what is the black hole realy ?

Answer 1

a black hole is a star (2 or 3 times bigger than our sun) that when it runs out of fuel, the gravitational field take over and compresses it indefinitely until it reaches a critical radius called the Schwarzschild radius. and then becomes a black hole.

a black hole is simply a massive star that "died." simple!

Answer 2

a black hole is a real tear in space time over allmost all dimetions in our universe space time unversal rotation such as a black hole twisted backword would be space time but allot of enery in one place now hyperspace is the universal tim of the universe twisted to the right or rotation of the galaxcy a white hole emits energy from another universe and a black hole take energy out it is a balance that keeps each universe alive there are only two universe's the amount of enery to make a black hole in our universe you would have to use a huge sphere of space time in real life science and then twist time and space so teleportation is not possbille bu this is molecule lasers and teleportation confilct of what possible www.beyond-science.com or www.beyond-science.net

Answer 3

A black hole is an object predicted by general relativity[1] with a gravitational field so powerful that even electromagnetic radiation cannot escape its pu

Answer 4

black hole is once up on a time a star!!
as the star ages it undergoes changes like into various stages!!
at a stage 'chandrasekhar's limit' is applied and accordingly depending on the mass of that star the next stage of the star depends.......
now the BLACKHOLE IS a stage in which the star shrinks bue to own gravitational force....this force is so POWERFUL that even light can't escape from it... anything which comes near it pulled towards it!!!! even planets!! one cannot 'see' a black hole !!
if u find a group of stars moving together then u cab b sure thers a blackhole somewher around them.....such is its gravitational pull of attraction!!!!!!!

u can also find it by using various techniques like x-rays,,etc...,

hope u r clear..... look for the different stages of star... in www.wikipedia.com its really xcitin..........
