Previous Link Black Holes - Part 1: History, Indirect Detection and Types
Formation of Black Holes: Well Stars feed on fusion of Hydrogen Nucleus which collide to form Helium Nucleus, when the Food is insufficient, Helium Nucleus start colliding in other heavy nucleus and this chain continues till Iron Nucleus which can not collide to form further big nucleus. So.... Well then Gravitational Pressure and Energy Pressure fights resulting in Very Big Supernova Blasts turning the Star into Neutron Star and if still the balance of pressure is not stable, they will eventually collapse into Black Holes. Black holes are formed by collapse of stars having more than 3-4 times mass of Sun.
Composition of Black Holes:

Composition of Black Holes:
- Event Horizon: It is the black hole’s defining feature. This is the boundary where matter and electromagnetic radiation can only pass into the mass of the black hole and can no longer escape.
- Singularity: It is the eye (or center) of the black hole. This is a region when the curvature becomes infinite.
- Photon Sphere: It is a spherical boundary (with no thickness) where photons move perpendicularly to the sphere is trapped in an elliptical orbit with respect to the black hole.
- Ergosphere: It is the area where objects are always on the move as a result of a phenomenon called frame-dragging.
- Innermost Stable Circular Orbit or ISCO: Here particles stably orbit at various distances from a center object.
