You know black holes suck things in. You imagine that a black hole is a vortex. . . If the black hole is divided into southeast and northwest, the east and west sides of the vortex are also the places where the gravity of the black hole pulls all the space materials in, and the north and south are sprayed. Don't think that black holes only suck and don't spray. In fact, the north-south spray is not a real spray, because what is sucked into the black hole will not come out again, but those. . . Matter inhaled from the east and west but not yet reaching the horizon is pushed by gravity to erupt to the north and south. . .
Because it will generate a lot of energy when it is sucked in, the black hole is constantly devouring it. The matter sucked away is as big as a star, constantly resisting the ultimate fate with its own gravity, but it is still in vain. After all, the gravity of black holes will still tear them apart. When a star (in fact, whether it is a star or not, I take a star because of its relatively large energy, in fact, all substances are the same) is pulled around the horizon, at this time the star has not yet formed, and it has been pulled around the black hole for a long time and has not yet entered the horizon.
I don't know if you understand. . . .
Or imagine a pig that will never get enough to eat. He can eat many times more than himself, but he only has one bite, so it is impossible to swallow an elephant in a short time, but food will always be squeezed into his mouth indefinitely. Although the gravity of your stomach is very large and infinite, you still have to go through your mouth to get into your stomach, so if you can't swallow it at once, you will be squeezed out of your face. . . However, food still keeps coming and even being pushed into the stomach, but it is the mouth that eats, not the stomach, so even if food accumulates in the stomach, it will not be sucked in. .

white hole
White hole is a physical concept, which has not been proved. Infer from the present physical knowledge and foundation. . . Everything is the opposite of a black hole. If the black hole keeps sucking, gravity will distort the space and suck in all the light traveling in a straight line. Then the white hole is completely reversed, and it keeps spraying, so that the light can't enter the extended space with strong eruption force (just like you are swimming and the swimming pool keeps stretching, no matter how fast you swim, you can't reach the finish line, and every step before swimming becomes more and more tired, because the closer you get to the finish line, the longer the extension force is, and the speed remains the same, so you will lose in the end. . . )
Physicists do not rule out that the other end of the black hole is a white hole, but the space where human beings are now cannot be detected. . . In other words, the white hole should be outside our four-dimensional space. . . If you have the ability to go to multidimensional space, you can find it. White holes, wormholes and cosmic strings are all in another space. . . )
The picture is the concept of a black hole. . .
