Einstein created the Special Theory of Relativity and claimed that:
"For speeds exceeding the speed of light, our reasoning is meaningless. By the way, we will be convinced by the following considerations that in our theory, the speed of light physically plays the role of infinitely high speed".
This idea of Einstein's is wrong because it leads to conclusions that contradict reality.
The expression, " motion with infinitely great speed" is incorrect. There is a phenomenon that modern science calls this, but it is not speed. The essence of this phenomenon is simultaneous mutual action between whole things. In Slavic Bulgarian, in Cyrillic, it is written as follows: ВЗАИМНОДЕЙСТВИЕ.
This is one word, and it is different from the Bulgarian word .ВЗАИМОДЕЙСТВИЕ
I suggest, in English writing, to use the word .MUTUALISACTION
