A black hole is a special type of star that forms after the death of a large star. After the nuclear energy of the big star is exhausted, it cannot resist its huge gravitational pull, and can only collapse indefinitely, forming a cosmic singularity with infinite density. The gravitational pull of a black hole is so strong that even light cannot escape from it.
Once anything enters the "event horizon" of a black hole, there is no turning back. However, modern quantum theory suggests that black holes can "evaporate" due to quantum fluctuations, so small black holes can disappear.
Black holes do not emit any electromagnetic waves, and the X-rays we see are only emitted by acceleration and compression before some matter is sucked into the black hole, and the detection of the black hole itself can only rely on gravity.
-
Electromagnetic waves are possible, but sound waves are not. Because there is no medium in the vicinity of the black hole where sound waves are present.
-
Everything can be absorbed.
Because it is a singularity, it is a very dense substance after the collapse of the center after the death of the planet, and a black hole material the size of a meter can only be pulled by 16 giant tugboats, and the gravitational pull is extremely strong.
However, X-rays are released at the same time as they are absorbed.
It also evaporates, releasing some particles.
So the black hole sucks and spits.
Even light, which is an extremely high-speed particle, can be absorbed.
-
Anything goes.
Sound waves are the form of medium vibration, and there must be a carrier for sound, and its carrier cannot escape the black hole.
-
Electromagnetic waves are fine, because light is also an electromagnetic wave. However, sound waves are not necessarily, because it is difficult to determine the medium of sound propagation around a black hole.
-
Yes. Everything can be absorbed.
Because it's a singularity, the gravitational pull is extremely strong.
However, X-rays are released at the same time as they are absorbed.
It also evaporates, releasing some particles.
The meeting of two black holes will indeed engulf.
-
Black holes are very dense, so the gravitational pull is high, and everything is attracted to it, so it cannot be directly observed.
If Mount Everest were to reach its density, it would be the size of a basketball.
-
I can suck it. But can one black hole suck up another? Isn't it true that whoever is older sucks the other?
-
As long as one can think of it, it can be sucked. It cannot be said to be accurate to suck, it is to bring into another state of existence. Including distortions in space-time. Everything in the three-dimensional world changes in time and space. It can be said to be a kind of channel for three-dimensional high-dimensional space-time.
-
It stands to reason that it can, but no one has confirmed it.
-
Yes, light is also a wave.
-
A lot of light, electromagnetic waves, etc. can be sucked in.
-
Yes, anything can be sucked, including black holes attracting black holes.
-
According to Stephen Hawking's theory of black holes, black holes can absorb all matter.
-
Light is electromagnetic waves.
Sound waves require a medium, which is not present in a vacuum. Logically, it should be possible.
Buaazhy is smaller than basketball.
-
Time included. Take a look at Sagan's book The Universe.

No one says black holes suck people. Black holes attract not just people, but all objects that orbit within the gravitational pull of the black hole, including light.
Black holes can suck because of the huge gravitational pull of black holes. And the huge gravitational pull is due to the huge density of the black hole matter. This density is unimaginable. Your finger-sized black hole material can be hundreds to tens of billions of tons.
If you take the mass of the Earth, which is about 6x10 21 tons, if you convert it into black hole matter, it is only 6x10 11 centimeters and 6x10 5 cubic meters, which is only 600,000 cubic meters.

A black hole cannot absorb a planet with the same mass.
Black hole is a kind of celestial body in the universe in the modern general theory of relativity, and the gravitational pull of the black hole is very large, so that the escape speed in the event horizon is greater than the speed of light, and it is a celestial object with a curvature of space-time that no light can escape from its event horizon.
In 1916, the German astronomer Carl 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 - "event horizon", once entering this interface, even light cannot escape.
This Bisson's value is called the Schwarzschild radius, and this "incredible celestial body" was named a "black hole" by the American physicist John Archibald Wheeler, which cannot be directly observed, but its existence and mass can be known indirectly, and its effects on other things can be observed. By emitting X-rays and "edge messages" of rays due to the acceleration caused by the gravitational pull of the black hole before the object is sucked in, it is possible to obtain the information that the black hole has several traces.
Artificial black holes
In March 2005, Brown University physics professor Horatina Stasi created the first "artificial black hole" on the earth, and the Brookhaven Laboratory in New York, USA, built the world's largest particle accelerator in the 20th century in 1998, colliding gold ions at close to the speed of light to create high-density matter.
The relatively heavy ion collider at the Brookhaven National Laboratory in New York can collide large atomic nucleons (such as gold nucleons) at nearly the speed of light, producing heat energy equivalent to 300 million times the surface temperature of the sun.
The above internal brightness is also available for reference: Encyclopedia - Black Hole.
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
Black holes were first calculated by German mathematician Carl Schwarzschild, in the black hole around anything whether it is signal, light or matter can not escape, space-time here has become a bottomless pit, such a place that cannot be seen, touched or detected is called a black hole.
Light is an electromagnetic wave, it has no mass, and it is precisely because it has no mass, that it can reach the speed of light, and the higher the velocity of a matter with mass, the mass will increase (extremely high velocity), and increasing its speed will require more energy, and when it is close to the speed of light, the mass will become infinite, and it will require infinite energy, so light has no mass, it is essentially an electromagnetic wave, and light also has the properties of a particle, and because it is an electromagnetic wave, it has energy. >>>More
It should refer to an operation that brings a new number to a new number each time, until a certain step, the number starts to repeat, and so on.
White holes and black holes are both extremely mysterious celestial bodies in the universe, and the mechanisms by which they arise and operate are still not fully understood by humans. The conventional wisdom is that black holes devour everything and energy, while white holes, on the contrary, emit matter and energy forcefully. As a result, some people believe that white holes can eat black holes, but this is not a scientific fact. >>>More
