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.

    Loops and self‑loops in the hypergraph

    Loops and self‑loops in the hypergraph

    So many of the most complex and most promising graphs and hypergraphs of Wolfram Physics involve loops and self-loops.
    They can play a crucial role in the evolution of graphs and hypergraphs... which means that they might play a crucial role in the evolution of the universe itself.
    Loops and self-loops matter, because including them in our models reduces the number of arbitrary assumptions we need to make in Wolfram Physics, making it more complete.

    Living in the fourth dimension with Dugan Hammock

    Living in the fourth dimension with Dugan Hammock

    Dugan Hammock lives in the fourth dimension.
    As Jonathan Gorard mentioned in our recent conversation on How to draw the hypergraph in Wolfram Physics, Dugan has worked on plotting the evolution of the hypergraph over time.
    We get into that in the second part of our conversation, but in this first part, I get to know Dugan as a mathematician and artist.
    Enjoy his amazing animations of three-dimensional cross-sections through four-dimensional hypershapes!

    Why I changed my mind about computational irreducibility with Jonathan Gorard

    Why I changed my mind about computational irreducibility with Jonathan Gorard

    Computational irreducibility means that there are no shortcuts when we apply rules to the hypergraph.
    I used to think that our existing theories of physics, such as general relativity and quantum mechanics, were examples of computational reducibility: shortcuts that allow us to make higher-level generalizations about how the application of rules to the hypergraph gives rise to our universe.
    Jonathan Gorard used to think this, too.
    But it turns out that over the last couple of years, he has changed his mind on this quite radically.
    General relativity and quantum mechanics, he now thinks, aren’t examples of computational reducibility, they’re consequences of computational irreducibility.
    I truly appreciated this part of our conversation, because it radically changed my mind, too, about this crucial concept in Wolfram Physics.

    What’s beyond the universe?

    What’s beyond the universe?

    There are two questions about Wolfram Physics I'm asked a lot: What's beyond the hypergraph? And what's between the nodes and edges of the hypergraph? Here's my response to the age-old question: What's beyond the universe?

    How to draw the hypergraph in Wolfram Physics with Jonathan Gorard

    How to draw the hypergraph in Wolfram Physics with Jonathan Gorard

    The hypergraph is the universe. So if we want to see the universe, we need only draw the hypergraph. The question is: how? Jonathan Gorard and I discuss how to see what's really going on in Wolfram Physics.

    What is the Big Bang in Wolfram’s universe?

    What is the Big Bang in Wolfram’s universe?

    What is the Big Bang in Wolfram Physics? It’s the point in the evolution of the universe where the hypergraph goes from nothing to something. The question is, how does the universe go from nothing to something?
