Today we are going to talk about the BLACK HOLE. As you may be knowing that the Black Hole is the last stage of the giant stars ie after the STARS die they form Black Holes. Black Hole is having high mass density at it's center and it absorbs everything that goes near it. Once if you are inside the black hole then it is impossible to come out of it. Even the light will absorbed by the Black Holes.
Black holes are the places where GRAVITY is so strong that it sucks everything in, including light as I have already told you earlier. It is said that if you fall into a Black Hole, then you would stretch like SPAGHETTI. Black Holes are formed when a star or galaxy get so dense that it collapses under the pull of its own gravity.
Black holes may even exists at the heart of the GALAXY. Gravity shrinks a Black Hole to an unimaginably small point called a SINGULARITY. Around a Singularity, gravity is so intense that space time is bent into a funnel. Matter spiraling into a black hole is torn apart and glows so brightly that it creates the brightest objects in the Universe - QUASARS.
The swirling gases around a Black Hole turn it into an electrical generator, making it spout jets of electricity billions of kilometers out into space. The opposite of Black Hole may be WHITE HOLES which spray out matter and light like fountains.
