Can you come out of a black hole again, has anyone ever entered a black hole?

If you enter a black hole, you won't come out again. At its core, a black hole is a high-density star that can suck cosmic matter into it and bind it. So, if you enter a black hole, you won't come out again.

Of course, there are also those who believe that black holes are a window to another space, however, there is no evidence or basis to support this claim.

In general, a black hole is a cosmic astronomical term that means the final state of a star. The reason why it is called a "black hole" is because astronomers have deduced a cosmic phenomenon based on Einstein's theory of relativity that cannot be directly observed or observed with current scientific methods. Astronomical scientists speculate that there is such a galaxy in the vast universe that even light cannot escape its gravitational pull, so that it does not reflect or emit any visible light, and is as black as the cosmic background, hence the name.

According to the existing knowledge of physics, astronomy and general relativity, since there is a star with strong gravity such as a black hole in the universe, there must be a star opposite to it, so that objects attracted by the gravitational pull of the black hole can escape from the black hole. According to the British scientist Stephen Hawking, black holes are not all for absorption and do not radiate outward at all. Stephen Hawking argues that even a black hole, according to theories such as temperature radiation, should radiate energy to a region that is cooler than it.

Therefore, it is generally believed that some protons may also be radiated by the black hole after entering the black hole.

Hello, Xiaohe is honored to answer for you, has anyone ever been in a black hole? Only the astronaut Cooper in the movie "Interstellar" has had this experience.

What happens when an astronaut falls into a black hole, is it immortal or instantaneous? The gravitational pull of black holes is so strong that astronauts will be pulled into spaghetti and then shredded into elementary particles and even strings of energy? In fact, reality is more bizarre than fantasy, of course, everything can only stay in the stage of theoretical speculation, after all, there is still no human experience of falling into a black hole.

Scientists speculate that the moment the astronaut falls into a black hole, for him, the entire universe will be split in two, and the astronaut himself will forever advance towards the singularity. To the outside world, he seems to be a monument at the edge of the horizon, maintaining a posture of advancing towards the center of the black hole, never disappearing. In Star Trek, Cooper fell into a black hole and was not torn apart, because he fell into an ancient and gentle black hole with a mass 100 million times that of Earth.

There is a bare singularity through which matter can enter the four-dimensional space or the new universe, and the singularity of a black hole is a node of the world and space-time, with an ultra-small volume and infinite curvature of space. Cooper had actually been torn apart, but that moment was eternal, and he could live forever until the end of the universe. Finally, we conclude that the astronaut can live forever at the moment of falling into the black hole, he changes from three dimensions to two dimensions and is preserved at the boundary of the black hole, if he is lucky enough to fall into the black hole singularity, then he can be said to have entered a new world, and what appears in his eyes may be a four-dimensional space or a new universe.

Summary. For the time being, no one has ever entered a black hole, because the black hole is the most mysterious substance in the universe, more unfathomable than the sun, the depth is beyond our imagination, it is a super gravitational field, due to the infinite attraction of gravity, even if a spacecraft has the ability to enter, it is impossible to escape from the black hole, so no one has entered the black hole for the time being, but scientists are trying to study how to enter the black hole and explore its mysteries.

Has anyone ever been in a black hole?

For the time being, no one has ever entered a black hole, because the black hole is the most mysterious substance in the universe, more unfathomable than the sun, the depth is beyond our imagination, it is a super gravitational field, due to the infinite attraction of gravity, even if a spacecraft has the ability to enter, it is impossible to escape from the black hole, so no one has entered the black hole for the time being, but scientists are trying to study how to enter the black hole and explore its mysteries.

No one has ever been in a black hole for a while, because a black hole is an extremely complex celestial body that has a physically infinite gravitational pull that is enough to suck an object into it so that it cannot leave again. Because its gravitational pull is so strong, even light cannot escape its influence, therefore, the inside of the black hole is pitch black and nothing can enter. Aside from the researchers' use of powerful computer simulations, no scientists can enter a black hole for the time being.
