community", the dominant belief is that to resolve the information paradox, it is important to understand how the black-hole singularity is resolved. These scenarios are broadly called remnant scenarios since information does not emerge gradually but remains in the black-hole interior only to emerge at the end of black-hole evaporation. Other possibilities are also studied by researchers, which include a modification of the laws of quantum mechanics to allow for non-unitary time evolution. Some of these solutions are described at greater length below. Small-corrections resolution to the paradox This idea suggests that Hawking's computation fails to keep track of small corrections that are eventually sufficient to preserve information about the initial state. This can be thought of as being analogous to what happens during the mundane process of "burning": the radiation produced appears to be thermal but its fine-grained features encode the precise details of the object that was burnt. This idea is consistent with reversibility, as required by quantum mechanics. It is the dominant idea in, what might broadly be termed, the string-theory approach to quantum gravity. More precisely, this line of resolution suggests that Hawking's computation is corrected so that the two point correlator computed by Hawking and described above becomes and higher-point correlators are similarly corrected The equations above utilize a concise notation and the correction factors may depend on the temperature, the frequencies of the operators that enter the correlation function and other details of the black hole. Such corrections were initially explored by Maldacena in a simple version of the paradox. They were then analyzed by Papadodimas and Raju who showed that corrections to low-point correlators (such as above ) that were exponentially suppressed in the black-hole entropy were sufficient to preserve unitarity and significant corrections were required only for very high point correlators. The mechanism that allowed the right small corrections to form was initially postulated in terms of a loss of exact locality in quantum gravity so that the black-hole interior and the radiation were described by the same degrees of freedom. Recent developments suggest that such a mechanism can be realized precisely within semiclassical gravity and allows information to escape. See § Recent developments. Fuzzball resolution to the paradox Some researchers, most notably Samir Mathur, have argued that the small corrections required to preserve information cannot be obtained while preserving the semiclassical form of the black-hole interior and instead require a modification
