| What precisely is causal invariance? | 28 Jul 2024 | 00:15:10 | |
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 causal invariance? This question will take us deep into the multiway graph, to an even deeper question: what is causality? — What is the multiway graph? video ⋅ podcast ⋅ article — The Last Theory is hosted by Mark Jeffery, founder of Open Web Mind I release The Last Theory as a video too!

| How to tell if space is curved | 02 Nov 2023 | 00:11:38 | |
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 presence of matter. If Wolfram Physics is to be a true model of our universe, then the space represented by the hypergraph must also be curved by the presence of matter. Which means that determining whether space is curved is crucial to Jonathan Gorard’s derivation of Einstein’s equations from the Wolfram model. Fortunately, there’s a way to find out that’s so simple that even a crab or a space frog could do it. Here’s how to tell if your universe curved. — Dimensionality:

| How special is general relativity? with Jonathan Gorard | 19 Oct 2023 | 00:06:16 | |
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 accurate model of our universe, then it must give us the Einstein equations. But what if any old model with any old rules can give us the Einstein equations? What if general relativity isn’t so special? This is one of the shorter excerpts from my conversation with Jonathan, but it’s a fascinating one. It takes us to one of the most powerful aspects of the Wolfram model: its ability to answer questions about why our universe is the way it is, questions that were once in the realm of philosophy but may now be within the scope of physics. — Jonathan Gorard

| Why scientific theories need not make predictions | 07 Oct 2023 | 00:13:08 | |
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 predictions. I could respond by saying that Wolfram Physics does make predictions. It predicts Einstein’s equations. It predicts Schrödinger’s equation. But it’s true that it doesn’t make any predictions that differ from those of general relativity and quantum mechanics. At least, not yet. So here’s my more robust response to the objection: all scientific theories make no predictions when they’re first formulated. If we dismiss any new theory solely because it doesn’t make any predictions, then we’d dismiss all new theories. It’s time for academics to learn the lessons of the history of science, and open their minds to bold, new ideas, like Wolfram Physics. — Ideas:

| How to derive general relativity from Wolfram Physics with Jonathan Gorard | 21 Sep 2023 | 00:13:38 | |
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 anyone criticize the Wolfram model for bearing no relation to reality, I tell them this: Jonathan Gorard has proved that general relativity can be derived from the hypergraph. In this excerpt from our conversation, Jonathan describes how making just three reasonable assumptions – causal invariance, asymptotic dimension preservation and weak ergodicity – allowed him to derive the vacuum Einstein equations from the Wolfram model. In other words, the structure of space-time in the absence of matter more or less falls out of the hypergraph. And making one further assumption – that particles can be treated as localized topological obstructions – allowed Jonathan to derive the non-vacuum Einstein equations from the Wolfram model. In other words, the structure of space-time in the presence of matter, too, falls out of the hypergraph. It’s difficult to overstate the importance of this result. At the very least, we can say that the Wolfram model is consistent with general relativity. To state it more strongly: we no longer need to take general relativity as a given; instead, we can derive it from Wolfram Physics. —

| How to derive quantum mechanics from Wolfram Physics with Jonathan Gorard | 07 Sep 2023 | 00:15:34 | |
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 seriously, we’re going to have to derive physics from the hypergraph. The twin pillars of physics, as we know it, are quantum mechanics and general relativity. In this episode, Jonathan explains how quantum mechanics can be derived from the Wolfram model, indeed, how quantum mechanics unexpectedly fell out of the model. It’s a fascinating story. We start with the role of the observer. According to Jonathan, it turns out not to be necessary to narrow our focus to only causally invariant rules. Why not? Because macroscopic observers like ourselves impose causal invariance through our coarse-graining of the hypergraph. In other words, by squinting at the universe, seeing only its large-scale features and glossing over the finer details, we reduce multiple paths through the multiway graph to a single timeline, and, in the process, impose causal invariance. Jonathan goes on to explain that this coarse-graining can be modelled with completion rules. These are fake rules, similar to the true rules of Wolfram Physics, but posited solely to model the coarse-graining of the hypergraph by the observer. And here’s the thing. According to Jonathan, these completion rules are formally equivalent to the collapse of the wavefunction in quantum mechanics. In other words, we finally have an explanation for how the observer causes the collapse of the wavefunction, reducing Schrödinger’s half live, half dead cat to one that’s either dead or alive. If Jonathan’s right, then this is a true breakthrough, not just in quantum mechanics, but in the philosophy of physics. In the next episode, we’ll move on to the other pillar of physics: Jonathan will explain how to derive general relativity from the hypergraph. There’s much more to explain about each of these derivations, but we’re finally getting to the crux of Wolfram Physics, the question of whether it can, after all, model our universe. —

| Peer review is suffocating science | 24 Aug 2023 | 00:14:37 | |
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 review does precisely the opposite of what you think it does. It prevents the good papers from being published, and ensures that only the bad ones get through. Peer review is suffocating science. If we want to reverse the stagnation of science over the last 50 years, then we’ve got to get rid of peer review. —

| Is the universe a tautology? with Jonathan Gorard | 10 Aug 2023 | 00:10:30 | |
“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 create rulial multiway systems. This takes us part way towards applying every possible rule, in other words, towards the ruliad. We move on to the idea of measuring the complexity of a structure in terms of the minimum amount of information needed to express it. Jonathan applies this idea to the ruliad, pointing out that it takes almost no information to express, since it encompasses all possible rules. Since he believes, however, that there is some content to the universe – that it is not a tautalogy – this leads Jonathan to reject the idea of the ruliad. We dig into why he has this intuition is that the universe is not a tautalogy. Jonathan invokes theologians like John Duns Scotus, who promulgated the idea the the world is neither completely reducible nor completely irreducible. He follows the scholastics in steering a middle path, suggesting that there’s enough content in the universe that it’s interesting, but not so much content that we can’t write down well-defined laws of nature. This brings us, for the first time, to the role of the observer in the Wolfram model. Again, Jonathan steers a middle path between placing the computational burden entirely on the universe and placing the computational burden entirely on the observer. I find this 9-minute exposition fascinating. It gets to the heart of some of the philosophical differences between Jonathan Gorard and Stephen Wolfram, and to the nature of the universe and our role as observers. —

| What is a particle in Wolfram’s universe? | 27 Jul 2023 | 00:17:32 | |
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 universe isn’t just empty three-dimensional space. It’s mostly empty space, but there are also particles moving through that space: photons, neutrinos, electrons, quarks. Sometimes, these particles interact, annihilating each other and producing new particles. If Wolfram Physics is to be a successful model of our universe, it must, of course, model these elementary particles and their interactions. So where are the particles in the hypergraph?

| One rule to rule them all? with Jonathan Gorard | 13 Jul 2023 | 00:07:24 | |
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 has promoted the idea of the ruliad, the application of every possible rule to the hypergraph. So I asked Jonathan Gorard, who was instrumental in the founding of the Wolfram Physics Project, whether all rules might be applied to generate our universe, or whether he was searching for one rule to rule them all. — Stephen Wolfram’s 2010 TED talk in which he said he was committed “to see if within this decade we can finally hold in our hands the rule for our universe”.

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 theorem, Turing machines, electronic computers, cellular automata – John von Neumann always seemed to be there. How did John von Neumann always come to be in the right place at the right time to contribute to some of the most significant developments in physics, mathematics and computation history?

| How to find interesting and plausible rules with Jonathan Gorard | 15 Jun 2023 | 00:08:24 | |
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 little like our own, and others... go nowhere. In this excerpt from my conversation with Jonathan Gorard, I ask him how to find rules of Wolfram Physics that are both interesting and plausible. —

| Why has there been no progress in physics since 1973? | 01 Jun 2023 | 00:12:13 | |
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 mechanics, the structure of the atom, the structure of the nucleus, enumerating the elementary particles. Then, in 1973, this extraordinary progress... stopped. I mean, where are the fundamental discoveries in the last 50 years equal to general relativity or quantum mechanics? Why has there been no progress in physics since 1973? For this high-budget, big-hair episode of The Last Theory, I flew all the way to Oxford to tell you why progress stopped, and why it’s set to start again: why progress in physics might be about to accelerate in the early twenty-first century in a way we haven’t seen since those heady days of the early twentieth century. — Eric Weinstein’s claims that there has been no progress in physics since 1973: — I release The Last Theory as a video too!

| How to find causally invariant rules with Jonathan Gorard | 18 May 2023 | 00:05:13 | |
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, the history is the same, in the sense that the same events occur and they have the same causal relationships.” Causal invariance is one of the assumptions Jonathan Gorard needs to make to derive the equations of General Relativity from the hypergraph. That’s how crucial it is! Given that not every rule of Wolfram Physics is causally invariant, I asked Jonathan how we find the ones that are. Here, in another excerpt from our recent conversation, is his answer: how to find causally invariant rules. — Jonathan Gorard

| Causal invariance versus confluence with Jonathan Gorard | 08 Apr 2023 | 00:13:29 | |
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 our conversation, Jonathan addresses the differences between causal invariance and confluence. Causal invariance means that regardless of the order in which a rule is applied to the hypergraph, the same events occur, with the same causal relationships between them. Confluence, on the other hand, is the coming-together of different branches of the multiway graph. Jonathan explores different ways we might determine whether two nodes, two edges or two hypergraphs are the same, and explains that if we identify nodes and edges according to their causal histories, then causal invariance and confluence become the same idea. I’ve found myself listening to Jonathan’s explanation of causal invariance over and over to make sense of it, but it’s one of the areas where I’m convinced Jonathan has a unique contribution to make. — Jonathan Gorard • Jonathan Gorard at The Wolfram Physics Project • The Centre for Applied Compositionality

| Loops and self‑loops in the hypergraph | 26 Mar 2023 | 00:10:53 | |
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 means that they might play a crucial role in the evolution of the universe itself. Loops and self-loops matter, because including them in our models reduces the number of arbitrary assumptions we need to make in Wolfram Physics, making it more complete. – I release The Last Theory as a video too!

| How to draw the hypergraph in Wolfram Physics with Jonathan Gorard | 26 Jan 2023 | 00:08:06 | |
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 Physics. But how we draw those nodes and edges is not determined. The drawing of the hypergraph is not the universe, it’s just a way of visualizing the universe. So I asked Jonathan Gorard how we might decide where to position the nodes and edges when we draw the hypergraph, so that we can see what’s really going on in Wolfram Physics. —

| Graphs v hypergraphs in Wolfram Physics with Jonathan Gorard | 05 Jan 2023 | 00:06:50 | |
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 Wolfram’s model for a fundamental theory of physics. Wolfram started with trivalent graphs, in which each edge joins two nodes, and each node has three edges. But when he ran into issues implementing simulations using these simple graphs, he solved the problem by graduating to hypergraphs, in which each hyperedge can join any number of nodes, and each node can have any number of hyperedges. Here’s how hypergraphs, rather than graphs, came to be the basis of Wolfram Physics. — Jonathan Gorard

| Is Wolfram Physics the next scientific revolution? | 15 Dec 2022 | 00:10:53 | |
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 from mathematics to computation feels to me like a scientific revolution. Recently, I asked Jonathan Gorard, who was instrumental in the founding of The Wolfram Physics Project, whether it feels to him, too, like a scientific revolution. “I think so,” he said. “I mean, it’s a strong statement, but I don’t think it’ll end up being too inaccurate.” (If you want to check out that part of our conversation, you can listen here or watch here.)

| Why I took a chance on Wolfram Physics with Jonathan Gorard | 08 Dec 2022 | 00:09:18 | |
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 about that risk and why he decided to take it. He told me that the opportunity to work with Stephen Wolfram on this new model is a bit like being given an opportunity to work with von Neumann and Ulam on cellular automata, or with Turing, Church and Gödel on computational models, back in the early twentieth century. So I asked Jonathan whether he thought, as I do, that the reframing physics in terms of computation feels like we’re in a scientific revolution, as important as the reframing of physics in terms of mathematics several hundred years ago. “It’s a strong statement,” he replied, “but I don’t think it’ll end up being too inaccurate.” For me, the opportunity to talk to Jonathan about Wolfram Physics feels a bit like being given an opportunity to interview Dirac, Heisenberg, Pauli or Schrödinger back in the early days of quantum mechanics. These are exciting times. —

| What is the multiway graph in Wolfram Physics? | 01 Dec 2022 | 00:12:30 | |
In Episode 15: Where to apply Wolfram’s rules? (listen to the audio ⋅ watch the video ⋅ read the article) I introduced a radical idea. When we’re applying a rule to a graph in Wolfram Physics, there are generally many possible places in the graph we could apply the rule, giving us many possible next states of the universe. Here’s the radical idea: rather than choose one of these possible universes, we choose not to choose. Instead, we keep each of them in mind. The trouble is, if we choose not to choose, the number of possible universes we have to keep in mind gets extremely large extremely quickly. To help us visualize all these possible universes, we’re going to need the multiway graph It’s a crucial idea in Wolfram Physics. The multiway graph will allow us to derive aspects of quantum mechanics from Wolfram Physics. It’ll lead us to a concept of the observer that promises to resolve issues related to the collapse of the wavefunction that have plagued quantum mechanics ever since Schrödinger put his metaphorical cat into a metaphorical cage. And maybe, just maybe, it’ll lead us to a model of consciousness itself. – I release The Last Theory as a video too! Watch here. The full article is here. Kootenay Village Ventures Inc. | |||

| The founding of the Wolfram Physics Project with Jonathan Gorard | 03 Nov 2022 | 00:14:30 | |
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 talked to Jonathan Gorard about the revolutionary ideas that have come out of the project. In this first excerpt from our conversation, Jonathan talks about his instrumental role in the founding of The Wolfram Physics Project. We cover why the time was right in 2020... and why it had been wrong in 2002 when Stephen Wolfram published his book A New Kind of Science. We talk about how Wolfram Physics might take over from string theory, why Jonathan likes string theory... and why he doesn’t. It was a true pleasure to talk to Jonathan about what might prove a pivotal moment in the history of science. —

| Hypergraphs are everywhere | 27 Oct 2022 | 00:08:45 | |
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, technology. What I want to know is: Why? Why are hypergraphs everywhere? —

| How big is the computer that runs the universe? | 13 Oct 2022 | 00:16:27 | |
As you’ll know from Episode 8: Where’s the computer that runs the universe? ( read ⋅ listen ⋅ watch ), I have my doubts about the existence of a computer that’s whirring away, applying Wolfram’s rules to Wolfram’s graphs, performing the computations required to run our universe. This computer, if it exists, is necessarily invisible to us, and as I warned in Episode 12: Beware invisible things ( read ⋅ listen ⋅ watch ) we should be wary of what we can’t see. Still, I want to revisit this idea of a computer that runs the universe. I want to come at it from a slightly different direction. Rather than adopt the stance of the monkey with its hands over its eyes and insist that if I can’t see it, it’s not there, let’s suppose that there is a computer that runs the universe and ask a simple question: How big would it have to be?

| Unary, binary, ternary, k-ary hyperedges in Wolfram Physics | 29 Sep 2022 | 00:09:44 | |
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 these different kinds of hyperedge, or all of them. Let’s take a look at what this means for Wolfram Physics... and at some of the beautiful hypergraphs it allows us to generate! I release The Last Theory as a video too! Watch here.

| Where to apply Wolfram's rules? | 02 Sep 2022 | 00:12:57 | |
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 to where to apply the rule. I know, it’s unlike me to be silent, right? Time to come clean. It turns out that the question of where to apply Wolfram’s rules is not as easily answered as you might think. This seemingly straightforward question will take us into the philosophy of time, causality, consciousness, contingency and determinism. And it’ll lead us towards some of the most important concepts in Wolfram Physics: the multiway graph, branchial space and causal invariance. Check your breathing apparatus: we’re going deep.

| Space-time is dead | 04 Aug 2022 | 00:12:18 | |
In his General Theory of Relativity, Einstein combined the three dimensions of space with the one dimension of time in what we now know as Einstein’s equations. Ever since, physicists have thought of space and time as effectively the same thing: components of four-dimensional space-time. This might be the biggest blunder physicists have ever made. Stephen Wolfram, on page 22 of his book A project to find the Fundamental Theory of Physics, calls it the “one ‘wrong turn’ in the history of physics in the past century”. Space-time is dead. Here’s why... and how physicists got it so wrong for so long. I release The Last Theory as a video too! Watch here. The full article is here. Kootenay Village Ventures Inc. | |||
| Is space continuous or discrete? | 21 Jul 2022 | 00:09:06 | |
We’re used to thinking of space as continuous. A stone can be anywhere in space. It can be here. Or it can be an inch to the left. Or it can be half an inch further to the left. Or it can be an infinitesimal fraction of an inch even further to the left. Space is infinitely divisible. The graphs of Wolfram Physics, however, are discrete. If, as Stephen Wolfram proposes, the universe is a graph, then you can’t be just anywhere in space. It makes sense to think about a node of the graph as a position in space. It makes no sense to think about anywhere in between the nodes as positions in space. This space is not infinitely divisible. It’s as if a stone could be here in space, or here in space, but nowhere in between. So which is it? Has every physicist from Leucippus to Einstein been right to insist that space is continuous? Or is Wolfram right to up-end millennia of settled science and insist that space is discrete? I release The Last Theory as a video too! Watch here. The full article is here.

| Beware invisible things | 07 Jul 2022 | 00:10:44 | |
We humans have always been fond of invisible things. Poltergeists, fairies, unicorns, the Yeti, the Lost City of Atlantis. Just because you can’t see them, it doesn’t mean they aren’t there. Scientists, no less than any other humans, suffer from this fondness for invisible things. Phlogiston, miasma, ether, strings. Just because you can’t see them, scientists have insisted, it doesn’t mean they aren’t there. Beware these invisible things. As I explore Wolfram Physics, I’m aware of certain invisible things that we believe in now, but we’re going to have to let go, if Stephen Wolfram is right. And I’m also aware of the temptation to replace this old set of invisible things with a new set of invisible things. Here’s why we’d do well to resist. I release The Last Theory as a video too!

| What are dimensions in Wolfram’s universe? | 09 Jun 2022 | 00:11:39 | |
We know what it means when we say that our universe is three-dimensional: it means that we can move in three orthogonal directions: left-right; up-down; forwards-backwards. But what would it mean to say that a universe is 2½-dimensional? Or 3.37-dimensional?

| Where's the evidence for Wolfram Physics? with Jonathan Gorard | 19 Jan 2024 | 00:14:32 | |
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, predictions that might prove that Wolfram Physics is right? Jonathan showed how the Wolfram model might shed light on some of the most mysterious phenomena of our universe, from black hole inspirals to quantum entanglement. He focused on four areas where the class of theories encompassed by the Wolfram model might predict observable phenomena: 1. Cosmological consequences of global dimension change 2. Astrophysical consequences of local dimension change 3. Discretization effects during extreme astrophysical events 4. Quantum mechanical effects such as maximum entanglement speed These dozen minutes of my conversation with Jonathan were dense with insights into Wolfram Physics, a true pleasure to revisit! — Jonathan Gorard

| Are Wolfram’s graphs three‑dimensional? | 26 May 2022 | 00:14:48 | |
Are Wolfram’s graphs three-dimensional? In Episode #009: How to measure the dimensionality of the universe – watch the video or read the article – I introduced a mathematically-minded crab, which was able to determine the dimensionality of its universe by measuring how much space it covered moving different distances in every possible direction. Now I’m going to use the same crabby method to determine the dimensionality of graphs generated by Wolfram Physics. I’m finally going to answer the question: how many dimensions are there in one of Wolfram’s universes? And the answer’s going to be unexpected. Here’s a hint: it’s not two and it’s not three. 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. Kootenay Village Ventures Inc. | |||
| How to measure the dimensionality of the universe | 12 May 2022 | 00:09:45 | |
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? | 28 Apr 2022 | 00:11:49 | |
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.

| The expanse: dimension, separation & explosion | 14 Apr 2022 | 00:09:39 | |
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!
