What is the theory for the formation of black holes?

The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of no escape is called the event horizon.

How many theories are there about black holes?

There are two theories on how binary black holes form. The first suggests that the two black holes in a binary form at about the same time, from two stars that were born together and died explosively at about the same time.

What evidence is there for supermassive black holes?

Direct evidence for a supermassive black hole – a plot of the orbital motion of the star S2 around the centre of the Milky Way. From these observations, astronomers have inferred that a supermassive black hole of about 3 million solar masses lurks at the centre of our galaxy.

What are 5 cool facts theories about black holes?

10 Fun Facts About Black Holes

• You Can’t Directly See a Black Hole.
• Our Milky Way Probably Has a Black Hole.
• Dying Stars Lead to Stellar Black Holes.
• There are Three Categories of Black Holes.
• Black Holes Are Funky.
• The First Black Hole Wasn’t Discovered Until X-Ray Astronomy was Used.

How are supermassive black holes formed?

One possible mechanism for the formation of supermassive black holes involves a chain reaction of collisions of stars in compact star clusters that results in the buildup of extremely massive stars, which then collapse to form intermediate-mass black holes.

How were supermassive black holes formed?

What should you know about the formation of a supermassive black hole?

For that, you should have to know about the formation of a supermassive black hole. Supermassive black holes are those Black Holes, whose masses are million to billion times more than the mass of the sun, contrary the stellar black holes have masses of few times of the sun.

Are black holes formed after the death of stars?

Generally, We readout that stellar black holes are formed after the death of stars, but some scientists think that when there was the first star of the Universe, then the black hole also existed at that time. It means, there is no link between the formation of the black hole and the birth or death of the star.

What happens to gas clouds when black holes form?

As more and more black holes—and stars and galaxies—were born and started radiating energy and light, the gas clouds evaporated. “The overall radiation field in the universe becomes too strong to allow such large amounts of gas to collapse directly,” Basu says.

Are black holes at the center of galaxies getting bigger?

Recently studies say that black holes at the center of galaxies are getting bigger and bigger, they are swallowing matter enormously. Sagittarius A* is equal to the 4 million solar masses, this supermassive black hole is located in the center of our Galaxy Milky Way. It has an estimated diameter of 44 million kilometers.
