what is a blackhole?

Answer 1

When your fat girlfriend bends over and moons you.

Answer 2

see before understanding the blackhole let us understand what is red gaint so that it will be easy for u to undrstand what is black hole:


when a star has burned its own fuel(hydrogen),the radiation force which is acting on exactly oposite side of the gravitational force


now when it happens the mass of that star collapse towards the centre of that star now if the star has the mass is more than 1.6 that of the sun then what happens due to that collapse of the mass gravity becomes the main force and that star comtinous to collapse further because of it s own mass and it never ends....

ths way a blackhole is fomed and as the big mas is locatd a a very small point the gravity of such point becomes too much so that the escape velocity becomes more than the speed of light...

Answer 3

A black hole is an object predicted by general relativity[1] with a gravitational field so strong that nothing can escape it — not even light.

A black hole is defined to be a region of space-time where escape to the outside universe is impossible. The boundary of this region is a surface called the event horizon. This surface is not a physically tangible one, but merely a figurative concept of an imaginary boundary. Nothing can move from inside the event horizon to the outside, even briefly.

Theoretically, a black hole can be any size. Astrophysicists expect to find black holes with masses ranging between roughly the mass of the Sun ("stellar-mass" black holes) to many millions of times the mass of the Sun (supermassive black holes).

The existence of black holes in the universe is well supported by astronomical observation, particularly from studying X-ray emission from X-ray binaries and active galactic nuclei. It has also been hypothesized that black holes radiate energy due to quantum mechanical effects known as Hawking radiation.

Answer 4

A very dense mass. So dense that you can get close enough to the center of it without going below its surface so that escape velocity is greater than the speed of light.

Answer 5

A black hole is a theoretical entity whose surface gravity is so intense a satellite would have to travel at the speed of light to remain in orbit!

Answer 6

A black hole is created when a star collapses into itself. It creates an area so dense even light gets sucked in.

Answer 7

it is a star that has explode. to give you an ex. look at your toilet as the star drop something in it will devastate the balk hole
