity of Einstein's theory of relativity in our time, when it is already used in everyday life, at least not wittily, Each of us uses its achievements almost repeatedly on a daily basis. This is especially evident in global positioning systems, which are now widely used in everyday practice. Without maintenance-based corrections, such systems cannot provide an error of less than +-30 meters, which is not sufficient for many applications. Adjusted for that, the accuracy is practically unlimited.
Vladimir Shendorov, ” In your opinion, the speed of light has a different value not because of the mechanical properties of the propagation medium, but because of the change in time.” You are one of those thinkers who likes to argue with themselves. The above quote from you has nothing to do with me. the rate of time passing on the surface of a neutron star is determined from the spectra of known elements. This phenomenon is known as gravitational redshift. Read more.

TIME is one of the many number systems that depends on the STANDARD of time.
In any part of the universe, TIME must be calculated strictly in accordance with the standard.
If you want to calculate the TIME in each place differently… you need to invent a separate time standard for each place in the universe.
The first person to introduce the concept of “local time” was Hendrik Anton Lorenz. He did this between 1892 and 1895, developing his theory of the absolutely stationary ether, which was supposed to explain the negative results of experiments on the detection of absolute motion. His theory was valid only in the first order of smallness with respect to v/c, where v is the speed of motion and c is the speed of light. Trying to extend his theory to all orders of smallness, he introduced Lorentz transformations (the name was not invented by him), but made some mistakes, which were later corrected by Jules Henri Poincare.
It's just that time is just as subject to the forces of global gravity as absolutely all objects in the universe. This theory was put forward by Albert Einstein himself, having gained practical proof with the development of technology. From his statements, it followed that matter attracts the flow of time, slowing it down the more strongly, the greater the gravitational field it has. Simply put, the more massive an object is, the slower time passes in its vicinity.
