Supermassive black holes have masses between 1 million to 1 billion times more than ordinary stellar black holes.
Although little has been confirmed, they are likely at the center of some large galaxies. Including our galaxy, namely the Milky Way. Most are difficult to observe because they are too far away.

Supermassive Black Hole Facts
After years of observation, astronomers don’t have much evidence for supermassive black holes
But the most convincing thing is the existence of quasars in active galaxies far away. Observations of the timescale of quasar variability and energy output reveal a number of facts.
The hole emits a trillion times more than the Sun. If you look at it from an area the size of our Solar System.
You need to know, one of the mechanisms that can create energy on a large scale is the conversion of gravitational energy into light by a large black hole.
Launching the Space.com page, black holes in the universe formed very quickly, when the cosmos was less than a billion years old.

It formed very early, so it probably didn’t form from the death of a massive star as some theories have suggested.
To test it, a team of astrophysicists had the idea of observing the elements around this supermassive black hole.
The mass of stars is generally 10 to 24 times greater than the sun. The research team began to see it as another star approached.
The gravity of the hole will trap some of the material around it. Then in the process it produces x-rays.
Black holes are mostly difficult to detect. Because when viewed from the number of stars large enough to create such a hole.
According to scientists, the estimated number of black holes is in the billions like those in the Milky Way.
Giant Black Hole
A black hole is a large amount of matter packed into a small area. Like a star ten times the size of the sun, then squeezed into a ball the size of the moon.
As a result, it causes a strong gravitational field. Not even light would be able to escape. Astronomers cannot directly observe supermassive black holes using telescopes.

However, deduce the existence of these holes by studying them by detecting effects on nearby matter.
If a black hole could pass through accretion, then a similar process could occur if a normal star passed nearby.
In this case, the black hole would rip apart a normal star as it pulled toward itself.
Black holes have the potential to emit gamma-ray bursts, eat up nearby stars, and affect the growth of new stars in some areas.
As the name suggests, supermassive black holes are gigantic in size. For the smallest size millions of times larger than the sun.
In the modern universe as it is today finding a giant black hole is not surprising anymore. The reason is, the black hole has had billions of years of swallowing gas and dust.
But when astronomers found them earlier, they formed quickly. When the universe was less than a billion years old, the first galaxies and stars were just forming.
Of course the formation of giant black holes too early, already beyond the limits of the revealed astrophysical processes.
The End of One Star is the Beginning of a Black Hole
Most supermassive black holes are formed from the remains of large stars that die in supernova explosions. When a star collapses, its surface approaches the imaginary surface.
The time on the star will be slower than the stored time. If the surface reaches the horizon, the star will not collapse.
Even large black holes come from colliding stars. NASA’s Hubble Space Telescope collects data along with observations from astronomers.
The conclusion is that powerful explosions can occur when a neutron star collides with a black hole, creating another black hole.
Recently, there is direct evidence for the existence of supermassive black holes. The hole comes from observing matter orbiting the galactic center.
Compared to stars and gas, their orbital speed is higher. Then there is another acceleration in the presence of a massive object with a strong gravitational field around a small region of space.
Actually, astronomers are still not sure about the formation of supermassive black holes. The reason is, there is an opinion if the hole comes from a massive star, the collapse of a massive gas cloud, until the star swallows large amounts of material. (R10 / HR-Online / Editor-Ndu)
