If gravity is stronger, most people can't stand it. It's better to leave quickly. When the gravity reaches 1000g, trees will be crushed by their own weight;
65,438+0,000,000 g, the stone is broken. Everything we are familiar with cannot survive. Only light looks straight-basically straight in terms of human resolution. When gravity reaches1000 billion g, something incredible happens: the light beam that was originally directed at the sky is obviously bent. If gravity continues to increase, light will bend so much that it will return to the ground in reverse. Since even light can't escape the bondage of gravity, nothing else can escape. If anyone accidentally approaches this gravitational range at this time, they will sink in and never get out. A celestial body with such a strong gravity will be a monster that can only swallow but not spit, a bottomless black hole.
Black holes are neither black nor empty. It is a real celestial body. If we can have special immunity and enter the gravitational range of a black hole without being torn, we will see that the inside of the black hole is not dark: the inescapable light goes around inside, and there are bright lights everywhere. ?
The basic definition of a black hole is that it is a celestial body with a closed horizon. Foreign matter and radiation can enter the horizon, but nothing can go out in the horizon. This horizon is the boundary of the black hole. If we can observe calmly from the outside, we will see an absolute darkness with boundaries, exactly like a hole. ?
