INFORMATION PARADOX. “Quantum information falling across the event horizon is swallowed up by a singularity or disappears into a "baby universe", unless it can propagate acausally. Could it somehow all remain on or outside the event horizon even as the quantum fields propagate into the black hole?” https://lnkd.in/dUKnus8 View in LinkedIn

BUT OF COURSE. “The metric is smoothly continued into the white hole as a function of a coordinate z related to the circumferential radius by r2 = a2 + z2 , and the effective stress-energy tensor has an outflow of negative energy across the white hole horizon to future null infinity.” https://lnkd.in/dUKnus8 View in LinkedIn

TRANSITORY FORM. “Outside the black hole horizon there is a smooth transition to outflow of positive energy Hawking radiation. The transition to the white hole is at a minimum circumferential radius r = a.” https://lnkd.in/dUKnus8 View in LinkedIn

EVOLUTION TRENDS. “Generally, biological evolutions are increases of complexity and bio-information. They should correspond to entropy decrease.” https://lnkd.in/d_VMqBf 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
