Futurology ~ Liquids On Planets, Black Hole Theory, Space Ceramic, Lying To Robots, Peering Through !!LINK!!



Here there is a diversity of views. Some suggest that this information, too, is radiated away through the Hawking process and the black hole simply disappears. Some suggest that quantum physics makes the event horizon penetrable so that some information is radiated by the Hawking process but some escapes directly. Yet others suggest that the information is copied; one copy is radiated away and the other strikes the singularity, entering a new section of space-time that is causally disconnected from observers outside the black hole, so the two copies never meet.

Theorists have recently developed a number of new theoretical tools to attack the problem and are hard at work. Although the subject lies in the domain of quantum gravity, the implications for other fields, including my own, cosmology, will be profound. The answer will shape any future formulation of the laws of thermodynamics, quantum gravity and unified field theory. Since scrambling information, a.k.a., the entropy, determines the arrow of time, the results may inform us how time may have first emerged at the cosmic singularity known as the big bang. Or, if it proves possible for copies to bounce from the black hole singularity to a separate piece of space time, the same may apply to an even more famous singularity, the big bang. This would lend support to recent ideas suggesting that the large scale properties of the universe were shaped by events before the big bang and these conditions (a form of information) were transmitted across the cosmic singularity into a new phase of expansion. In fact, if information is forever preserved across singularities, the universe may undergo regularly repeating cycles of big bangs, expansion, and big crunches, forever into the past and into the future. To me, a breakthrough with these kinds of implications would be the ultimate game-changer. 350c69d7ab
