Can anyone tell me about Black Hole?

Answer 1

It was a dungeon where British prisoners of war were held by troops of the Nawab of Bengal after the capture of Fort William on June 20, 1756. The POW's were held overnight in conditions so cramped that many died from suffocation, heat exhaustion and crushing.

Answer 2

A star at least 40 times the mass of the Sun, spinning so fast about several hundred miles a second at the equator, it barely keeps from flying apart. Near the end of its life, unable to resist the pull of its own gravity, the core of the star collapses to make a new black hole. But because the star has so much spin, some of the infalling material resist the tug of the newborn black hole. A swirling disk of material forms around the hole - a maeltrom deep within the doomed star. Without the spin, there would be no burst. friction heats the disk, whipping around the disk a thousand times a second, to 40billion degrees while new material keeps cascading in. Moments after the black hole forms, jets of superheated gas blowtorch outwards.

each jet may draw its energy directly from the friction in the disk, or from the newborn black hole, via the magnetic fields that link it to its surroundings. Like the original star, the black hole spins frenetically, causing the fields to stretch, twist,and snap like rubber bands, dumping vast amounts of energy into the disks.

Either way the jet shoot outwards, reaching the surface of the star in a mere 10 seconds. If the star retained its original envelope of hydrogen gas, the jet stops dead and the gammay-ray burst may fizzle. but if the powerful winds blow from some massive stars have strpipped away the hydrogen earlier in the stars life, the jet escapes, arrowing into space at more that 99% of the speed of light.

The black hole usually distort light and rays, in short.

Answer 3

a black hole is a dead star which compressed into a very small body whose gravity is very strong that it can suck all the things it comes close to and never let them out again. once the black hole is present, we can see some clear changes that are present. for example, experts have theorized that the sun would change shape and we would feel a difference in the earth's pull in gravity. this is a sign that a black hole is devouring our solar system. but, in our galaxy, there is one black hole considerably close enough to earth and in the distant future is possible to make contact with us.

so this ends my explanation about black holes. hope you find it useful.

and oh yeah, there is also this thing called a wormhole. maybe you should ask some thing about that too. it is really interesting.

Answer 4

A black hole is an object with mass so immense that space-time there is curved back on itself. Since everything in the universe is embedded in space-time, including light, nothing can move away from a black hole.

Answer 5

hello ,
sure I can tell you about black hole , it is burn from the star.
when the star becomes older she explodes making a black hole . it is forming from hydrogen(h2) and h3.it means that it is dead star , but the star should be big .the discovered scientist are thinking that the human can cross this black hole and he will be in another time and place .there are Small white holes comes out from the black hole , so the scientist are saying that we can sent a person to this black hole and he cans return on a white hole .

Answer 6

Aside from all the astro-physics, the black hole is but nature's own recycling center... And astronomers, physicists, cosmologists are slow to put that succinctly, but this is no more and no less than what a black hole is.

As above, so below...

Answer 7

A black hole would be a celestial body whose surface gravity was so strong that the surface escape velocity would be the speed of light.
This would prevent any light escaping from the surface which would render IT invisible
