As that invisible black place pulls everything, it led to the formation of the name black hole. Powerful telescopes with specialized tools, stationed in both earth and space, can only detect these black holes. Despite exhibiting dangerous properties, black holes do not cause any major threat to earth and its people.
Black holes are formed when star undergoes destruction, although not all stars destroy themselves. “While most stars end up as white dwarfs or neutron stars, black holes are the last evolutionary stage in the lifetimes of enormous stars that had been at least 10 or 15 times as massive as our own sun” . The fact is that because of the massiveness of these stars and the resultant presence of vast gas in it, intense gravitational field normally builds up and tries to collapse the star. In a way, it can be said that increased fusion reactions that happens in the star’s core would be like a giant fusion bomb which can explode the star. Then when the star eventually dies, the above-mentioned nuclear fusion reactions stops as the fuel needed for these reactions burns up. However, at the same time, the intense gravitation of the star pulls the materials inwards and in the process compresses the core. Then, “as the core compresses, it heats up and eventually creates a supernova explosion in which the material and radiation blasts out into space” . After the blast, the remaining thing is the extremely compressed and exceedingly massive core, whose gravity is so intense that no material including light can escape from it. Then, as there is no force to control this intense gravity, an about-to-be formed black hole shrinks further to attain zero volume, after which the black hole becomes infinitely dense. As mentioned above, even the light that is generated from the collapsing star is unable to get out of it because of its intense gravitational pull. As the stars own light is trapped within its orbit, it makes the specific location invisible and
