Information transfer from black holes via white holes
K. Ropotenko
It is shown that a black hole can be in two states: one with positive and other with negative surface gravity . The state with corresponds to a white hole. In this state t…
Contradictory implications of the nonadditive entropy
K. Ropotenko
It is shown that the concept of nonadditive black hole entropy leads to the contradictory implications in the framework of statistical thermodynamics. In particular, a black hole w…
Microcanonical distribution for black hole with allowance for nonadditivity
K. Ropotenko
It is shown that with allowance for nonadditivity the (canonical) distribution for a black hole transforms to a (microcanonical) distribution which depends on nonadditive integrals…
The entropy and mean separation between energy levels of black hole
K. Ropotenko
According to the widely accepted statistical interpretation of black hole entropy the mean separation between energy levels of black hole should be exponentially small. But this sh…
Quantization of the black hole area as quantization of the angular momentum component
Kostyantyn Ropotenko
In transforming from Schwarzschild to Euclidean Rindler coordinates the Schwarzschild time transforms to a periodic angle. As is well-known, this allows one to introduce the Hawkin…
What is the maximum rate at which entropy of a string can increase?
K. Ropotenko
According to Susskind, a string falling toward a black hole spreads exponentially over the stretched horizon due to repulsive interactions of the string bits. In this paper such a…
