In March 1974, Stephen Hawking announced: the paper that made his name. It involves the revelation that black holes (gravitational giants from which not even light can escape) will not continue to grow until the end of time, but will slowly shrink as they emit particles in a phenomenon now called Hawking radiation. was included.
Its meaning was incomprehensible. Hawking's calculations showed that the radiation must be random and there is no way to predict what types of particles will appear. The problem is that anything that falls into a black hole contains information about what kind of particles it is made of, its composition, its quantum state, etc., and if what comes back is random, then its The information was that as soon as the object fell, it was lost forever. 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 and destroy everything they pull in? This prospect is called the black hole information paradox. This theory has fascinated physicists for decades because it not only highlights the deep disconnect between general relativity, Albert Einstein's theory of gravity, and quantum theory, but also offers hope for reconciliation. Ta.
Now, 50 years after its creation, this contradiction has largely been resolved. But physicists are not as happy as you might expect, as their solution does not yield the long-sought quantum theory of gravity. In many ways, the mystery of what's going on inside Black only deepens…
