A black hole is an area in space where the force of gravity is so strong that light cannot escape. Strong gravity occurs because the substance has been suppressed in a small space. This compression can occur at the end of a star’s life. Some black holes are the result of dying stars.
Because no light can escape, black holes are invisible. However, space telescopes with special equipment can help find black holes. They can observe the behavior of materials and stars that are very close to the black hole.

What is a Black Hole?
Black holes are points in space that are so dense that they form deep gravitational sinks. Beyond a certain area, even light cannot survive the powerful tug of gravity of a black hole. And whatever ventures too close be it stars, planets, or spacecraft will be amplified and compressed like putty in a theoretical process aptly known as spaghettification.
There are four types of black holes: Stellar, Intermediate, Supermassive, and Miniature. The most common way of becoming a black hole is stellar death. As the stars reach the end of their lives, most will flower, lose mass, and then cool to form white dwarfs.
But the largest of these fiery bodies, which are at least 10 to 20 times larger than our own Sun, become either super-dense neutron stars or so-called stellar-mass black holes. In its final stages, giant stars go with a blast in large explosions known as supernovae.
Such bursting stars move out into space but leave the stellar core behind. When the star was alive, nuclear fusion created a continuous outward push that balanced the incoming pull of gravity from the star’s own mass.
How Black Hole are Formed?
Blackhole, a cosmic body of extremely intense gravity from which nothing, even light, can escape. The death of a massive star can create a black hole. When such a star has exhausted the internal thermonuclear fuel to its core at the end of its life.
The core becomes unstable and collapses gravitationally on its own, and the outer layers of the star fly away. The crushing load of the constituent material falling from all sides compresses the dying star to a point of zero volume and infinite density called eccentricity.
How are Black Hole Detected?
Astronomers believe that supermassive black holes lie at the center of almost all large galaxies, even our own Milky Way. Astronomers can detect them by looking at nearby stars and their effects on the stars around them.

Can Humans Travel through the Black Hole?
The resulting desolate black hole would have such a powerful gravitational pull that even light could not escape it. So, do you find yourself on the event horizon – the point at which light and matter can only move inward, as proposed by German astronomer Karl Schwarzschild – there is no escape.
According to Massey, the tidal force will reduce your body to atoms and the object will eventually crush at eccentricity. The idea that you can get out somewhere – perhaps on the other side – seems completely hypothetical.
How Does Black Hole Works?
As the star dies, nuclear fusion reactions stop because the fuel for these reactions burns. At the same time, the star’s gravity pulls the material inward and compresses the core. As the core shrinks, it heats up and eventually explodes into a supernova in which material and radiation explode in space.
What is left is a highly compressed, and extremely large, core. The gravity of the core is so strong that even light cannot escape. This object is now a black hole and virtually disappears from view.

Because the gravity of the core is so strong, the core sinks through the fabric of space-time, creating a hole in space-time – which is why the object is called a black hole. The core becomes the central part of the black hole known as eccentricity. The opening of the hole is called the event horizon.
You can think of the event horizon as the mouth of a black hole. Once something passes through the event horizon, it is gone for good. Once inside the event horizon, all “events” stop, and nothing can escape.
The radius of the event horizon is called the Schwarzschild radius, named after the astronomer Karl Schwarzschild, whose work gave rise to the theory of black holes.
