Introduction to Black Hole Seminar Topic:

According to the theory of relativity a black region in the space from which nothing can be escaped including light. It is a just like black body which does not show any reaction with any light or say do not reflect anything on passing light. Around this black hole there is unpredictable area. When any gas falls into the black hole that gas goes in the black hole and then lots of radiation is transferred that can be detected on the earth. There is lots of black hole in the universe.

According to the hair theorem anything that achieves the stable condition after formation, black hole has three only three independent properties: mass, charge and angular momentum. They are usually classified according to the mass, charge or angular velocity.

Photon sphere: any spherical boundary that have zero thickness, such that photons it contain are moving along the sphere. Light are able to cross the photon sphere but they are captured by the black hole.

Ergo sphere:  it is the region outside the event horizon where the bodies are continuously moving. If any which is near the moving object then it will also start moving along the origin.

Gravitational collapse: when the object does not have enough power to hold down its own gravitational force then they collapse itself. This might create black hole.

Quasi-periodic oscillations: they are the material moving along the inner edge of the accretion disk. When the X-ray from accretion creates the flickering around the object at certain frequency then these signals are quasi- periodic signals.

If the collision takes place at higher rate than it also creates the microscopic black holes. Stephen hawking’s said that total area of the hole never decreases whether they merge. And total energy or entropy never decreases.
