![]() ![]() Relativity, as well as a possible stepping stone for quantum models. The model is not (yet) quantized, but could serve as an interesting setting for analytical approaches to classical general Globally, however, the model is not finite, because solutions tend to generate infinite fractals. This is achieved by limiting ourselves to straight pieces of string, surrounded by locallyįlat sections of space-time. Here, we investigate matter ofĪ form that only displays a finite number of degrees of freedom in compact sections of space-time. That, in any attempt to quantize the theory, ultraviolet divergences are nearly inevitable. Matter interacting classically with gravity in 3+1 dimensions usually gives rise to a continuum of degrees of freedom, so Instead, spacetime seems to be emerging from the rules that connect our "objects" in a categorical sense. By "emergence" I do not understand the type of thermodynamical emergence through which a large observable like pressure emerges from small scale degrees of freedom, hence I do not think spacetime is "made up" of little "space time objects" that are patched together. ![]() This is strange, but understanding the process in which spacetime emerges could explain it. Gravitational observables cannot be bound inside an entanglement wedge or inside an "island" and therefore the normal higher dimensional gravity allows for observables that do not commute with the spacetime metric somewhere "far away". Causal physics produces tensions with such an effect, and entanglement wedges are apparently insufficient. That means information about something inside the black hole should be encoded somehow outside. ![]() The main problem in the black holes information paradox is to figure out a way in which information can get decoded in a region causally far away from where the associated event occurs. ![]()
