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.
Electrons may be tiny black holes propagating through the hypergraph.
After all, electrons and black holes have much in common: they’re carriers of pure motion, they’re all the same – from the outside…
The multiway graph shows every possible evolution of the universe.
So, if we can compute every possible reality, does that mean that there’s no single objective reality?
Well, the causal graph, it turn…
In this fascinating exposition, Stephen Wolfram connects two of the most important breakthroughs of our time: AI and the ruliad.
I ask Stephen how he thinks about knowledge hypergraphs, which I’m expl…
Can you hold in your mind two different threads of experience?
In this five-minute excerpt from my conversation with Stephen Wolfram, he introduces the strange idea of a multiway mind.
Most of the time…
Fields don’t exist.
I mean, a field with grass in it, that kind of field does exist.
But a field in physics?
A gravitational field? An electric field? A magnetic field? A quantum field?
No such thing.
I’m…
In the previous excerpt from my conversation with Stephen Wolfram, I asked him how I can remain a single, coherent, persistent consciousness in a branching universe.
In this excerpt, we went deeper in…
When the universe branches, we branch with it.
Those branches don’t remain forever apart. They come back together.
So we, as conscious observers, are rescued from splitting into an immense number ever-…
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 ne…
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 stra…
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 fro…
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 o…
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…
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 …
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 equat…
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 causa…
I’ve heard from many of you that you’d like the whole of my conversation with Jonathan Gorard in a single podcast.
So here it is, the complete first interview.
These three hours are a brilliant exposit…
You like Stephen Wolfram, right?
I mean, if he’s to be believed, he has reinvented physics, not to mention philosophy.
How could you not like such a thinker?
Well... it turns out that there are plenty o…
In this final excerpt from our conversation in October 2022, Jonathan Gorard explains how ideas from Wolfram Physics can be applied in fields beyond physics, including biology, chemistry and mathemat…
You know who Stephen Wolfram is, right?
Whether you love him or, you know, don’t love him, there’s no denying that Stephen Wolfram has founded a host of fascinating projects... most of them named Wolf…
I asked Jonathan Gorard the question I’m asked the most: can the Wolfram model make testable predictions about reality, predictions that differ from those of general relativity and quantum mechanics,…
