A singularity in space-time
TO achieve at least half a dozen major insights about the fundamental laws of nature in a single lifetime is rare, to say the least. Hawking proposed the existence of what are known today as “micro black holes”, conceptually similar to the giant objects formed by collapsed stars but completely different in scale. A year later James Bardeen, Brandon Carter and Hawking took this idea further and developed a set of “laws of black hole mechanics” that had an appealing parallel with the four established laws of thermodynamics. Hawking continued to reflect on this puzzle, and two years later, in 1975, he came out with his magnum opus, a paper titled “Particle Creation by Black Holes”. As Hawking dramatically observed in a follow-up paper, the energy released in the end stage of black hole decay would be “equivalent to about 1 million 1 Mton hydrogen bombs”.
