What are Black Holes ?
Black holes have not been proved to exist in space. Such phenomena which scientists consider must exist in the cosmos could explain the spinning of the galaxy,s. black holes as they are known are thought to be once enormous stars with unimaginable gravitational fields that they litarelly collapse in on themselves which means that light could not escape it. hence the name black hole. Einstein's universal model of relativity in the 20th century also the work of an Indian scholar, Subrahmanyan Chandrasekhar worked out the mathematical facts of how huge a star would have to be to produce a black hole. A black hole is believed to start with a star. The sun, with a diameter of about 870,000 miles, is considered a normal sized star, and is mainly a huge thermonuclear "reactor" which has enough "fuel" to keep it burning for many thousands of years. what happens when a star's fuel burns out? There are many things that can occour, depending on the size of the star. A cold burned out finished star is one example.very large stars hundreds of times larger than our sun have nuclear explosions constantly happening. When this nuclear energy is spent, however, such huge powerful stars undergo dramatic changes. A star can develop into a "neutron star." A neutron star can have a radius of about ten miles and weigh as much as hundreds of millions of tons per square inch. That's because with a neutron star, for example, you may have a body with a ten-mile radius have a gravity equivalent to a star the size of the sun. even larger stars scientists believe continue to collapse under their immense gravitational pull to a point where they basicly implode in on themselves to such a density that even light is twisted inside out And that's where the terminolagy black hole comes from, this immense density is apparently called[ i have read] a place-time bend. Its radius is much smaller than that of a neutron star. And, therefore, a "black hole of time an space" comes into being. A black hole has such a dense gravitational force that nothing, not even light, can escape its grip.

how do scientists know that black holes may be out there? well stars have been observed orbiting unseen objects and it is theorised these invisible objects must have unimaginable force to make a star orbit them.
