What exactly is a black hole? Is it possible to travel through time and space?

Second floor. According to e=mc2 and special relativity, no object can reach the speed of light.

Only light or other waves with no intrinsic mass can reach the speed of light.

You can go to the Internet and search for things about this direction, there are a lot of them. Generally speaking, a black hole is a very massive substance. Can I travel through time and space, I don't know, and many scientists want to know this?

It was formed after the super-large planet**, and as for whether it can use black holes to travel through time and space, no one can answer yet, because no one can enter it yet.

It is the last product of life on stars. According to Einstein's theory, when the velocity exceeds the beam, it is the time when the relative time stops, and time travels backwards, thus time traveling.

The existence of black holes has little to do with human travel through time and space. Black holes are the real existence of the objective world, and traveling through time and space is a kind of human idea, which is a beautiful idea, but it will never be realized.

A black hole is a material formed by a star of a certain size that collapses and contracts after a long process of nucleation reaction. Although invisible, it is a part of cosmic space like a star. Because black holes occupy a certain amount of space, they are made up of dark matter, which is different from matter that is made up of molecules and atoms.

Although invisible, it is also material. In fact, the space occupied by the protostars has a huge mass and gravitational force, and any tangible and intangible light, including light, entering the black hole will disappear and become without a trace. The original matter has been transformed into negative neutrons smaller than atoms that are absorbed or adsorbed by the center of the black hole and become part of the matter at the center of the black hole.

In fact, the black hole is also a celestial body in the universe, which is formed by the collapse of massive stars after the fuel is exhausted, and the mass and gravitational force are so large that even the light will be swallowed up, so the black hole can be said to be "pitch black"! Since black holes are celestial bodies with a lot of mass gravity, falling into a black hole is only death, and the huge tidal gravity will tear apart everything that comes close!

The development of time is always forward, there is no regression, the so-called time travel back to the past, that is a human fantasy, there is no evidence that it is possible to return to the past or the future. As for space jumps, there may be wormholes that change the distance between two places, but this is unlikely to happen on a black hole, because a black hole is a real sphere, not a hole. It is impossible for a person to be sucked into a black hole, just like a person falling from outer space to the earth, both of which are hitting a sphere, but the speed of the collision is different, one is a faster destruction, and the other is a slower destruction.

There is no such thing as traveling through time and space in reality, only in science fiction and movies.

There is a possibility. Very scary existence. The black hole is a swirl-shaped, and this hole is very dark, many people are afraid to go around this hole, this hole has a great attraction.

It doesn't take people across. A black hole is a very destructive being. My understanding is that the formation of black holes is very difficult, and it takes a very strong force, and the inside of the black hole will produce a strong **, which will cause a lot of damage.

No, black holes are a special phenomenon in the universe that can travel through it, this is a conjecture that has not been confirmed, and I understand that it is Einstein's conjecture.

There are three major types of black holes, namely giant black holes, large black holes, and micro black holes. Under certain conditions, black holes may really help humans travel through time and space, return to the past, and change the future. As we all know, in the observable universe, black holes can be called a terrifying celestial body that terrifies human beings and even makes all civilizations "restless".

The power of black holes, presumably needless to say. The black hole has an incomparably large gravitational pull, which can make all matter unable to escape its claws; Even photons and neutron stars are not exempt from vulgarity.

Recently, NASA announced that they had discovered a "miniature black hole" in each of the two corners of the solar system, which caused panic among many people. However, there really is nothing to be afraid of; Why? It all starts with the types of black holes.

There are three main types of black holes:

The first type is "giant black holes", which are generally thousands of times the diameter of the sun, or even tens of thousands of times larger; They are generally the "dimensional disorder" phenomenon caused by the huge space-time expansion at the singularity**, resulting in creations, for example, silver core black holes; The second category is "large black holes". Large black holes are the most common black holes in the universe;

This kind of black hole will be formed after the massive star enters old age and gradually collapses, and in 2017, NASA captured the "black hole image" of this kind of large black hole; The third category is "miniature black holes". They may come from the collision of neutron stars, or they may come from particle friction;

This kind of black hole is generally very small, and it is not even comparable to some meteorites and asteroids. Therefore, they do not have much destructive power. These two miniature black holes in the inner solar system are only the size of grapes.

Wayne, a professor at the Department of Astronomy at Columbia University, believes that there is a "wormhole" hidden in the center of the event horizon of the black hole. The wormhole is a bridge connecting dimensions, with the help of which human beings can travel to other parallel universes, and even change the past and reverse the future.
