A survey paper on the identification and behavioral aspects of Black Holes

Our universe is so vast that the observable universe is just 5% as per some study. In this observable universe there are billions and billions of stars, galaxies and other massive formations. Black holes are one among them. But it gains attention due to its extreme gravitational force that even light can’t escape from this and hence can’t be seen. However, its behavior can be experienced and thus can not only identify but also analyses them in detail. This paper gives some light on the research made on black holes by some of the eminent professionals and thus summarizes it so that, this forms a stepping stone for further research.
