In doing this work, I try to better understand and understand relativity by giving it another form that better describes the relation between the energy of a particle and the speed of light (C) and I find a new parameter of time that I use it to explain deeper my theorem which is based on this newly exploiting aspect through a development of a special mathematical concept that gave me specific access to develop and bring out the energy theorem. I would also say that the theorem is a new mathematical and physical structure that is both linking and appropriate the C remains the same my concept just explained the phenomena that we can find them in far galaxies or even in our galaxy, as, for example, the black hole because at the level of these...
