Ashtekar, Olmedos and Singh's new equations describe black holes in loop quantum gravity and showed that black hole singularity does not exist. "In Einstein's theory, space-time is a fabric that can be divided as small as we want. This is essentially the cause of the singularity where the gravitational field becomes infinite. In loop quantum gravity, the fabric of space-time has a *tile-like structure*, which cannot be divided beyond the smallest tile. My colleagues and I have shown that this is the case inside black holes and therefore there is no singularity," Singh said. "These tile-like units of geometry--called 'quantum excitations'-- which resolve the singularity problem are orders of magnitude smaller than we can detect with today's technology, but we have precise mathematical equations that predict their behavior," said Ashtekar, who is one of the founding fathers of loop quantum gravity.But is this consistent with https://arxiv.org/abs/1109.5191v2 which showed spacetime to be smooth down to 1/525 of the Planck length? Brent, Wouldn't this be a successful prediction of Bruno's theory? In another thread you said it had only made retrodictions, but wasn't one of Bruno's predictions that space and time would be continuous (not discrete), therefore it would predict LQG is false, and then https://arxiv.org/abs/1109.5191v2 would be a confirmation of that. How did Bruno predict that from a digital (integral) model)?https://groups.google.com/d/msg/everything-list/zq6LVIjhrn0/kVZao94IeGkJ(A post from 2007, citing his work from 2004)The essential idea is that the first person experience of a physicalworld, and of making predictions or measurements involves infinitenumbers of competing programs going through and realizing the state ofthe observer's mind at one point in time. Predicting what happensnext, the outcome of an experiment, a measurement of a particle'slocation, etc. involves the statistics concerning the infinity ofthese programs. It means the physical appearances/physical universe isitself not computable (not without infinite time and resources), andthis implies a continuum somewhere in physics. (i.e. eechanism isincompatible with digital physics)

Being not computable is not the same as being a continuum.

And where did he make such a prediction?https://groups.google.com/d/msg/everything-list/2numMVaxsJ0/QePUwROUln4J(post from 2007, explaining the continuum)https://groups.google.com/d/msg/everything-list/yKiXo8jB7VY/VxqraVyz5c4J(post from 2009, describing that physics cannot be entirelycomputational if "I am a machine")https://groups.google.com/d/msg/everything-list/QuedsKrpW4g/C6pAbJItvfMJ(post from 2009, pointing out that if digital physics is true, thenmechanism would be refuted)Jason --You received this message because you are subscribed to the GoogleGroups "Everything List" group.To unsubscribe from this group and stop receiving emails from it, sendan email to everything-list+unsubscr...@googlegroups.com<mailto:everything-list+unsubscr...@googlegroups.com>.To post to this group, send email to everything-list@googlegroups.com<mailto:everything-list@googlegroups.com>.Visit this group at https://groups.google.com/group/everything-list.
