The mystery of Black Hole



“In space, no one can hear you scream;

and in a black hole,

no one can see you disappear.”

Stephen Hawking, “Black Holes: The Reith Lectures”


Origin of a black hole

A region of space-time from which not even light can escape. The fundamental force of nature's gravitation is the leading lad here and is so strong at the core of a black hole that it does not allow any electromagnetic radiation or light to escape. The concept of the black hole is dated as back as 1784. Albert Einstein predicted the existence of a Black Hole in 1916. And the term was coined in 1967 by American astronomer John Wheeler.

There are four types of black holes:


1. Stellar

2. Intermediate

3. Supermassive

4. Miniature


Formation of a black hole

Going straight to the origin of a black hole in the space, we find that stars are a collection of huge amount of hydrogen atoms which collapse under their own gravity to form a very dense core undergoing nuclear fusion to release helium and an enormous amount of energy in form of radiation.

This radiation pushes against gravity and maintains a delicate balance between gravity and radiation. But stars with higher masses than the sun experience a high amount of heat and pressure to fuse heavier elements. Something happens when the star starts fusing Iron. Suddenly the balance between outward radiation and inward gravity gets disturbed, and the core collapses. The star implodes at the rate of a quarter of the speed of light resulting in a Supernova Explosion and eventually, the star dies.

This very incident results in a Neutro Star or if the star is massive it results in a BLACK HOLE.



Is the black hole really black?

A black hole is made up of five main parts:

1. Accretion disk

2. Shadow

3. Photon ring

4. Event horizon

5. Singularity


With all the part of the black hole being less discovered the event horizon is said to be the point of no return and the escape velocity be the speed of light.

So when the black hole is so black that not even light could escape it. How could we find it to exist? So there is no way to search a black hole but only the boundary, discovering the event horizon is the way to discover the black hole which basically exists in the center of most of the galaxies.



The black hole information paradox

20th century most famous scientist Stephen Hawking in his exploration of cosmos and black holes gave one of the most significant discoveries called Hawking Radiation. This radiation is related to the black hole which is a connection between physics most controversial topics. The unified field theory which may wrap up the theory of relativity and quantum physics. The paradox states that black hole unlike the mentions of the same in the theory of relativity undergoes constant decaying of information through a series of reactions between the matter and antimatter particles at the event horizon resulting in escaping energy at a very slow rate. It is basically the evaporation of black holes so slow in time that even the universe ceases to exist before that.

All the information which gets dumped in the black hole is said to be gradually get erased in subsequent radiations. Ending up with many physical states devolved into a single state.

We don't know whether the information paradox is true or not. What we know for now is that science is not stagnant. But it has reached a position from where there is a very thin string hanging to discover the mysteries of the universe. Maybe everything goes back to basics.

Back to metaphysics, to philosophy to spirituality.
