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.
The Open Web Mind is a protocol for shared human intelligence, based on the knowledge hypergraph.
Take a look at this quick introduction for subscribers to The Last Theory, then jump to the 2-minute t…
How big are electrons compared to the hypergraph?
Is one electron formed of 10 nodes, or 10100 nodes?
And if it’s 10100 nodes, might it prove impossible to simulate an electron on any computer we can p…
What if you’re inside a universe, and you want to measure the curvature of space?
It’s important because getting a measure of the curvature of the hypergraph takes us one step further in Jonathan Gora…
In this excerpt from my conversation with Jonathan Gorard, he proposes that particles in Wolfram Physics might be persistent topological obstructions in the hypergraph.
He starts with a toy model in w…
What if you’re inside a universe, and you want to know whether space is curved?
The reason I’m asking is that according to Einstein’s general theory of relativity, our universe is curved, by the prese…
I asked Jonathan Gorard what it felt like when he realized that general relativity can be derived from the hypergraph.
His answer took us in an unexpected direction.
If the Wolfram model is to be an ac…
In my exploration of Wolfram Physics, I’ve come across one objection more than any other.
Over and over again, people have told me that the Wolfram model must be rejected because it makes no predictio…
Here’s a masterclass from Jonathan Gorard.
One of the most compelling results to come out of the Wolfram Physics is Jonathan’s derivation of the Einstein equations from the hypergraph.
Whenever I hear …
Here’s the first of two crucial excerpts from my conversation with Jonathan Gorard.
The core idea of Wolfram Physics is that we can model the universe as a hypergraph. If we want this idea to be taken…
You know peer review, right?
It’s the way academics check each other’s research papers.
It ensures that only the good ones are published and prevents the bad ones from getting through.
Right?
Wrong.
Peer …
“Sorry, this is now getting very metaphysical,” says Jonathan Gorard part way through this excerpt from our conversation.
We start by talking about applying more than one rule to the hypergraph to cre…
It’s pretty easy to see how three-dimensional space might arise from Wolfram Physics.
The hypergraph kinda looks like space, and, for some rules, it kinda looks like it’s three-dimensional.
But our uni…
In the early days of the Wolfram Physics Project, Stephen Wolfram seemed to be seeking a single rule that, when applied to the hypergraph, could generate our universe.
More recently, however, Wolfram …
John von Neumann might be the most important figure in Wolfram Physics prehistory.
Whenever any of the most important prerequisites to Wolfram Physics were happening – quantum mechanics, Gödel’s theor…
The Wolfram model allows an infinite number of rules.
Some of these rules generate interesting universes that are complex and connected, some of these rules generate plausible universes that look a li…
The twentieth century was a truly exciting time in physics.
From 1905 to 1973, we made extraordinary progress probing the mysteries of the universe: special relativity, general relativity, quantum mec…
Causal invariance is a crucial characteristic for any rule of Wolfram Physics.
According to Wolfram MathWorld, if a rule is causally invariant, then “no matter which evolution is chosen for a system, …
Now that I’ve introduced you to the different kinds of edges that might make up a hypergraph – unary, binary and ternary edges, as well as loops and self-loops – we can have some fun.
Some of rules in…
Dugan Hammock creates beautiful animations of three-dimensional cross-sections through four-dimensional spaces.
But his animations aren’t mere mathematical abstractions. He has also applied his geomet…
Causal invariance is one of the most important concepts in the Wolfram model... and one of the most difficult to capture.
So I really wanted to hear Jonathan Gorard’s take on it.
In this excerpt from o…
