BIG UNKNOWNS. “These theorems claim to assume nothing about the unknown behavior of quantum gravity in regions of very high curvature” inside a black hole. https://lnkd.in/dUKnus8 View in LinkedIn

THE INFORMATION PROBLEM. “BH to WH scenarios, provided they can be given a solid foundation in quantum gravity, give a simple resolution of the black hole information problem and are counter-examples to propositions that form the basis of much of the work on quantum properties of black holes, such as the generalized second law and theorems predicting singularities in the interior of quantum black holes.” BH = black hole; WH = white hole).

KEY ASSUMPTION. “In this paper I assume that almost all of the negative energy associated with Hawking "partners" remains inside the white hole until it interacts with the rebounding matter that formed the black hole.” https://lnkd.in/dUKnus8 View in LinkedIn

TRANSITION EXPLAINED. “I have demonstrated that a smooth quasi-classical transition from an evaporating black hole to a white hole is consistent with a spacetime with the global causal structure of Minkowski spacetime, and does not require any large quantum effects outside regions of Planckian spacetime curvature. Whether this is actually consistent with quantum gravity remains an open question.” https://lnkd.in/dUKnus8 View in LinkedIn

LIFELORE. “Biology derives from the Ancient Greek words of βίος romanized bíos meaning 'life' and -λογία; romanized -logía meaning 'branch of study' or 'to speak'. Those combined make the Greek word βιολογία romanized biología meaning 'biology'. Despite this, the term βιολογία as a whole didn't exist in Ancient Greek. The first to borrow it was the English and French (biologie). Historically there was another term for biology in English, lifelore; it is rarely used today.” https://en.m.wikipedia.org/wiki/Biology View in LinkedIn

GEOMETRIC SPECULATION. “If two particles moving in a straight line directed opposite to each other in the spacetime then they can collide at any point. Collision of the particles occurs close to the outer horizon of the white hole. The second particle emanates from the white hole region should lapse near the bifurcation point but not crosses this point, because if it crosses this point, it would come into the T−region instead of R−region.” https://link.springer.com/chapter/10.1007/978-3-030-51081-7_62 View in LinkedIn

THE FOOTNOTE ANSWER. “The presence of white holes is controversial. Especially, they can be unstable. Several years ago, an interesting speculation was explained which conclude that white holes can act as region retarded in the expansion of surrounded matter in Universe.” https://link.springer.com/chapter/10.1007/978-3-030-51081-7_62 View in LinkedIn

FOOTNOTE OF THE FOOTNOTE. “Since the spacetime of the eternal black hole includes unavoidably two regions; black hole and white hole…the first particle progresses towards the future horizon and second particle accesses the past horizon from the inner white hole region.” https://link.springer.com/chapter/10.1007/978-3-030-51081-7_62 View in LinkedIn

GENERAL CASE OF FOOTNOTES. “Afterward, this effect was generalized to three cases: non-extremal black holes, generic rotating black holes and nonrotating charged black holes. In all three cases, it is indicated that both particles move towards the horizon of the black holes.” https://link.springer.com/chapter/10.1007/978-3-030-51081-7_62 View in LinkedIn
