Black Hole

Black hole in astronomy is a theoretical region in space with such intense gravitational forces that nothing, not even light, can escape from it. Calculations based on Einstein’s general theory of relativity published in 1915 indicate that a very high concentration of matter can form …

Although we know a lot about black holes, there is still so much that we don’t know and that remains a mystery to us. What we do know is that it is a hole in space where gravity pulls so much that even light cannot …

Black Holes: Facts

Black holes are volumes of space where gravity is extreme to prevent the escape of even the fastest moving particles. The gravity is so strong because the matter has been compressed into tiny space. This can be formed by the death of massive star. They …

What Is a Black Hole

The start of a black hole’s life comes from the end of a very large star’s life. A black hole occurs after a supernova explosion. That star usually has a very big core. A star the size of our sun will end its life as …

Black holes are objects so dense that it is not possible for even light to escape their gravity. There are two main processes continuously going on in massive stars. 1. Nuclear fusion: This process takes place in the stars which tends to blow the star’s …

A black hole is a region of spacetime where gravity is so strong that nothing — no particles or even electromagnetic radiation such as light — can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

Density : about two quadrillion grams per cubic cm


Most stellar black holes, however, are very difficult to detect. Judging from the number of stars large enough to produce such black holes, however, scientists estimate that there are as many as ten million to a billion such black holes in the Milky Way alone.

Average mass

A typical stellar-class of black hole has a mass between about 3 and 10 solar masses. Supermassive black holes exist in the center of most galaxies, including our own Milky Way Galaxy. They are astonishingly heavy, with masses ranging from millions to billions of solar masses.


This phenomenon is thought to be the final fate of the massive stars (see black hole). The Schwarzschild radius (Rg) of an object of mass M is given by the following formula, in which G is the universal gravitational constant and c is the speed of light: Rg = 2GM/c2.


What is black hole in simple words?
A black hole refers to a spot in space where gravity pulls too strongly that even light cannot escape. Because of how much matter has been compressed into such a small area, gravity can be so strong. This can happen if a star is about to die. People can't see into black holes because there is no light.
What is black hole introduction?
A black hole can be defined as an object so dense, that no light can escape its surface. ... If the Earth's masses were compressed into an elongated sphere, with a radius of 9mm, the escape velocity is the speed at which light travels. The escape velocity is a tiny bit lower than the speed limit, but it's still quite impressive.
What can we learn from black holes?
In the centres galaxies, massive black holes release enormous amounts of energy. This is what plays an important role in how our galaxy evolves. Black holes can be impressive as well as amazing objects. They are also unique laboratories that permit the testing of strong gravity and extreme matter.
Why is called black hole?
A black hole absorbs any light that comes in its path. It reflects nothing, like a perfect-black body in thermodynamics. Quantum mechanics says that black holes can have a temperature and emit Hawking radio, which slows down their shrinkage.
