ACCESSING THE INTERIOR. “Moreover, during the last few years we have gathered evidence that quantum mechanics allows some access to a black hole’s interior. Ignoring the spacetime behind the horizon is not an option and we have to understand how it emerges holographically.” https://lnkd.in/d3Fw6gf View in LinkedIn

DEFINITION. “Past and future infinity represent complexity equilibrium and the rest of the diagram represents the complexity version of the extreme Boltzmann fluctuation.” (“Time present and time past/Are both perhaps present in time future,/And time future contained in time past.” TSE, Four Quartets). https://lnkd.in/d3Fw6gf View in LinkedIn

THE END OF SPACETIME. “The meaning of the spacetime behind the horizon of a black hole has often been a subject of controversy. One extreme view is that the world simply ends at the horizon; everything else is an unphysical figment. This view leaves unanswered the question of why classical general relativity predicts a smooth global continuation past the horizon.” https://lnkd.in/d3Fw6gf View in LinkedIn

DEFINITION. “The growth of complexity has to do with the growing separation of the initial and evolving states in the complexity metric.” https://lnkd.in/d3Fw6gf View in LinkedIn

BLACK HOLE TRAPDOORS. “We have little or no knowledge about how wormholes evolve over very long periods of time, but we do know something about how complexity evolves. One can hope to leverage this knowledge into a theory of wormhole evolution.” https://lnkd.in/d3Fw6gf View in LinkedIn

BLACK HOLES. “It suggests that there will be no concept of a single classical geometry, but only a quantum super-position of many macroscopically different geometries. The phenomenon of “running out of states” occurs in many contexts including the theory of giant gravitons as well as the theory of Euclidean wormholes.” https://lnkd.in/d3Fw6gf View in LinkedIn

THE END OF PHYSICS. (1894) Albert Michelson + Edward Morley, whose famous experiment refuted the existence of the luminiferous ether, said “that the great principles had already been discovered, and that physics would henceforth be limited to finding truths in the sixth decimal place.” (Just before Einstein unveiled relativity!). https://lnkd.in/dq9jWpt View in LinkedIn

EXHAUSTING KNOWN GEOMETRY. “The classical growth of the black hole interior shown in figure 2 cannot go on forever: the black hole eventually runs out of linearly independent classical geometries, and a transition must occur from the complexity ramp to a complexity plateau.” https://lnkd.in/d3Fw6gf View in LinkedIn

STUCK IN WONDERLAND. “Classical GR governs the interior of an eternal AdS black hole for a tiny fraction of the time. The rare “classical” episodes last for a time ∼ eS and in between them the black hole exists in a vast doubly exponential sea of time, stuck in a state of complexity equilibrium. Very little is known about the geometry of the interior, if indeed it has a geometry, during these periods of equilibrium.” (GR = general relativity). https://lnkd.in/d3Fw6gf View in LinkedIn
