Will the universe one day be completely swallowed by a black hole?

Maybe it's possible, but I don't think it's going to happen at least not during your lifetime.

There's a magical substance in the universe called dark energy, which makes up 70 percent of the matter in the universe, and it does the exact opposite of what a black hole does.

It's a powerful repulsion force between the stars, which makes the universe expand, but thankfully, there's a substance in the universe called dark matter, which deflects light and has a strong gravitational pull that keeps the stars in touch with each other. And the formation of black holes is very difficult After the average star dies, it will become a white dwarf It is not only stars that can evolve into black holes If the earth is strongly compressed, it will also become a black hole But the density of black holes is very high The earth can only become a new black hole if it is compressed to the size of a soybean And black holes cannot never stop devouring matter When the matter he swallows reaches a certain limit, it will be spit out again So you get it I hope it helps you That's all I know Add a few points!!

It is possible. There are theories that the universe is such a cycle. But it's just speculation. It can't be proven.

In the distant future, it is possible that when stars run out of energy, they will eventually become black holes.

No, there is more than one black hole, and each large galaxy has a star similar to a black hole, because the formation of galaxies is due to these stars, and the role of black holes is to limit the stars in the galaxy to a certain range, so as to maintain the balance of the universe!

Black holes don't swallow everything. It will not swallow the universe, because many scientists believe that there is an upper limit to the engulfing ability of black holes, and when this upper limit is reached, ** will occur, and then an infinite loop, which is also the cycle of the universe.

No, there are things that can be swallowed, there are things that can't swallow black holes, and I don't think the universe will be swallowed. Because the universe is really big.

Black holes can swallow everything, because black holes are very big, and people don't know much about black holes, I think they will swallow the universe.

I think a black hole can swallow everything, so I think if it could, it would eventually swallow the universe as well.

For a black hole to completely swallow a sun, it also needs to look at its own mass.

If it's a stellar black hole, it usually takes longer than we think to see the Sun. Because the mass of the Sun is about the same as that of a stellar black hole, when a black hole wants to devour the Sun, it needs to slowly circulate around the Sun.

Then, in contact, the black hole slowly swallows the atmosphere on the surface of the Sun. It then slowly "sucks out" the heat from the sun's surface and the sunspots on its surface.

At the same time, the mass of the black hole gradually increases over time. In this case, it would take hundreds of millions or even billions of years for a black hole to devour a sun!

Of course, there are also cases where black holes collide with each other as they move with the sun. In this case, the sun simply can't hit the black hole. The sun is scattered by a black hole.

In this case, it will be extremely easy because the sun is scattered and the black hole is swallowed. It only takes tens of thousands or hundreds of thousands of years to devour the sun!

If it were a galactic black hole, the situation would be very different if it engulfed the sun. The mass of galactic black holes is simply not as good as that of stellar black holes. A galactic black hole would be hundreds of thousands or even hundreds of millions of times larger than the Sun.

It's like the supermassive black hole at the center of our galaxy, which is 4.31 million times more massive than the Sun and about 44 million kilometers in diameter.

In this case, a galaxy-sized black hole could easily swallow a single sun. Before the sun is fully attracted, it is sucked away by the black hole's enormous gravitational pull and then turned into many fragments that are swallowed up.

Scientists are said to have observed black holes devouring the sun. Since the black hole is much larger than the sun, within a few years, the sun will be completely swallowed by the black hole, and the scene is spectacular.

The universe cannot be swallowed up by black holes because the universe is constantly expanding.

No. Because the universe is infinite, it cannot be swallowed by a single celestial body, and black holes cannot swallow the entire universe.

A black hole cannot swallow the universe, but there are countless black holes in the universe, and they are still spreading, and even the universe may be swallowed when a critical point is reached.

As the most mysterious celestial body in the universe, black holes are infinitely small in size and infinitely dense. There is an interface around it, and anything that crosses it will never try to escape, even the fastest light in the universe.

As you approach a black hole, you experience the extreme gravitational pull of the black hole. Your body will experience extreme acceleration as you will experience unbearable forces.

As you get closer and closer to the black hole, the acceleration reaches a limit.

When you reach the horizon of a black hole. Not even light from your body can escape the gravitational pull of a black hole.

Your body will be stretched, and your body will look like a stretched noodle before reaching the horizon. This is due to the effect of redshift.

When you pass through the event horizon, there's no way back. You can't come back after passing through the horizon because to do that, you have to gain infinite speed, which is practically impossible. When you reach the center of a black hole known as the singularity, you end up dying from the immense gravitational pull.

This is the end of life.

In fact, black holes are also a kind of celestial body, which can be seen as another way of existence of stars, so there should be no essential difference between the earth being swallowed by a black hole and being swallowed by the sun, both of which will become a part of each other, very similar to an asteroid hitting the earth!

Some people think that being swallowed by a black hole does not mean that it must be dead, one is because of the particularity of black holes, its properties are very different from ordinary stars, of course, our current description of the nature of black holes is basically based on theoretical speculation.

Another reason is all kinds of science fiction movies and speculations about black holes, such as the entrance to different space-time or different universes, or the entrance to high-dimensional space!

For example, in the science fiction movie "Interstellar", there is a plot description of crossing the black hole, after entering the black hole, he did not die, but entered the five-dimensional space-time, a completely different world from our four-dimensional space-time, and can return to our four-dimensional space-time.

As the black hole slowly approaches the Earth, a lot of anomalies occur on the Earth. First it sucks up the atmosphere, and it causes the atmosphere to spin like a tornado into a black hole. The closer the black hole gets, the stronger the impact on the Earth, and you can feel a force pull you away from the Earth and disappear with a thud.

It won't be long before the gravitational pull of the black hole tears the Earth apart. This force completely disintegrated the earth, tearing all matter to pieces, and eventually all matter was swallowed by it.

So we don't have to worry about the black hole swallowing up, because after all, after 10 million years of black holes, when they come to the vicinity of the earth, human beings may cease to exist. Compared with black holes, the increasingly serious problems of resource waste, garbage pollution and global warming are more worthy of our vigilance, after all, there is only one earth, cherish the earth's environment, and low-carbon life starts from you and me.

The universe will go back to its original state, because the original appearance of the universe is that nothing is dark and makes people feel so lonely.

Then the universe will be dark, all the planets will cease to exist, and there will be no life at all.

When the time comes, all the substances will gather together, the mass will become larger, and the substances will continue to concentrate together, and perhaps after a period of time, the large ** will occur again, and these substances will be separated again.

All black holes swallow everything, in fact, the most bullish black holes swallow other black holes. The only black hole left is the universe.
