Everything that is written here is not at all a popular scientific presentation of some generally accepted scientific views or original ideas discussed in the scientific world. In some ways, it's even the opposite. Here is a unique analysis of interesting comments collected on various forums where popular scientific materials related to the provisions of the theory of relativity are discussed. This may seem strange to some, but among the many comments there are some that in their value can compete with the material being discussed. And it’s a shame that they are lost without a trace on the Internet. Everything presented here is an attempt to kind of combine into one whole the most interesting thoughts and ideas expressed in the comments.
