A BIT OF EVERYTHING. “The Hawking radiation is entangled with Hawking "partners." If these are trapped inside the black hole, and if the black hole evaporates completely without release of the quantum information associated with the Hawking "partners", an initial pure state would not evolve into a pure state as determined by observers who remain outside the black hole.” https://lnkd.in/dUKnus8 View in LinkedIn

“EMERGENCE refers to how collective properties arise from the properties of parts, how behavior at a larger scale arises from the detailed structure, behavior and relationships at a finer scale.” These Alhambra -inspired tiles illustrate this clearly: close up you cannot see the braid patten that emerges from a distant view at an angle. https://lnkd.in/ddN-5UY View in LinkedIn

YIKES! “I described a class of spherically symmetric models for an evaporating black hole evolving into a white hole, based on an explicit ansatz for the form of the metric, with a negative energy inflow of Hawking "partners" along ingoing radial null geodesics in the interior of the black hole.” https://lnkd.in/dUKnus8 View in LinkedIn

THE CONNECTOR. “The transition from the black hole to the white hole has often been described as a "quantum tunneling" process between two quite distinct classical geometries, perhaps even before much evaporation has taken place.” https://lnkd.in/dUKnus8 View in LinkedIn

IN PLAIN SIGHT. “If there was a pure quantum state before the black hole formed, the final result is also a pure state. It is remarkable that the possibility of such a simple resolution of the black hole information problem has been ignored by so many.” https://lnkd.in/dUKnus8 View in LinkedIn

INFORMATION PARADOX. “If this can be accomplished in a spacetime with the same causal structure as Minkowski spacetime, all quantum information trapped by the black hole eventually escapes from the white hole and reaches distant observers.” https://lnkd.in/dUKnus8 View in LinkedIn

ALTERNATIVE SOLUTIONS. “On the other hand, arguments have been made based on Loop Quantum Gravity (LQG) that singularities in the black hole interior can be resolved, such that the black hole transitions into a white hole.” https://lnkd.in/dUKnus8 View in LinkedIn

CLASSIC + QUANTUM BLACK HOLES. “This has led some to propose a drastic quantum modification of the spacetime to prevent formation of a black hole horizon (fuzzballs, gravastars, etc.), even though quantum corrections naively should scale as h/ M 2 (units G = c = 1 ), which is incredibly small in the vicinity of the horizon of a large black hole.” https://lnkd.in/dUKnus8 View in LinkedIn
