Unary, binary, ternary, k‑ary: hyperedges in Wolfram Physics

Here are answers to some fundamental questions about hypergraphs: a hyperedge can connect any number of nodes, and a hypergraph can include any of these different kinds of hyperedge.

What is a hypergraph in Wolfram Physics?

So far, I've been simulating Wolfram Physics using graphs. But you may have come across simulations of Wolfram Physics using hypergraphs. What's the difference? What is a hypergraph?

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.

Space‑time is dead

Thinking of space and time as effectively the same thing might be the biggest blunder physicists have ever made. Space-time is dead. Here's why... and how physicists got it so wrong for so long.

Is space continuous or discrete?

Has every physicist from Leucippus to Einstein been right to insist that space is continuous? Or is Wolfram right to up-end millennia of settled science and insist that space is discrete?

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.

What are dimensions in Wolfram's universe?

If Stephen Wolfram is right, then our universe might not be uniformly three-dimensional. So maybe dimensionality isn't quite what we think it is. What, exactly, are dimensions?

Are Wolfram's graphs three‑dimensional?

How many dimensions are there in graphs generated by Wolfram Physics? Today I'm going to answer the question. And the answer's going to be unexpected. Here's a hint: it's not two and it's not three.

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?

Where's the computer that runs the universe?

I've been running simulations of our universe on my low-powered laptop. If Stephen Wolfram's right and the real universe evolves computationally in the same way as these simulated universes, where's the computer that runs the universe?

The expanse: dimension, separation & explosion

If it's to be a viable theory of physics, Wolfram Physics has to accurately model space as we know it, including these fundamental characteristics: position, distance, dimension, separation & explosion. Let's see how it measures up.

What is space? the where and the how far

What does our universe look like? Let's start with space. By considering the most fundamental characteristics of space, we can see how the nodes, edges, graphs & rules of Wolfram Physics might accurately represent the world as we know it.

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.

What different rules could be applied to our universe? What different universes would arise from these rules? Here's an exploration of different rules, different universes.

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.

Why I'm writing about Wolfram Physics

If physics and mathematics have always eluded you, well, me too. Here's why I'm writing about Wolfram Physics, despite having lost interest in physics in 1988 and never truly got to grips with mathematics.

A project to find the Fundamental Theory of Physics

The definitive guide to Wolfram Physics. This is a big, beautiful book: over 750 pages of elegant explanation and incredible images illustrating Stephen Wolfram’s progress towards a fundamental theory of physics.

A New Kind of Science

The book that introduced the concepts behind Wolfram Physics. It's a huge book, as we've come to expect from Stephen Wolfram, weighing in at over 1,200 pages, with striking illustrations on almost every one of them.
