In March 1974, it was published by Stephen Hawking the paper that gave him his name. He received revelation black holes – Gravitational giants, from which nothing, not even light, can escape – do not grow and grow until the end of time, but slowly shrink as they release particles in a phenomenon now known as Hawking radiation.
The consequences were mystifying. Hawking’s calculations showed that the radiation must be random, and offered no way to predict what kind of particles would be produced. The problem was that anything that falls into a black hole contains information (what kind of particles it is made of, their configurations, their quantum states) and if what comes out is random, that information is lost forever as soon as the object is there. sucked But physics works on the idea that if we know all the information about a system, we can reconstruct its past and predict its future.
Can black holes really do the impossible, destroying anything and everything they attract? This perspective is called the black hole information paradox. It has occupied physicists for decades, not only because it highlights the deep disconnect between general relativityAlbert Einstein’s theory of gravity, and quantum theory – but also because it offers the hope of reconciliation.
Now, 50 years after its creation, the paradox has been resolved. And yet physicists are not celebrating as expected, because their solution has not been sought for a long time quantum theory of gravity. In many ways, it has only deepened the mystery of what goes on inside the black…
