    Frozen Star- Black Hole

    All of us would have heard about black holes at some point of time in our life. Let us look into what are black holes and the science behind them.
    A black hole was discovered by Louise Webster and Paul Murdin, who were British astronomers. Einstein was the first one to predict the existence of it. Thomas Bolton, a student found out that there existed a massive but invisible object.
    As its name suggests is not a hollow hole. It contains a bulk of matter that one couldn’t even imagine. The gravity of it is the pace is too strong for any particle to escape it. Even light, which is a form of electromagnetic radiation, cannot escape it.
    As per scientific research, they are invisible since no light can get out of it. They can be both big and small. Scientists believe that the small ones were formed when the universe first evolved. Steller is the kind of black hole that has its mass 20 times more than the sun’s mass.
    Einstein’s theory of general relativity showed that it leaves a dense remnant core when a star dies. The force of gravity exceeds all the forces and produces it, if the mass of the core is more than three times that of the mass of the sun. A star’s ending marks the beginning of a black hole.

    Some of the names of black holes are:

    v Arp 220
    v 1ES 2344+514
    v AP Lib
    v HE0450-2958
    v GRS 1915+105/V1487 Aql
    These are some of them recorded by scientists. A0620-00, or V616 Monocerotis, Cygnus X-1, V404 Cygni are some of the closest black holes to earth.
    This is how they are formed. These mysterious objects which make us question the miracles hidden in the universe are tremendous in their deed. There is so much more the humans are yet to discover.
