Black hole is the only thing in the Universe that can trap light by gravitational force. They are formed by the collapse of star with such a for ce that t warps lights abd time in itself. When a star burns through the last of its fuel, it may collapse, or fall into itself. For smaller stars, up to about three times the sun's mass, the new core will be a neutron star or a white dwarf. But when a larger star collapses,it compresses to create a stellar black hole. Scientists aren't certain how such large black holes spawn. Once they are formed, they gather mass from the dust and gas around them, allowing them to grow to enormous sizes.

Some think that black holes suck everything from the space that is around them when, in fact, black holes are like any other object in space, albeit with a very strong gravitational field. If you replaced the Sun with a black hole of equal mass, Earth would not get sucked in – it would continue orbiting the black hole as it orbits the Sun, today.

It might sound crazy that black holes could spawn new universes – especially since we're not sure other universes exist – but the theory behind this is an active field of research today. The deepest of wells in the space are made by black holes. blace is such a deep well in space such that not even a light cannot come out of the black hole. The inner region of a black hole, where its mass lies, is known as its singularity, the single point in space-time where the mass of the black hole is concentrated. Scientists say that the miniature black holes may have formed immediately after the Big Bang.

Rapidly expanding space may have squeezed some regions into tiny, dense black holes less massive than the sun. If a star passes from close distance to a black hole, it can be torn apart. Astronomers estimate there are around 10 million to a billion stellar black holes, with masses three times that of the sun, in the Milky Way.

The only difference between a black hole and our Sun is that the centre of a black hole is made of extremely dense material, which gives the black hole a strong gravitational field. It's that gravitational field that can trap everything, including light, which is why we can't see black holes. So this is some of the useful information about black hole. Black hole is surely a miracle and it is really interesting to know more about it.
