  • Summary

  • 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.
