Abstract

Albert Einstein proposed the special relativity under the condition that using light wave as the signal and the propagation velocity of light wave in vacuum is a constant. According to the special relativity, Albert Einstein concluded that the rest mass of photon is zero and the velocity of any matter could not exceed that of light. These conclusions are doubted by many experimental phenomenons. In this paper, the wave that could carry arbitrary signals was used to transfer information. Assuming the velocity of the wave is a constant, the parameters of matter motion was calculated with the Lorentz transform. The results show that rest mass of photon may be not zero, when the wave with a velocity exceeding that of light is used as the propagation carrier. And also, obtain the conclusion that the powerful gravitation would change the density distribution of photon in the universe. The light wave will change the direction of propagation according to the density distribution of photon. As a result, the route of light propagation will change too. Photons will be attracted into the black hole continually by its limitless attraction force. In addition, wave propagating though photons could not escape the gravitation of the black hole.
