Black Hole: Was Einstein wrong? Relativity theory need a relook

September 25, 2020

A Black Hole discovery led scientists to call for a new theory to explain what happens at the centre of these cosmic anomalies, with one scientist pointing to the possibility that "Einstein's theory of general relativity is not correct."
The general theory of relativity was published by the physics genius more than a century ago, to refine Isaac Newton�s law of universal gravitation. Providing a unified description of gravity as a geometric property of space and time, or spacetime, this model is still currently used by scientists as an explanation of gravitation in modern physics. Einstein�s theory has important astrophysical implications as it alludes to the existence of black holes � cosmic phenomenon in which space and time are distorted in such a way that nothing, not even light, can escape.
At the centre of a black hole, as described by general relativity, may lie a gravitational singularity, a region where the spacetime curvature becomes infinite.
But while mathematics says a singularity is possible, nature apparently proves these do not exist, Discovery Channel�s �How The Universe Works� exposed.
The series explained: �When a giant dying star collapses, the mass of the star falls in and keeps falling in crushing down into an infinitely small point.
But physicist Max Tegmark believes the �singularity� is �just a fancy way of saying �we have no idea what is happening here�.�
Astronomer Phil Plait explained why some experts have an issue with using this theory.
He said: �The way our physics describes black holes when they form is you�re taking a finite amount of mass and you�re collapsing it down.
�Its volume should shrink all the way down to zero, but that means it has infinite density and infinite gravity.
�That doesn�t make sense.�
Theoretical physics Lawrence Krauss then explained why some are questioning Einstein�s theory.
He added: �If you make a prediction and the answer is infinite, then it tells you that there is something wrong with your prediction.
�We have never seen infinity in the universe.
�Maybe a black hole with an event horizon described by general relativity just isn�t the proper description of the physics.�
Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles.
