Interpretation of the Separation of Center of Mass of Lens Inversion and Hot Gas in Collision Galaxies

This article first reviews the phenomenon of separation of the mass center of gravitational lens in a collision galaxy from the mass distribution center of the hot gas as the main substance, and deeply analyzes the meaning of it: the hot gas as the main substance does not contribute to the gravitational lens, that is, the hot gas does not bend the light around it, nor does it bend the space-time around it. In the correct explanation: When visible light passes by the massive luminous planet, it is affected by the continuous electromagnetic waves emitted by the massive luminous planet, forming an arc curve around the massive luminous planet, just like gravitational curve. At this time, people form the reason why gravitational curved light. Then this article proposes an explanation of the same frequency mutual circumference of light bend, indicating that when light passes by the massive luminous planet, the degree of bending of light is proportional to the brightness of the massive luminous planet, and inversely proportional to the shortest distance between visible light and the center of the planet. This article believes that there is no dark matter in collision galaxies, and the space-time view of general relativity is worth discussing. Finally, this article explains that there is a slight non-distance redshift in lens galaxies. At this time, you should pay attention to when calculating the distance of galaxies using redshifts.
