It is also proposed that all sports with process sports consume energy. The propagation of photons and light waves is the top speed in the universe, it also consumes energy, and lists the energy consumption and compensation process of light. The description of the light phenomenon in the universe is just a speculation in this article. For some researchers, this may be an enlightening point of view.
