Cherenkov Radiation of Gravitational Waves

Zhi Cheng

Abstract


If the velocity of gravitational waves is less than the speed of light, the velocity of mass motion may exceed the velocity of gravitational waves. This will cause Cherenkov-like radiation similar to electromagnetic interaction. The Cherenkov-like radiation of gravitational waves will produce a relatively specific observable effect. Due to the concentrated release of energy, the easiest to observe is that a large number of photons are radiated from the Cherenkov-like radiation source to form optical effects of high intensity and relatively special shapes. The speed of gravitational waves is less than the speed of light, because the compression of space and time by very large masses causes the gravitational waves to travel less in the masses than the speed of light. The mass of the material itself is not affected by this space-time compression. Thus, under certain conditions, the velocity of the mass of matter exceeds the velocity of the gravitational wave, forming a Cherenkov-like effect. A typical example is the aura of special structures formed by the supernova explosion. Among them, the supernova 1987A has been in existence for more than 30 years. After several years of the explosion, through the observation of the high-resolution Hubble telescope, it was found that the supernova 1987A showed two distinct auras in its explosion direction. There are many explanations for how these halos are formed. This paper points out that the formation of the two halos of the supernova 1987A is related to the propagation of gravitational waves in the mass of matter. Due to the very high mass density of the supernova explosion area, the space-time compression effect is very obvious, which will cause the gravitational wave to have a wave speed less than the speed of light. The material ejected by the supernova after exploding is close to the speed of light, and it is easy to exceed the velocity of gravitational waves propagating in the cosmic fluid around the supernova explosion, which will form the shock wave effect of gravitational waves. The Cherenkov effect of gravitational waves can also be used to explain the origin of high-intensity photon radiation in some galaxy centers. When the black hole in the center of the galaxy attracts the outer mass, the closer it is to the central black hole, the faster it moves. In the right position, the mass moves faster than the gravitational wave. The Cherenkov-like radiation of gravitational waves will be product. In addition, if there is a white hole, the energy is continuously released from the source of the white hole, which will also cause the mass ejection speed to exceed the speed of the gravitational wave, and thus produces the Cherenkov-like effect. Since the dynamic mechanism of the black hole and the white hole are different, by observing the Cherenkov-like effect of the center of the galaxy, it can effectively distinguish whether the center of the galaxy is a white hole or a black hole.
