Black Holes- The Tiffin Girls’ School by Mowon Yoon

One interesting aspect of black holes is the issue of information. In classical physics, information cannot be destroyed or created but only transferred from one place to another. However, since not even light can escape a black hole, it seems that any information that falls into it is lost forever. In the 1970s, Stephen Hawking discovered that black holes emit a faint radiation, now known as Hawking radiation, near the event horizon. This radiation is explained by the creation of particle-antiparticle pairs from the vacuum of space, where one particle falls into the black hole and the other is emitted as radiation. However, a paradox arises if the information is carried by the particle that falls into the black hole, rather than being emitted as Hawking radiation, as the information would be lost. This issue remains an area of intense research.

Another interesting scenario related to black holes is the double-slit experiment. When an electron is sent through a pair of slits and is not observed, it creates an interference pattern that suggests the electron passed through both slits simultaneously, as if it were a wave. However, if an observer is present, the particle is recorded as having gone through only one slit, and the wave function collapses into a single, definite location. If the experiment were carried out near the event horizon of a black hole and observed from inside the black hole, the quantum state of the particle would collapse. This would imply that something done within the black hole could affect something outside it, which is not supposed to be possible according to our current understanding of physics.
