    Where's the evidence for Wolfram Physics? with Jonathan Gorard

    Where's the evidence for Wolfram Physics? with Jonathan Gorard

    I asked Jonathan Gorard the question I’m asked the most: can the Wolfram model make testable predictions about reality, predictions that differ from those of general relativity and quantum mechanics, predictions that might prove that Wolfram Physics is right?
    Jonathan showed how the Wolfram model might shed light on some of the most mysterious phenomena of our universe, from black hole inspirals to quantum entanglement.
    He focused on four areas where the class of theories encompassed by the Wolfram model might predict observable phenomena:
    1. Cosmological consequences of global dimension change
    2. Astrophysical consequences of local dimension change
    3. Discretization effects during extreme astrophysical events
    4. Quantum mechanical effects such as maximum entanglement speed
    These dozen minutes of my conversation with Jonathan were dense with insights into Wolfram Physics, a true pleasure to revisit!

    Are electrons too big to simulate? with Jonathan Gorard

    Are electrons too big to simulate? with Jonathan Gorard

    How big are electrons compared to the hypergraph?
    Is one electron formed of 10 nodes, or 10100 nodes?
    And if it’s 10100 nodes, might it prove impossible to simulate an electron on any computer we can possibly imagine?
    When I asked Jonathan Gorard this question, he took us on a tour of the scales of the universe, from the Planck scale to the Hubble scale.
    He revealed how the Wolfram Physics Project’s early estimate of the scale of the hypergraph was based on a tower of rickety assumptions.
    And he explained how the Wolfram model might connect with particle physics regardless of the disparities of scale.

    How to measure the curvature of space

    How to measure the curvature of space

    What if you’re inside a universe, and you want to measure the curvature of space?
    It’s important because getting a measure of the curvature of the hypergraph takes us one step further in Jonathan Gorard’s derivation of General Relativity from Wolfram Physics.
    Einstein’s equations relate the curvature of space to the presence of matter. So if we’re going to prove that Einstein’s equations follow from the Wolfram model, we’re going to need that measure of the curvature of the hypergraph.
    Once again, a two-dimensional crab comes to the rescue, given us a way to measure the curvature of a universe from inside that universe.

    See Stephen Wolfram’s announcement, under Curvature in Space & Einstein’s Equations, also included as the introduction to his book A project to find the Fundamental Theory of Physics, page 20, for more on measuring the curvature of space

    A toy model of particles with Jonathan Gorard

    A toy model of particles with Jonathan Gorard

    In this excerpt from my conversation with Jonathan Gorard, he proposes that particles in Wolfram Physics might be persistent topological obstructions in the hypergraph.
    He starts with a toy model in which elementary particles are non-planar tangles moving and interacting in an otherwise planar hypergraph.
    But he doesn’t stop there.
    He explains that there’s an infinite variety of hypergraphs that give rise to such persistent topological obstructions.
    These localized tangles behave in ways that look a lot like particle physics.
