The Last Theory is an easy-to-follow exploration of what might be the last theory of physics. In 2020, Stephen Wolfram launched the Wolfram Physics Project to find the elusive fundamental theory that explains everything. On The Last Theory podcast, I investigate the implications of Wolfram's ideas and dig into the details of how his universe works. Join me for fresh insights into Wolfram Physics every other week.© Kootenay Village Ventures Inc. 2022 Ciencia Física

  • Ruliad + observer = physics ... also aliens
    Dec 18 2025

    The ruliad is every possible computation. What could you possibly say about such an enormous, all-encompassing object?

    Well, that’s where we come in.

    Particular observers sample the ruliad in particular ways.

    Observers like us sample the ruliad in ways that give rise to physics as weknow it.

    Ruliad + observer = physics.

    In this excerpt from my conversation with Stephen Wolfram, he explores how physics, mathematics and biology all arise from this same enormous, all-encompassing object, the ruliad.

    He gets to aliens, too, asking such provocative questions as how far from us in rulial space are the nearest aliens?

  • How to simplify the causal graph
    Dec 11 2025

    The hypergraphs generated by Wolfram Physics are complex and chaotic.

    The multiway graphs that trace every possible evolution of these hypergraphs become extremely complex and extremely chaotic after only a few iterations.

    The causal graphs that plot which of the events in these multiway graphs has to happen before which of the other events look like spaghetti.

    If we’re going to find mass/energy or momentum in Wolfram Physics – or special relativity or general relativity or quantum mechanics – then the causal graph is the place to look.

    But if we’re going to have to find all of physics in a causal graph that looks like spaghetti, then I give up.

    If we’re going to find all of physics in the causal graph, then we’re going to have to simplify.

    How to simplify the causal graph?

    Two ways:

    • use a simpler rule; and
    • collapse multiple nodes representing the same event into a singlenode.

    Don’t worry, by the time we’re done, that’ll all make sense!

    This is the pivotal episode in my exploration of Wolfram Physics. It establishes a firm foundation what comes next. From here on, we’ll be able to make serious progress... towards mass/energy, momentum, special relativity, general relativity and quantum mechanics.

  • Where's Mark?
    Nov 15 2025

    It’s been a while since my last episode of The Last Theory or Open Web Mind.

    Where am I?

    It might look like I’m lazing in the sun, but actually I’ve been working hard.

    For The Last Theory, I’ve been working on a long episode, more involved than any I’ve ever made, and more important than any I’ve ever made.

    It’ll unlock mass/energy, momentum, special relativity, general relativity and quantum mechanics.

    And I’ve been working on Open Web Mind, too, making serious progress towards launch.

    So I’m sorry for the delay, but it’ll be worth the wait.

    In the meantime, make sure you’re subscribed to my newsletters at lasttheory.com and openwebmind.com to be the first to know when the train’s leaving the station.
