Formation of black holes essay

Rotating black hole — black hole that possesses spin angular momentum. Charged black hole — black hole that possesses electric charge. Virtual black hole — black hole that exists temporarily as a result of a quantum fluctuation of spacetime. Types of black holes, by size[ edit ] Micro black hole — predicted as tiny black holes, also called quantum mechanical black holes or mini black holes, for which quantum mechanical effects play an important role.

Formation of black holes essay

If the core remnant of a supernova exceeds about two solar masses, it continues to contract. The gravitational field of the collapsing star is predicted to be so powerful that neither matter nor light can escape it. Inside the event horizon the escape velocity i.

The radius of the event horizon is called the Schwarzschild radiusafter the German astronomer Karl Schwarzschildwho in predicted the existence of collapsed stellar bodies that emit no radiation. The size of the Schwarzschild radius is proportional to the mass of the collapsing star.

For a black hole with a mass 10 times as great as that of the Sunthe radius would be 30 km Stars with a smaller amount of mass evolve into less compressed bodies, either white dwarfs or neutron stars.

For example, if a black hole is a member of a binary star system, matter flowing into it from its companion becomes intensely heated and then radiates X-rays copiously before entering the event horizon of the black hole and disappearing forever. One of the component stars of the binary X-ray system Cygnus X-1 is a black hole.

What We Study

Discovered in in the constellation Cygnus, this binary consists of a blue supergiant and an invisible companion 8. Various astronomers have speculated that large volumes of interstellar gas collect and collapse into supermassive black holes at the centres of quasars and galaxies.

A mass of gas falling rapidly into a black hole is estimated to give off more than times as much energy as is released by the identical amount of mass through nuclear fusion. Accordingly, the collapse of millions or billions of solar masses of interstellar gas under gravitational force into a large black hole would account for the enormous energy output of quasars and certain galactic systems.

Supermassive black holes have been seen in other galaxies as well. In the Hubble Space Telescope provided conclusive evidence for the existence of a supermassive black hole at the centre of the M87 galaxy.

Ferrarese Johns Hopkins University and the National Aeronautics and Space Administration The existence of another kind of nonstellar black hole has been proposed by the British astrophysicist Stephen Hawking. These so-called mini black holeslike the more massive variety, lose mass over time through Hawking radiation and disappear.

If certain theories of the universe that require extra dimensions are correct, the Large Hadron Collider could produce significant numbers of mini black holes.
