The essence of black holes
Black holes are really mysterious? Please stop myths about black holes, what dark matter , light cannot escape, time will be distorted, etc. I wanted to understand things many years ago, but why haven't I seen any reliable discussion. I have to speak out today. A black hole is like other stars. It is not black and not a hole. Its essence is "big'
. Its size is relative. The natural gravity of a star with a huge mass in an area is also relatively huge. It is so big that the nearby light
lines can be ignored at all. There is no nearby luminous center to illuminate it, and a black hole is formed. It is like a huge room without light, mobile phone The light is negligible and the room seems mysterious.
The gravity of a black hole is a protector for the earth. Maintain a safe distance, reach a balance, and form a galaxy. Huge black holes attract collisions with stars in non-safe areas, so there will be many collision marks on the black holes. Black holes are variable. When they encounter a large enough luminous object to illuminate the black hole, it will be bright.
