Anonymous users2024-02-04<> if a black hole is far away from the sun, it will never be able to swallow the sun;
If it is close, it is still a supermassive black hole, and it will not be long before it can swallow the sun;
If they get closer, the average black hole will strip the sun of its material little by little until the sun disappears, a process that may take tens of thousands of years.
If it were a miniature black hole, it would never have been possible to swallow the sun. Scientists have discovered that there can be no black holes in the current solar system, which means that the sun will not be swallowed by black holes now.

Anonymous users2024-02-03A black hole is a celestial body that can devour everything around it because of its strong gravitational pull. The black hole can be described as a terrifying "giant" in the universe that everyone talks about, and some people jokingly call it a "rogue leader" in space.
There is no other reason than the fact that black holes have a strong ability to attract. It is said that he can open his mouth and devour all celestial bodies and matter that are or will approach him, even the "light" that is known for its speed.
Black holes are one of the celestial bodies we know of, and they are by far the largest objects with average mass and volume. According to today's scientific theory, the mass of black holes is almost "unlimited". The ultimate mass of a star, as has now been concluded, is two hundred and forty-seven times that of the Sun.
And we can often find black holes with masses tens of thousands of times more than the sun: it is precisely because of the terrifying "suction" that its mass has expanded to such a terrifying state. Generally speaking, after the death of a star, it becomes a "supernova"; If the supernova fails again, it becomes a black hole:
That said, there is also a good chance that our sun will become a black hole billions of years from now.
The reason why black holes can devour everything is, of course, because of the gravitational pull it has. According to the law of gravitation, the greater the mass of matter, the greater the gravitational force; Since the mass of the black hole tends to be infinite, its gravitational pull has also reached an immeasurable point.
It is speculated that the gravitational pull of a black hole has reached the second cosmic velocity, which is higher than the limit of the first cosmic velocity: the speed of light. According to Einstein's special theory of relativity, the limit of matter is the speed of light. So black holes can devour everything.
However, it is worth mentioning that in general relativity, gravity is a kind of curvature of space-time: this represents the vicinity of the black hole, and even the center of the black hole, which is likely to allow us to achieve such a magical operation as "space-time travel". Some people say that after entering a black hole, it is a "wormhole".

Anonymous users2024-02-02<>Hello dear, I'm glad to answer for you, black holes can devour the sun. Black holes are all-devouring beings in the universe, and even light walking around them cannot escape the fate of being devoured, and the mass of black holes is very large, the smallest ones are three times larger than the sun. Different black holes need different limb sources to devour the sun, depending on the mass of the black hole.
In 1916, the German astronomer Karl Schwarzschild calculated a vacuum solution of Einstein's field equation, which showed that if the actual radius of a static spherically symmetric star is less than a fixed value, a strange phenomenon will occur around it, that is, there is an interface - "horizon", once Sakura Han enters this interface, even light cannot escape.

Anonymous users2024-02-01Yes, theoretically, a black hole can swallow the sun, and because the gravitational pull of the black hole is extremely strong, it can cause the sun to be gradually swallowed by the black hole. However, it is important to note that the Sun is quite far away from us, and black holes are not visible everywhere, so it is difficult for people to observe such phenomena directly. A black hole is a special type of celestial body that is formed by an extremely large star that exceeds the Chandrasekhar limit of a certain mass, with a huge mass, a very small body, and a surface escape speed exceeding the speed of light.
Its gravitational pull is irresistible to all matter, including the sun. If the sun is engulfed by a black hole, then as the sun approaches the black hole, it will be pulled into a long strip until it eventually disappears inside the black hole. When a black hole swallows matter, it produces very strong gravitational waves, which propagate outward, so gravitational wave detectors can be used to detect the situation of the black hole swallowing the sun and other celestial bodies.
Since black holes are the result of the evolution of massive stars, due to gravitational attraction, f=gmm r 2, their ability to attract objects is so powerful that even light cannot escape the clutches of black holes. Stars are also made of basic matter, and black holes can of course swallow stars, but this process is very slow, called black hole accretion, and at the same time release strong rays such as x and r. >>>More

If the sun collapses into a black hole in the future, Mercury, Venus and other celestial bodies close to the sun will be swallowed up, and the earth will definitely not escape, the high temperature will first evaporate all the earth's seawater, the atmosphere will be sucked away, all life will be destroyed, and the earth may be torn apart, or swallowed up, becoming part of the sun's black hole. >>>More
The gravitational field of a black hole is so strong that any matter that comes near it will be absorbed by it, and even light that is as fast as 300,000 kilometers per second cannot escape when it reaches the edge of its event horizon, so if the black hole is in a place where it is extremely rich in matter, its mass can grow rapidly. Almost all galaxies have a massive black hole at the center, and it is constantly eating away at the black hole's material, so will this black hole eventually eat the entire galaxy? >>>More
At first, a large amount of gas (mostly hydrogen) is attracted by its own gravity and collapses into a star, and when it collapses, the gas atoms collide more and more frequently (and at higher speeds), making the gas hotter and higher, and the molecular thermal motion intensifies, and the hydrogen atoms collide at extremely high speeds, so that when they collide, they do not bounce off but converge to form helium. Like the hydrogen bomb**, it releases a lot of heat, and the extremely high temperature increases the pressure of the gas to reach the equilibrium point with gravity (that is, it is neither affected by gravity and continues to collapse, nor expands outward due to air pressure), however, with the consumption of fuel, the heat that can be provided is less and less, and gradually it cannot resist gravity, so the star begins to continue to collapse (don't think that the more initial fuel of the star, the longer it will live, because the greater the mass of the star, the greater the gravitational force, the more heat required to fight gravity, the faster it will be consumed, Our sun can live for another 5 billion years, and some big stars can consume the same amount of heat in 100 million years). If the mass of a star is less than the Chandrasekhar limit (such as the Sun, the Chandrasekhar limit is one and a half times the mass of the Sun, below the Chandrasekhar limit it will not collapse into a black hole, and if it is exceeded, it will. >>>More
