Well, there is an interesting revolution happening in science right now. It's quite stunning. The assumption that space and time are fundamental or their combination, space, time is fundamental, has been a very valuable and useful foundational idea for many, many decades. Centuries, actually. High energy theoretical physicists, though, have realized that spacetime cannot be fundamental. It falls apart at the Planck scale. So we know exactly where it ceases to make sense. It doesn't make sense at 10 to the -33 centimeters and 10 to the -43 seconds. So it's not that, you know, some cognitive scientist is saying we need to think out of the box. I'm just listening to what the physicists are saying, the high energy theoretical physicists, and they're saying we need to find a new framework that's outside of space time. And they're going after it. Right, there's. The European Research council has a 10 million euro initiative on these positive geometries beyond space time that the physicists are now studying. So it's not like some maverick cognitive scientist is the first to say, hey, this is over for space time. No, I'm cheering on what the high energy theoretical physicists have been saying for quite a while. But I'm saying we need to look outside of physical categories, perhaps now space time kinds of categories. And that's hard to do. I mean, this is requiring real big leaps. So what the physicists are finding are these positive geometries. They're just static objects. They're like monoliths outside of space time. And their shapes and volumes code for particle interactions inside spacetime. Remarkably, they actually give you the probabilities for various kinds of particle interactions. But why, you know, is anybody's guess about why these things are doing that and so forth. So we don't have a good framework of what's outside of spacetime. I mean, that's the big question. If space time isn't fundamental first, what could that possibly mean? What could possibly be outside of space time? That's the first question most of us go, spacetime is the foundation of reality. What are you even talking about? So the physicists are saying, whatever space time is, it falls apart at blank scale. So we have to find something outside of spacetime. And it's anybody's guess what it is. Now, spiritual traditions, of course, have been there for thousands of years. They've been saying spacetime is not, or space and time are the final reality. There's something well beyond space and time. And they've had techniques like meditation and so forth to help you to sort of transcend the notion of space time. So both sides have had a piece of the puzzle. The physicalists, the scientists have had the rigor of mathematical models, and the spiritual people have had the idea that space and time aren't fundamental, that there's something deeper than that. But they've not had any mathematical tools. They've only had intuitive tools and so forth. And we can see this coming together historically with Galileo and the Church, right? So here we have the clashing of the two world approaches where the church, the Catholic Church at the time, said that they had the authority of miracles and that everybody should submit because they had the authority of Mary. And Galileo was saying, no, I've got mathematics and experiments, and mathematics and experiments overrule whatever you might claim on your authority. And so there's Been this division ever since, right? Because you know, the church put Galileo under house arrest, he died under house arrest and he was forced to recant his scientific views about the earth not being the center of the universe. Well, you know, in retrospect the church agreed they were wrong and they apologized. Right? So but it took four centuries or something like that for them to apologize. But science and spirituality really diverged then and we've seen them go separate paths. And for a while it was sort of, you know, important to diverge because you really needed to establish something separate from authority. You needed to have math and experiments. But now we're at this interesting intersection where high energy theoretical physics is now saying oh, now we agree that there's something beyond space time and what is it we're finding these positive geometries, these obelisks, but what do they mean? And the spiritual traditions still don't have any mathematical tools. So here's the position we're in. It seems like science has one part of the puzzle. We have mathematical models and we have experiments. This is how you make progress and really understanding things. The spiritual traditions say we understand that there's something beyond space time. And the physicists are now saying yeah, I think there is something beyond space time. How can we try to put these two pictures together? So that's where science is right now and where spirituality is. So to summarize, the spiritual trad are outside of space time, but there's no math and there's no experiments. Now someone might say well yeah, there are experiments looking for like anomalous phenomena and so forth. And yeah, I have friends who are scientists who are looking for psi phenomena and so forth. But any hard nosed scientist is going to say experiments without a theory aren't going to move me very much. If you are doing these psi experiments and you're finding these anomalous results, I want you to first give me a theory that predicts the exact values of the anomalous results that you're getting. Otherwise, what can I say except maybe you made a mistake. If you have a theory that predicts something to the, you know, eight decimal places and you get that eight decimal place result and the other then the scientific theories around can't do it and a couple other labs replicate you. But then of course scientists are going to pay attention, right? But just to say I've got something that doesn't fit in, they're not going to pay attention. So what the spiritual traditions and those thinking outside of spacetime idealists, for example, have lacked is a rigorous mathematical model that makes testable predictions from outside of space time. And what the physicalists understand now is we have to go beyond space time. And they're doing rigorous mathematical models, but they don't know what they mean. These are positive geometries, but who ordered them? Right, it's who ordered this? I wanted to get the best of both. I want to use absolute hard nosed mathematical models and experiments from the scientific side, no nonsense, but I want to step outside of space time and take the idea that consciousness is fundamental quite seriously. So that means no hand wave. Give me a mathematical model of conscious experience, period. And with that mathematical model give me exactly how space time can arise again. Precisely. So how does Einstein's Minkowski space, the flat space time of Einstein come out of this? Or how does the curved spacetime of Einstein come out of this? And general relativity? And how does quantum mechanics come out of this? Because when space time is doomed, so is quantum theory. Quantum fields for example, are defined over spacetime. So just not enough to say, oh yeah, so we're going to go quantum on this. That's not enough. When you go quantum you're still stuck with spacetime. Quantum fields are defined over space time. And if you're in non quantum field theory, if you're just doing standard Schrodinger evolution, then you've got time as a parameter, an explicit parameter, and so you're stuck in time. So it's not enough to say we're going quantum, that that gets you not out of space time. So we have to really think out of the box. Right? So space time is doomed. Now I'm quoting physicists like Nima Arkani Hamed and David Gross. So this is not just a cognitive scientist saying this. I'm just quoting some high energy theoretical physicists who say spacetime is doomed. And they'll say explicitly that means quantum theory isn't fundamental either. So we have to go outside of space time and quantum theory together. And that doesn't. So many of the in the spiritual traditions who are trying to go to the next step are still holding on to quantum theory. And I'm saying you hold on to quantum theory, you're holding on to a dead horse. This is, you've got to go beyond quantum theory.
