The causal graph is at the core of Wolfram Physics.

It’s crucial to the derivations of Special Relativity, General Relativity and Quantum Mechanics.

And if that’s not enough to convince you that you need to know about the causal graph, how about this:

The causal graph is a reflection of the nature of causality, the nature of objectivity, the nature of reality itself.

Is everything that’s ever going to happen in the universe already determined?

Or does something else – maybe randomness, maybe free will – play a role?

Stephen Wolfram’s answer to this question is straightforward: the ruliad is fully determined.

But there’s a twist. The ruliad is determined, but how we observe the evolution of the universe depends on where we are in the ruliad.

In a fascinating introduction to the role of the observer in the Wolfram model, Stephen touches on some of the deepest philosophical questions in physics, finishing on one of the deepest: is there an objective reality?

Hypergraphs can have any number of dimensions. They can be 2-dimensional, 3-dimensional, 4.81-dimensional or, in the limit, ∞-dimensional.

So how does the three-dimensional space we observe emerge from the hypergraph-based Wolfram model?

Why is space three-dimensional?

Stephen Wolfram’s surprising answer to this questions goes deep into space, time, computation and, crucially, our nature as observers.

Stephen Wolfram reveals that his first major wow along the path towards a fundamental theory of physics was his realization that General Relativity and Quantum Mechanics are the same theory, played out in different kinds of space.

Many other dominos have fallen along the way, from the derivation of Einstein’s equations to applications of the ruliad beyond physics.

But the aspect of Wolfram Physics that Stephen Wolfram himself finds maybe the most compelling is this mirroring of the two pillars of twentieth century physics.

Perhaps General Relativity and Quantum Mechanics aren’t as incompatible as they’ve so long seemed.

In this first excerpt from my conversation with Stephen Wolfram, he tells the story of how he came to apply hypergraphs and hypergraph rewriting rules to the universe itself, and arrived at the first traces of a path towards what might be the last theory of physics.

It feels like everyone has their pet Theory of Everything these days.

So why should you take my preferred Theory of Everything seriously?

Well, give me 5 minutes, and I’ll give you 5 reasons why I find Wolfram Physics more compelling than anything else that’s happened in physics in my lifetime...

...and maybe you’ll want to take it seriously too.

Here’s a question.

Why does the universe exist?

Why is there something rather than nothing?

One of Stephen Wolfram’s boldest claims is that he has the answer.

Let me know whether you’re convinced by his argument!

Do you know what causality is?

If you do, let me know, because I’m not sure.

I’ve never come across a conception of causality that makes sense to me.

After all, our universe seems to follow simple equations like Einstein’s equations, and there’s no mention of causality in these equations.

It makes me think that there’s no such thing as causality.

Unless...

Well, here’s the thing.

I’m no longer sure that our universe does follow these continuous equations.

I’m beginning to think that at the smallest scale, our universe might evolve through discrete computations.

If that turns out to be true, it allows for a limited conception of causalityafter all.

It’s causality, Jim, but not as we know it.

Causal invariance is a crucial concept in Wolfram Physics.

It’s how we get special relativity from the Wolfram model.

It’s how we get quantum mechanics from the Wolfram model.

So what precisely is causal invariance?

This question will take us deep into the multiway graph, to an even deeper question: what is causality?
