What is black hole?

What is black hole?: A black hole is a place in space where the gravitational force is high even light can not get out of it. The gravity is so strong due to the fact the matter has been squeezed into a tiny space. This can take place when a star is dying.

Because no light can get out, humans can’t see black holes. They are invisible. Space telescopes with special tools can help locate black holes. With the help of these special tools can see how stars that are very close to black holes act differently than other stars.

Who discovered the first black hole and when?

what is black hole

The existence of black holes was first predicted by Albert Einstein, with his general theory of relativity in 1916. The term “black hole” has to turn out to be coined a few years later in 1967 through American astronomer John Wheeler. After a long time of black holes being known as most effective as theoretical objects, the first bodily black hole ever observed became noticed in 1971.

How Do this black holes form?

Black holes are formed when star collapses into itself.And black holes are get huge massive depending upon the star mass.

How large the size of a black hole?

The size of black hole is not stable and black hole get bigger size as they consume the matter near to this.

What is inside a black hole?

A black hole is a huge amount of matter filled into a totally small — in fact, zero — the quantity of space. The result is a powerful gravitational pull, from which now not even light can escape — and, therefore, we have no information or perception as to what existence is like inside.

As items and material are drawn into a black hole, they’ll undergo a procedure evocatively called spaghettification. This is due to the fact gravity is so extreme and increasing so hastily as you approach the black hole that your head and feet could revel in extensively specific gravitational environments. You might be physically stretched out, and your sense of time would slow to a crawl inside the quick moments before you fell into the singularity, the zero-point of the black hole itself.

Which is the nearest black hole to Earth?

The nearest black hole from the planet Earth was discovered by the Astronomers from the European Southern Observatory (ESO), who mentioned the Universe today. It is located in the constellation of Telescopium (near the constellation of Sagittarius) just one thousand light-years away from the Earth, added the report. It is estimated that the black hole is at least 4.2 times the sun’s mass. The study revealing the details of the nearest black hole to the Earth has been published in Astronomy & Astrophysics. The astronomers are of the belief that a second mass like the one discovered now is on the horizon.
