From the obscure birth at the beginning of the twentieth century to their rise in importance at the end of the past century, black holes have constantly made us question the very foundations of what we thought we understood about physics. In the past three years, their properties have come to bamboozle us once more, making us question what we thought we understood.
The essential problem is how to talk about gravity and quantum mechanics consistently when discussing black holes. One might ask why this is important . The foremost and fundamental reason is simple. Quantum mechanics underlies all of reality, and we understand the framework that describes quantum origin of all the forces except gravity. Thus, if you claim to understand the quantum origin of gravity, then the first and important test is to describe black holes.This would then bring us one step closer to finding the one framework that describes all the forces. This story centres around the work of Stephen Hawking; more specifically, his work that applied quantum mechanics to black holes. He made the bold prediction that black holes violated the laws of quantum mechanics. Everyone saw no mistakes in his logic, but no one believed the conclusion. About twenty years later, a solution was proposed to this conundrum, but physicists in the last three years have realized that this proposed solution does not make sense.
