Black holes can swallow stars

There are many unsolved riddles in the vast universe, including the impressive "black holes".

In the eyes of scientists, black holes are like a gourmand that can swallow all matter, our understanding of black holes is only on the surface, although scientists have been exploring the path of black holes, our understanding of their interior is still very little, "black holes" is like a universe of The "black hole" is like a "big monster" in the universe, we can not do anything about it.

Since black holes are as scary as they are said to be, and can swallow some matter, where does the swallowed matter go?

The "master" of the universe, the black hole

The discovery of the black hole originated from the modern general theory of relativity, which is a kind of celestial body existing in the universe. There are countless objects in the universe, and their masses vary greatly. In the universe, whoever has the largest mass can be the rightful "master of the stars", and the mass of a black hole is enough to shock all celestial bodies.

Why does a black hole have such a large mass? It turns out that this is due to the singularity at the center of the black hole, which is a very powerful mass with a very small volume, so its density is unimaginable.

Any object in the universe encountering a black hole will only be swallowed, imagine who can defeat a monster of infinitely small volume and infinitely high density? So even a star, when it encounters a black hole, will only fall to the fate of being swallowed.

From what we currently know about the universe, black holes are undoubtedly the most powerful objects in the universe. From Newton's law of gravity, we know that gravity is related to the mass and distance of an object, so even if the volume of a black hole is small, it has a mass that all celestial bodies are in awe of.

As a result, the gravitational force generated by a black hole is also very strong, and with it comes a terrible ability to devour.

Do you know what it is like when a star is swallowed by a black hole? If an "unlucky" star falls into a black hole, it is subjected to tidal forces and stretched, like spaghetti, until it can no longer maintain its density and pressure.

The fusion reactions inside will gradually stop until it completely disintegrates, and the disintegrated material will either be sucked into the black hole or ejected. It takes millions of years for a star to form, but only a few hours for a black hole to disintegrate, so it is clear that the dominance of black holes is well deserved.

The origin of black holes

How did such a super scary monster come about? Scientists have several theories about the origin of black holes.

The general theory is that black holes arise from supernova explosions, which occur when some stars in the universe die and explode, leaving behind a core whose mass determines where it will end up. If the core is more than three times the mass of the Sun, then it forms a black hole.

But this is not the only way a black hole is formed. According to scientists, there is another way to form a black hole, and that is the merger of neutron stars.

If a star explodes and leaves a core that is between 1.44 and 3 times the mass of the Sun, then it will form a neutron star, and if these neutron stars meet the right companion will be close to each other until the merger, the mass fusion gradually increased, can also eventually evolve into a black hole.

These are the principles of the formation of stellar black holes, there are more mysterious black holes in the universe, that is, the original black hole. The existence of such black holes should be very old, their creation can be traced back to the Big Bang period, their volume is almost negligible, while the density is infinite.

At the beginning of the Big Bang, it was characterized by a very small volume and the concentration of all matter in a single point, and this was the best place for the formation of black holes.

However, the original black hole is too small to be observed by the naked eye, and we can only understand it indirectly by observing the huge gravitational vortex that it creates by swallowing objects.

Where do they go?

Since a black hole can swallow all objects in the universe, where do the objects swallowed by it go in the end?

Scientists have conducted a special study on this. Although the size of a black hole is too small for us to observe with the naked eye, the process of black hole swallowing can be observed. So much matter is swallowed by a black hole, why is the change it undergoes not obvious? How does it digest this matter?

In 1972, Stephen Hawking discovered that a black hole is not the only function of devouring, instead, it will also emit energy outward, scientists speculate that this may be the opposite of a "white hole".

If a black hole is specialized in absorbing matter and energy, then the white hole is to disperse these substances, so even though the black hole swallowed a very large amount of matter, but still no significant changes, because its internal balance with the white hole in the role, but this idea is only scientists' speculation, and has not been substantiated.

Another view is that a black hole is a space-time tunnel, and the matter caught in the black hole will travel to another space-time, which is what we call a parallel universe, and the black hole is using its strong gravitational force to involve the matter in another parallel space, but there is no direct evidence to prove this idea.

Where do the things swallowed by black holes go? All the current explanations are only speculations of scientists, and human cognition is limited by time and tools, so we cannot fully understand all the mysteries of the universe.

But from all the speculations, we can conclude that a black hole is indeed a very powerful object, and the energy and effects it produces should not be underestimated, and the reason why we are afraid of black holes is that we do not know enough about it, and I believe that in the future, higher levels of technology will tell us the answers to these questions.
