what are blackholes?

Question

could anyone please tell me what a blackhole is?

Answer 1

Blackholes are regions in the space where the gravitational force of attraction is too high that even electromagnetic waves like Light cannot ecape.
It's formed when a sufficiently smaller mass is compressed into a small space or volume.This happens mostly after the Supernova explosion of a star.
The phenomenon that occurs is that the Nuclear Fusion Reaction inside a star,which exerts an Inward Pressue on the surface of the Star stops,the star collapses under its own Gravity as its Gravity becomes more than the Inward Pressure.The star ultimately reduces to the size of a point source known as Singularity whose Gravitational force is too high.It pulls everything in its surrounding in a Spiral Motion .The Escape Velocity is more than the Speed of Light i.e. INFINITY.
The region surrounding the singularity is known as the Ergosphere which is 10 miles from the Singularity.
The question that where the Matter goes after falling into a Blackhole is under controversy according to the General Theory of Relativity and Quantum Theory.

Answer 2

A black hole is a super dense object that has an intense gravitational pull. A black hole is a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull.

There are two parts to a black hole, a singularity and a event horizon.

The event horizon is where the force of gravity becomes so strong that even light is pulled into the black hole. Although the event horizon is part of a black hole, it is not a tangible object. If you were to fall into a black hole, it would be impossible for you to know when you hit the event horizon.

The singularity is not really a tangible object either. According to the General Theory of Relativity the Singularity is a point of infinite space time curvature. This means that the force of gravity has become infinitely strong at the center of a black hole. Everything that falls into a black hole by passing the event horizon, including light, will eventually reach the singularity of a black hole. Before something reaches the singularity it is torn apart by intense gravitational forces. Even the atoms themselves are torn apart by the gravitational forces.

Answer 3

black holes don't exist, they are infact pockets of vacuum in space created by collapsed stars ie gas. A center of the milky way has these small pockets due to the close proximity of the stars. As a matter of fact, black holes don't exist in our universe. The closest thing is really fast light from far away aka quasars. Each zodiac sign has these past universal functions of light which travel faster than the speed of light, are the brightest known objects and are in the outerboundaries of our universe. However, they are remnance of radiation connected to a great monad. By the time your refracted light were to reach these objects or vice versa, the universe would end and trillions of years would pass.

Answer 4

A black hole is caused by the collapsing of a star . The gravity is huge and as the material falls it also accelerates and as it approaches the speed of light the mass will increase to infinity. This is how a black hole is formed . The so called week force of gravity creates them.

Answer 5

A black-hole is a extremely dense object that sucks in matter & light within it's way.

Some say that there's another dimension on the other side of the hole, others say you simply die and you don't see anything.
