What is a black hole?
A black hole is a place in space where gravity pulls so much that even light does not pass through it. Gravity is so solid that the problem is pushed into place slightly. This is what happens when a star kicks a bucket.
Since light does not emit, individuals cannot see the dark gaps. They are indistinguishable. Space telescopes with specialized equipment can help detect dark gaps. Extraordinary equipment can comprehend how stars near dark openings work differently to different stars.
What is the number of black holes?
There are four types of black holes: the best, the middle, the supermassive and the smaller than the normal. Blackhole formation is the most commonly perceived path through the spectacular death. When the stars get to the parts of the bargain, most will blow up, lose mass and then cool down to shape the white minivan. In one case, the largest of these red hot bodies, 10 to many times worse than our own sun, turned out to be super-thick neutron stars or spectacular mass dark openings.
In their final arrangements, the massive stars depart with an extravagant flair in horrific explosions called supernovae. Such an explosion would take the stellar material into space but leave the best center. When the star is alive, the atomic fusion has made a constant external push, which is reasonable for the internal draw of gravity from the star’s own mass. In the best remains of a supernova, in any case, the forces that contradict that gravity are no more, so the star center begins to fall on itself.
In the event that its mass finally collapsed into a small droplet, a black hole emerged. Dark openings give their tremendous gravitational potential if they push most of that mass — usually our own sun’s mass — into such a small point. These wonderful mass dark spaces can be incorporated into our own Milky Way system.
How black holes start:
Most of the black holes are formed from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars that are not large enough to fall into the light trap.) If the star’s total mass (three times the mass of the sun), theoretically can be proven to be a star without collapsing under the influence of gravity. However, with the collapse of the star, a strange thing happens. As the star’s surface nears the binary hazardous surface known as the “event horizon”, time on the star slows down relative to the time most observers are placed. When the surface reaches the event horizon, the time is stationary and the star no longer collapses – it is a frozen collapsing object.
Larger black holes can be caused by stellar collisions. Soon after its launch on December 2004, NASA’s Swift Telescope noticed a powerful, fleeting light known as explosions of gamma rays. Lunar and NASA’s Hubble Space Telescope later collected data from the event’s “After Glow”, and the observations together show that astronomers could create powerful black holes and neutron star ideals, creating another black hole.
If the black holes are “black”, how scientists know they exist?
The black hole is invisible because strong gravitational light pulls through the center of the black hole. But scientists can see how strong gravity affects the stars and gas around the black hole. Scientists can study whether the stars are flying around the black hole orbiting.
When the black hole and star are together, high energy light is produced. We cannot see this kind of light with human eyes. Scientists use satellites and telescopes in space to see high energy light.
Can a black hole destroy the earth?
Black holes do not rotate in space by eating stars, moons, and planets. Earth does not fall into a black hole because no black hole is close to the solar system.
Even though the mass of sunlight is a black hole, the Earth is not yet inward. The black hole has the same gravity as the Sun. The Earth and other planets now revolve around the Sun as it circles the Sun.
The sun will never become a black hole. The sun is not a big star to make a black hole.

History of the black hole:
The idea of a body in which light is inescapable was also briefly proposed in a letter published in November 1784 by astronomer and English clergyman John Mitchell. Mitchell’s simple calculations assume that such a body has equal density with the sun, and that such a body is formed when the diameter of a star exceeds 500 suns and that the speed of escape of the surface exceeds the normal speed of light. Mitchell correctly recognizes that such supermassive but radiating bodies can be detected by their gravitational effects on nearby bodies. At the time, scholars were enthusiastic about the idea that giant non-invisible stars could hide in plain sight, but the excitement subsided when the wave nature of light became apparent in the early nineteenth century.
If the light is a wave rather than a “corpuscle”, it is unclear what effect the gravity will have on the escape of light waves. Modern relativity denies Michelle’s conception of a light beam shooting directly from the surface of a supermassive star. The star’s gravity stops and then drops back to the star’s surface.
