In our space there are many mysterious place where nothing can come out.This place is full of amazing things which concern our people.People in general are necessarily come to contact with the word 'Black hole'.From the name we can find it's nature.Black hole is a region of space from where no light or nothing can come out.From relativity we know a sufficient mass of a star form a black hole at the end of the star at least 10 to 15 times as massive as the sun.There is a surface from where a black hole is detected is known as 'Event horizon'.
Quantum mechanics predicts that a black hole naturally emit radiation at a finite temperature.During 1960s theoretical work showed black hole were a generic prediction of general relativity.Karl Schwazschild was the man who first found the mathematical calculation of black hole by general relativity.after a black hole formed it can enlarge it's area by absorbing mass from its surroundings.Someone shows the idea of super holes exist in the center of most galaxies.Since stellar black holes are small and light that would allow us to see them.A black hole floating alone the space would be enough hard to realize.
