A black hole is a region of spacetime where gravity is so strong that nothing — no particles or even electromagnetic radiation such as light — can escape from it.
Prof. Stephen Hawking shined a light towards the existence of Black holes. He accentuates that the way black holes operate puts the two fundamental theories at paradoxical to each other.
Scientists say that they have resolved the biggest paradoxes of all time. This theory by Stephen Hawking puzzled the scientists. The fear with prof. Hawking's paradox is that it undermines the two most important theories of the universe. The first is Einstein's “Theory of Relativity” and the other one is “quantum mechanics”.
According to Hawkings, the one these two fundamental theories might be flawed. This terrifies the physicists because on these two theories almost every understanding principle of the universe is postulated.
But now the paradox is resolved by something which is named “quantum hair”. Earlier Prof. John Archibald Wheeler of Princeton University in New Jersey in the 1960s proposed the “no-hair theorem”, this name of the theorem suggests the mathematical description of the black hole; something that doesn’t have any physical features.
The "yes hair theorem" claims to resolve the paradox by bridging the gap between general relativity and quantum mechanics. The notion of quantum hair allows information about what goes into a black hole to come out again without violating any of the important principles of either theory. It is a simple and elegant solution.
"In the past few years, it has been recognized that the no-hair theorem fails due to quantum effects and this resolves Hawking's paradox,"- states prof. Raju of International Centre for Theoretical Sciences
