I roughly see how this part (gravitation in the Wolfram Model) works out:
from *Some Relativistic and Gravitational Properties of the Wolfram Model* Jonathan Gorard 1University of Cambridge 2Wolfram Research, Inc The Wolfram Model can be thought of as being an abstract generalization of the “Causal Dynamical Triangulation” approach to quantum gravity developed by Loll, Ambjørn, and Jurkiewicz. The first essential step in the derivation of special relativity for causal-invariant Wolfram Model systems is to make precise the formal correspondence between directed edges connecting updating events in a discrete causal graph, and timelike-separation of events in a continuous Minkowski space (or, more generally, in a Lorentzian manifold). The present article has demonstrated the Wolfram Model to be a novel, exciting and potentially highly fruitful discrete model for spacetime geometry, exhibiting discrete analogs of many (and possibly all) of the salient mathematical features of Lorentzian and pseudo-Riemannian manifolds in limiting cases. There exist a variety of open problems arising from this work, ranging from the possibility of computing higher-order corrections to the discrete Einstein field equations, to determining the computability-theoretic and complexity-theoretic properties that distinguish inertial and non-inertial reference frames, to developing a theory of general relativity that holds in manifolds with variable spacetime dimensions. A few of these problems are discussed in greater depth in our accompanying publication on quantum mechanics, which makes significant use of both the special relativistic and general relativistic formalisms that we develop inthis paper (especially the relationship between confluence, causal invariance and Lorentz covariance, and the derivation of the discrete Einstein field equations), and we intend to investigate several more of these questions in the course of future publications. The present work, however, has at least revealed the Wolfram Model to be a plausible fundamental model for classical relativistic and gravitational physics, and we eagerly await the implications that this will entail. @philipthrift On Wednesday, April 29, 2020 at 2:43:25 PM UTC-5, Philip Thrift wrote: > > > > You will be introduced to the true formulation of the foundations of > physics - which will lead to its unification - leaving behind the deluding > morass of the old mathematical-physics foundations you were brainwashed > with as a student. > > What else? > > @philipthrift > > On Wednesday, April 29, 2020 at 2:14:21 PM UTC-5, ronaldheld wrote: >> >> What will I be getting from reading these long papers? >> Ronald >> >> >> On Wednesday, April 29, 2020 at 4:40:56 AM UTC-4, Philip Thrift wrote: >>> >>> >>> The "hypergraph" stuff from Stephen Wolfram in recent news on his "new >>> foundation" of physics has a name: >>> *The Wolfram Model.* >>> >>> >>> >>> *Some Relativistic and Gravitational Properties of the Wolfram* >>> *Model* >>> Jonathan Gorard >>> >>> https://www.wolframcloud.com/obj/wolframphysics/Documents/some-quantum-mechanical-properties-of-the-wolfram-model.pdf >>> >>> *Some Quantum Mechanical Properties of the Wolfram Model* >>> *Jonathan Gorard* >>> >>> https://www.wolframcloud.com/obj/wolframphysics/Documents/some-relativistic-and-gravitational-properties-of-the-wolfram-model.pdf >>> >>> >>> @philipthrift >>> >> -- You received this message because you are subscribed to the Google Groups "Everything List" group.
