Cosmos - Black Hole


A Black Hole is not a hole in the real sense. It's a black cosmic body. There exists a black cosmic body at the center of every galaxy in our Universe. The present radius of the black cosmic body of the Milky Way Galaxy is 6.94671446 x 108 km. Its present surface gravity is 278.446 km/sec2, which is greater than that of the Earth by over 28000 times. The orbital velocity presently required to orbit around the surface of this black cosmic body is 4.39805 x 105 km/sec, which is greater than the velocity of light. Therefore, the light rays passing through the vicinity of the black cosmic body with a velocity of around 3 x 105 km/sec are accelerated by the latter's huge gravitational pull that causes their revolution around it.

The escape velocity of a particle from the surface of the black cosmic body of the Milky Way Galaxy is 6.21978352 x 105 km/sec. Therefore, the light rays which traverse directly to the black cosmic body fall on it with accelerated velocity and bounce back to fall on it again. The bouncing act of a light ray on the black cosmic body is a continuous process like that of a perfectly elastic ball on a perfectly elastic surface. Since this escape velocity is larger than the velocity of light, no light rays can escape from the surface of the black cosmic body. In fact, no particle having velocity of less than 6.21978352 x 105 km/sec can escape from its surface. Since no light ray can escape from the surface of the black cosmic body, no light ray presently reaches our eyes from it. So it looks dark against a background of dark space. In fact, it looks like a hole because every free particle on its surface orbit around it at a velocity of 4.39805 x 105 km/sec. Therefore, we can not even see the existence of the black cosmic body at the center of the galaxy through our telescopes.
