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. On The Last Theory podcast, I investigate the implications of Wolfram's ideas and dig into the details of how his universe works. Join me for fresh insights into Wolfram Physics every other week.

How to measure the dimensionality of the universe

Today’s episode includes a lot of visuals, so I recommend you watch the video or read the article rather than listen to the audio.
In Episode #007: The expanse: dimension, separation & explosion – watch the video or read the article – I argued that 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 these graphs are three-dimensional? Many of them are so convoluted that it’s difficult to tell whether they’re two-dimensional, three-dimensional or somewhere in between.
I’m going to make the question even more difficult. We’ve been looking at graphs from the outside, from a God’s-eye view.
In reality, though, we’re not outside the graph. Remember, we’re hoping that the graphs of Wolfram Physics will prove to be a true representation of our universe, and we can’t be outside our own universe.
How could we tell whether a graph is two-dimensional, or three-dimensional, or even two-and-a-half-dimensional, from inside the graph?
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, according to Stephen Wolfram’s computational theory of physics.
Where’s the computer that runs these simulations?
Well, it’s right here. This a low-powered laptop in my hand is literally the computer that runs these universes.
It’s natural to ask a follow-up question.
If 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?
I release The Last Theory as a video too! Watch here.

The expanse: dimension, separation & explosion

In the last episode, I introduced two fundamental characteristics of space: position and distance.
Today, I’m going to introduce three more characteristics of space: 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 all five of these characteristics.
Let’s see how it measures up.

In the episode, I refer back to Episode #006: What is space? the where and the how far. Again, I recommend you watch the video or read the article rather than listen to the audio for that episode, since you’ll want to see the visuals!

What is space? the where and the how far

What is space in Wolfram Physics?
I’ve talked about the basic concepts of Wolfram Physics: nodes, edges, graphs & rules.
I just threw these concepts out there. No explanation. No rhyme, no reason. Nodes, edges, graphs & rules. Take them or leave them.
Naturally, this raised a few questions in some people’s minds.
These questions can be summed up as follows:
Wait... What? Nodes, edges, graphs & rules? Why?
This a deep question.
Let’s get into it.

In this episode, I refer back to Episode #004: Different rules, different universes. This one, too, includes a lot of visuals, so again, I recommend you watch the video or read the article rather than listen to the audio for that episode.
I also refer to a Polynesian stick chart. You can find it here: Micronesian navigational chart.

What is physics? the how and the why

I like being asked questions about Wolfram Physics.
When I try to answer them, though, I often find myself trapped in an infinite regress.
To address a question about Wolfram Physics, I might first need to address another, more fundamental question, about physics.
And to address that question, I might first need to address another, more fundamental question, than might be more philosophy than physics.
Today, I’m going to go to one of those deep questions that need to be asked, if not answered, before I can begin to address many of the questions I’ve been asked about Wolfram Physics.

Different rules, different universes

It’s all about the animations.
I’ve been coding coding coding the few weeks to develop my simulations of Wolfram Physics.
So now I’m able to explore a number of simple rules and ask a number of simple questions.
What different rules could be applied to our universe?
What different universes would arise from these rules?
Today, I explore different rules, different universes.
Today’s episode includes a lot of visuals, so you might prefer to read the article, or watch the video, where they’re fully animated.

Why you’ve never heard of Wolfram Physics

Wolfram Physics might be the most fundamental scientific breakthrough in your lifetime.
And yet you’ve probably never heard of it.
Here’s why.

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

Are you ready?
Today, I’m going to dive right into Wolfram Physics.
If you’ve never heard of Stephen Wolfram or his team’s project to find the fundamental theory of physics, don’t worry.
Think of it like this: I’m going to dive right into the fundamental structure of the universe.
And, well, you might not believe that the words “simple” and “physics” can go together, but I’m going to keep it simple.
Today’s episode includes a lot of visuals.
You can find them in the article, or you might want to switch to watching the video, where they’re fully animated.

Why I’m writing about Wolfram Physics

I always envy those people who, through a fantastic stroke of luck, find themselves to be exactly the right person in exactly the right place at exactly the right time to seize a once-in-a-lifetime opportunity.
I always ask myself, why can’t that happen to me?
Well, it just did.
Let me explain.
In this week’s episode, I discuss why I’m writing about Wolfram Physics.
I’ll be digging into the details, as well as taking a step back to see some of the philosophical implications, in future episodes.
