The Last Theory Mark Jeffery

 Science
The Last Theory is an easytofollow 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.

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 hypergraph over time.
We get into that in the second part of our conversation, but in this first part, I get to know Dugan as a mathematician and artist.
Enjoy his amazing animations of threedimensional crosssections through fourdimensional hypershapes!

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 mechanics, were examples of computational reducibility: shortcuts that allow us to make higherlevel generalizations about how the application of rules to the hypergraph gives rise to our universe.
Jonathan Gorard used to think this, too.
But it turns out that over the last couple of years, he has changed his mind on this quite radically.
General relativity and quantum mechanics, he now thinks, aren’t examples of computational reducibility, they’re consequences of computational irreducibility.
I truly appreciated this part of our conversation, because it radically changed my mind, too, about this crucial concept in Wolfram Physics.

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? Here's my response to the ageold question: What's beyond the universe?

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? Jonathan Gorard and I discuss how to see what's really going on in Wolfram Physics.

What is the Big Bang in Wolfram’s universe?
What is the Big Bang in Wolfram Physics? It’s the point in the evolution of the universe where the hypergraph goes from nothing to something. The question is, how does the universe go from nothing to something?

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 explains how hypergraphs, rather than graphs, came to be the basis of Wolfram Physics.
