6 Knowledges About Black Hole
Black holes are not black
The reason why it is called a black hole is because light cannot escape my "devil's grasp", so it looks completely dark on the surface, but this does not mean that the black hole is black.
Black holes can be transparent
Around the black hole, the space-time distortion is very large. Although part of the light emitted by the stars will be absorbed by me, the other part of the light will bypass me through the curved space and reach the earth. As a result, the starry sky behind me is observed. Like it doesn't exist!
The special feature of black holes is their small size
Black holes have such weird characteristics not because of their mass, but because of their small size. A huge mass is stuffed into a very small volume to create a black hole.
The destruction of a black hole is an explosion
The loss of energy will result in a loss of quality. It shows that while the black hole gradually consumes energy, it also represents the loss of mass, and its temperature will get higher and higher. Small black holes radiate energy at extremely high speeds until the black hole explodes.
The black hole itself has rotating and non-rotating
Like other stellar bodies, black holes sometimes keep rotating, and are divided into "non-rotating black holes" and "rotating black holes", while rotating black holes are called Kerr black holes.
Black hole gravitational equivalent
After the sun is "squeezed" into a black hole, the external gravitational effect will not change. In other words, when you blindfold the earth, she will never notice whether the sun or black hole is affecting her movement.
