DARK AGES. “It is important to realize that in physics today, we have no knowledge of what energy is.” Nor 95% of the universe which is dark matter and dark energy! " "(Richard P. Feynman, Nobel laureate) https://lnkd.in/dREWUUD View in LinkedIn

SO ENDS this second and last weekend on the relationship of language and mathematics. This subject is hard to investigate, for obvious reasons, but there are clues that can be extrapolated from, and an abundant ability of the human mind to make reasoned speculation. And that is what we have here. View in LinkedIn

NEW PERSPECTIVE, “While the transition to the white hole is still assumed to be on a spacelike hypersurface at a minimum circumferential radius r = a separating the trapped surfaces in the interior of the black hole from the anti-trapped 2-surfaces in the interior of the white hole, I consider alternative scenarios for evolution of the white hole, in which the white hole only emits negative energy for a limited Planck-scale range of retarded time.” https://lnkd.in/dUKnus8 View in LinkedIn

CONTRADICTIONS. “The existence of a black hole event horizon depends on energy conditions that, while reasonable in a classical context, are known to be violated in quantum field theory.” https://lnkd.in/dUKnus8 View in LinkedIn

GOAL. “The main purpose of this paper is to give a more general discussion of how in the quasi-classical framework the black hole can transition to the white hole.” https://lnkd.in/dUKnus8 View in LinkedIn

GUESTS ARRIVING AT A PARTY. “If the late Hawking radiation is entangled with early Hawking radiation rather than with Hawking "partners" inside the horizon, purifying the state for external observers, there are predictions of a "firewall" along the event horizon.” https://lnkd.in/dUKnus8 View in LinkedIn

NEGATIVE ENERGY. “However, prolonged outflow of negative energy to large radii is problematic, since at large radii the energy density violates minimum average energy density theorems proved for quantum field theory in Minkowski spacetime.” https://lnkd.in/dUKnus8 View in LinkedIn

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
