The Last Theory - Podcast

The Last Theory

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.

Loops and self‑loops in the hypergraph

Loops and self‑loops in the hypergraph

So many of the most complex and most promising graphs and hypergraphs of Wolfram Physics involve loops and self-loops.

They can play a crucial role in the evolution of graphs and hypergraphs... which …

Living in the fourth dimension with Dugan Hammock

Living in the fourth dimension with Dugan Hammock

Dugan Hammock lives in the fourth dimension.

As Jonathan Gorard mentioned in our recent conversation on How to draw the hypergraph in Wolfram Physics, Dugan has worked on plotting the evolution of the…

Why I changed my mind about computational irreducibility with Jonathan Gorard

Why I changed my mind about computational irreducibility with Jonathan Gorard

Computational irreducibility means that there are no shortcuts when we apply rules to the hypergraph.


I used to think that our existing theories of physics, such as general relativity and quantum mech…

What’s beyond the universe?

What’s beyond the universe?

There are two questions about Wolfram Physics I’m asked a lot:

What’s beyond the hypergraph?

And what’s between the nodes and edges of the hypergraph?

There’s a simple answer to this question.

Nothing.

Th…

How to draw the hypergraph in Wolfram Physics with Jonathan Gorard

How to draw the hypergraph in Wolfram Physics with Jonathan Gorard

The hypergraph is the universe.

So if we want to see the universe, we need only draw the hypergraph.

The question is: how?

The nodes and edges of the hypergraph are determined by the rules of Wolfram Ph…

What is the Big Bang in Wolfram’s universe?

What is the Big Bang in Wolfram’s universe?

What is the Big Bang in Wolfram Physics?

There’s a straightforward answer to that question.

It’s the point in the evolution of the universe where the hypergraph goes from nothing to something.

It’s the …

Graphs v hypergraphs in Wolfram Physics with Jonathan Gorard

Graphs v hypergraphs in Wolfram Physics with Jonathan Gorard

Here’s a slightly technical question:

Does Wolfram Physics really need hypergraphs?

Or could it based on graphs instead?

Jonathan Gorard shares some interesting insights into the evolution of Stephen Wo…

Why hypergraphs might be a good model of the universe with Jonathan Gorard

Why hypergraphs might be a good model of the universe with Jonathan Gorard

Wolfram Physics is based on hypergraphs.

Why?

What is it about hypergraphs that might make them a better model of the universe than, say, strings of characters, or cellular automata, or Turing machines…

Is Wolfram Physics the next scientific revolution?

Is Wolfram Physics the next scientific revolution?

For the last few hundred years, all our theories of physics have been mathematical.

If Stephen Wolfram is right, from now on, our most fundamental theories of physics may be computational.

This shift f…

Why I took a chance on Wolfram Physics with Jonathan Gorard

Why I took a chance on Wolfram Physics with Jonathan Gorard

Jonathan Gorard admits that it was a risk, for his academic career, to work on the Wolfram Physics project.

In this third excerpt from my recent conversation with Jonathan, I asked him how he thought …

What is the multiway graph in Wolfram Physics?

What is the multiway graph in Wolfram Physics?

In Episode 15: Where to apply Wolfram’s rules? (listen to the audiowatch the videoread the article) I introduced a radical idea.

When we’re applying a rule to a graph in Wolfram Physics, there a…

From clockwork to computation in Wolfram Physics with Jonathan Gorard

This is the second of a series of excerpts from my recent conversation with Jonathan Gorard, who was instrumental in the founding of The Wolfram Physics Project.

I asked Jonathan why he found the comp…

Why I don’t like String Theory

Why I don’t like String Theory

In my conversation with Jonathan Gorard about the founding of the Wolfram Physics Project, I said that I don’t like String Theory.

Now, I’ll admit, I don’t really understand String Theory.

It’s highly …

The founding of the Wolfram Physics Project with Jonathan Gorard

The founding of the Wolfram Physics Project with Jonathan Gorard

In 2019, Jonathan Gorard and Max Piskunov goaded Stephen Wolfram into pursuing his ideas for a new kind of science.

This led to the announcement of The Wolfram Physics Project in 2020.

Last week, I tal…

Hypergraphs are everywhere

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, techn…

How big is the computer that runs the universe?

As you’ll know from Episode 8: Where’s the computer that runs the universe? ( readlistenwatch ), I have my doubts about the existence of a computer that’s whirring away, applying Wolfram’s rule…

Unary, binary, ternary, k-ary hyperedges in Wolfram Physics

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: one, two, three, four, seventeen or any other number.

And a hypergraph can include any of …

Where to apply Wolfram's rules?

Confession time: I haven’t been entirely honest with you about applying a rule to a graph in Wolfram Physics.

I’ve explained precisely how to apply a rule, but I’ve been strangely silent when it comes…
