How big are black holes, and how big are black holes?

The largest black hole in the universe, Ton618, a quasar with a mass 66 billion times that of the Sun, a diameter of 384 billion kilometers, and a distance of 10.4 billion light-years from us, was first discovered by humans in 1970. ton 618 is a very distant and very bright quasar, which is a giant accretion disk of a supermassive black hole at the center of a huge galaxy.

How massive is a black hole?

This is undefinable.

Beyond the universe may be a powerful gravitational field, and even if humans get there, they are twisted into twists.

Infinity. A black hole is a celestial object that exists in the universe in modern general relativity.

The gravitational pull of a black hole is extremely strong, allowing the escape velocity within the event horizon to be greater than the speed of light. Thus, "a black hole is a celestial body with such a curvature of space-time that no light can escape from its event horizon".

In 1916, the German astronomer Karl Schwarzschild calculated a vacuum solution of Einstein's field equations, 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 - the "event horizon", once it enters this interface, even light cannot escape. This value is called the Schwarzschild radius, and this "incredible celestial body" was named a "black hole" by the American physicist John Archibald Wheeler.

Black holes cannot be directly observed, but their existence and mass can be known indirectly, and their effects on other things can be observed. Information about the existence of a black hole can be obtained by emitting "edge messages" of X-rays and rays from friction caused by the acceleration caused by the gravitational pull of the black hole before the object is sucked in. The existence of a black hole can also be inferred by indirectly observing the orbit of a star or interstellar cloud air mass, and its position and mass can also be obtained.

The size of a black hole is not fixed, and a black hole can be large or small. The smallest black hole observed so far is a black hole called XTEJ1650-500, which is only 24 kilometers in diameter and has a mass twice that of the Sun. Black holes are found in binary star systems.

We can only study black holes and judge the size of black holes by looking at the light and radiant energy emitted by gas clouds within their event horizon.

However, humans don't know how small the smallest black hole in the universe is. However, scientists estimate that there is also a very small black hole in the universe, but with a very large mass, much smaller than you might think. Although humans have made some progress in studying black holes, we still know very little about black holes because we cannot directly observe the interior of black holes.

A way to find a black hole.

The method is to use Hawking radiation. NASA used the Fermi Gamma ray telescope to try to find the existence of a primordial black hole, but unfortunately, it has not been discovered until today. Another approach is to observe changes in the surface of the star.

Because if a small black hole passes through a star, its density will allow us to observe vibrations, and some planets will even be affected. If this small black hole exists, it is a primitive black hole because today's black holes cannot form black holes with very small masses.

Black holes vary in size from about 994 trillion solar masses.

Black holes are the modern theory of general relativity.

, a celestial body that exists in cosmic space. The gravitational pull of a black hole is extremely strong, allowing escape velocities within the event horizon.

Greater than the speed of light. Thus, "a black hole is a celestial body with such a curvature of space-time that no light can escape from its event horizon".

How massive is a black hole?

Summary. Some scientists once believed that the upper limit of the mass of black holes was 400 to 60 billion times the mass of the sun, but astronomical observations have found giant black holes that exceed the mass of the sun by 60 billion times, such as ton 618, which is a quasar with a mass of 66 billion times that of the sun, which itself is equivalent to the mass of a galaxy, which is so large that it is jaw-dropping.

Everything in the world has its limit, and black holes should be like this, but the strange thing is that scientists have not found the mass or even the size limit of the volume of black holes, according to the existing theories, when some elementary particles with stationary mass collide at a speed close to the speed of light, it is likely to produce a black hole as large as elementary particles, but its existence time is extremely short, but the black holes that have been observed in the universe are larger than the mass of the sun, Even black holes hundreds of millions of times larger than the Sun abound, and they can exist for more than a trillion years, such as black holes and quasars at the center of some galaxies.

Hello, The newly discovered black hole is 70 times the mass of the Sun, and the mass of a Sun is kilograms, while the mass of the Sun is 330,000 times that of the Earth. Solar mass is a unit of mass used to measure stars or large celestial bodies such as galaxies. Its size is equal to the total mass of the Sun, which is about kilograms (usually taken kilograms).

The mass of the Sun is 330,000 times that of the Earth. It is widely accepted that the Earth's mass is calculated over a four-year period and costing hundreds of thousands of dollars, said Dr. Merkowitz and Professor Gondrak, physicists at the University of Washington, and the results of this calculation will be announced by the American Physical Society on April 30. The two physicists say they have come up with the most accurate calculations yet of the gravitational constants that affect each planet.

Although the speed of light and sound has long been known, the scientific community has not been able to solve the gravitational constant. Knowing the gravitational constant allows you to calculate the mass of the planet.

Possible. Maybe.

Almost. The size of the ability to accommodate the entire solar system.

A black hole is a hole with no mass.

It is also a product of the cosmic atmospheric swirl.

You can see through the whirlpool the dark background of the universe.

It's a planet in space.

A generator that collides with destruction while passing through a black hole.

Thereby. As a result, new planets are constantly being born in the universe.

and then destroy the cycle of the old planet.

Therefore. The universe is home to many, many black holes of various sizes.

It's hard to describe exactly how big a black hole really is.

If the earth becomes a black hole, it is the size of a village, and any matter can become a black hole, and the largest known black hole is the size of 10 million suns.

Wireless extension, incalculable!

The black hole has an excellent appetite, devouring almost everything that falls into its own boundary {scientifically called the limit}, and is a guy who doesn't even let go of light, so theoretically speaking, there is no upper limit to the mass of the black hole, and in reality, when the black hole is unable to eat more distant celestial bodies after devouring all the matter at its own boundary, its weight gain stops.

The largest black hole ever discovered is 18 billion times the mass of the Sun, and this black hole is about 3.5 billion light-years away from Earth.

When given the mass of a slightly smaller galaxy, it is interesting to note that around this huge black hole, there is a smaller mass black hole orbiting.

This little black hole is actually very large, with a mass 100 million times that of the Sun.

Small black holes make a big black hole for one week every 12 years, and in each cycle, the small black hole brightens sharply twice. Scientists through theoretical calculations and observations.

Indeed, this periodic brightening is due to the fact that the small black hole approaches the large black hole at a specific location in orbit at a speed of more than 100,000 kilometers per second and will be large.

The gas around the black hole rubs violently, resulting in the phenomenon of luminescence.

Theoretically, the mass of a black hole is a lower limit of swimming, at least times to a time of the mass of the Sun. Smaller than this celestial body due to the induction.

If the force is not enough, at most it can only form neutron stars, not black holes. How big is the smallest black hole ever observed? Recently American scientist view.

A small black hole with a mass of the Sun was detected, and he formed a binary star system with an ordinary star. When a small black hole accretes a large amount of gas.

X-rays are emitted periodically around the body, and it is through X-rays that scientists understand the mass of this black hole.

In the process of turning huge stars into black holes, the atomic structure of ordinary matter will be destroyed, and physicists do not know exactly what has changed.

Journey. Finding a black hole that is approaching the lower limit of the black hole mass theory allows physicists to better study how black holes form.
