OCCAM’S RAZOR. “Attempts to understand the release of quantum information from macroscopic black holes in terms of quantum path integrals seem to require very exotic intermediate configurations of multiple wormholes, but these ignore the possibility of a much simpler path integral in a black hole to white hole scenario.” The end of this interesting paper. https://lnkd.in/dUKnus8 View in LinkedIn

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

“VARIABILITY is a hallmark characteristic of quasars. Nearly all quasars vary across the entire electromagnetic spectrum, with the variability amplitude depending on timescale, wavelength, and accretion parameters (e.g., BH mass and accretion rate). This ubiquitous variability encodes critical information about the structure and dynamics of the emitting regions, as well as detailed underlying physics of accretion and feedback processes in these active SMBHs.” (SMBH = super massive black holes; BH = black hole). https://lnkd.in/dEvc7DF View in LinkedIn
