How to draw the hypergraph in Wolfram Physics

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 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?

Graphs v hypergraphs in Wolfram Physics

Here's a slightly technical question: Does Wolfram Physics really need hypergraphs? Or could it based on graphs instead? Jonathan Gorard explains how hypergraphs, rather than graphs, came to be the basis of Wolfram Physics.

Nodes, edges, graphs & rules: the basic concepts of Wolfram Physics

According to Wolfram Physics, the universe is a network of points and lines. Here's my simple explanation of nodes, edges and graphs, along with rules, which determine how the universe evolves.

What is physics? the how and the why

I pick up a stone. I hold it in my hand, my palm over the stone, my fingers curled underneath. I let go. The stone falls. Why? This one-word question takes us to the heart of what physics is. And, perhaps more importantly, what physics isn't.

How to measure the dimensionality of the universe

The graphs of Wolfram Physics are going to have to be three-dimensional to be a true representation of our universe. But how can we tell whether they're three-dimensional? How would we measure the dimensionality of our own universe?

Beware invisible things

As I explore Wolfram Physics, I'm aware of certain invisible things that we believe in now, but we're going to have to let go, if Stephen Wolfram is right. And I'm also aware of the temptation to replace this old set of invisible things with a new set of invisible things. Here's why we'd do well to resist.

Where to apply Wolfram's rules?

The question of where to apply Wolfram's rules is not as easily answered as you might think. This seemingly straightforward question will take us into the philosophy of time, causality, consciousness, contingency and determinism. And it'll lead us towards some of the most important concepts in Wolfram Physics: the multiway graph, branchial space and causal invariance.

Hypergraphs are everywhere

Wolfram Physics models the universe as a hypergraph. Maybe I'm just seeing things, but it seems to me that hypergraphs are everywhere: physics, chemistry, biology, neurology, ecology, sociology, technology. What I want to know is: Why? Why are hypergraphs everywhere?
