Tom Bilyeu's Impact Theory

Is Reality Real? - New Science On How The Universe & Consciousness Aren't Real | Donald Hoffman PT 2 (Fan Fav)

01 Jan 2026

Transcription

Chapter 1: What is the main topic discussed in this episode?

3.119 - 18.039 Tom Bilyeu

Welcome back for part two with the mind-bending cognitive scientist Donald Hoffman. If you heard part one, you already know Donald believes we're all living in a simulation, for real, a straight-up video game. He believes he can prove all of this with mathematics.

0

18.42 - 38.452 Tom Bilyeu

His belief is that consciousness is the fundamental element of nature, and Einstein's idea of spacetime is an illusion that arises from the simulation. He believes that the mind creates the body, not the other way around. Every time I talk to Donald, he blows me away and I'm always wondering if he might actually be right.

71.266 - 110.667 Tom Bilyeu

It's time for part two of Donald Hoffman. I'm your host, Tom Bilyeu, and welcome to Impact Theory. So I'm just trying to understand. So the thing that I'm sort of debating in my own head is, okay, when I grant you that consciousness is fundamental, then there's all this internal logic to the space-time continuum that I know and love. Yeah.

110.647 - 126.04 Tom Bilyeu

So I'm wondering, okay, if I for a second say you have touched on something that's really important, which is that space-time is the simulation.

Chapter 2: How does Donald Hoffman explain the concept of consciousness?

126.02 - 149.833 Tom Bilyeu

But I don't need to draw the conclusion that consciousness is the fundamental thing. That just becomes a debate about whether consciousness can emerge or not. It could be that there, and this feels more right to me when I try to imagine it, but I fully admit what I'm about to say simply pushes God farther down. It kicks the can. Okay.

0

149.813 - 176.25 Tom Bilyeu

So what feels intuitive to me because it's what I'm doing is that I exist in somebody else's simulation that exists in the real world. And that person, they still need God or something. I have not in any way, shape or form explained that I've kicked the can. But then all the sort of There's a set of rules. They seem like they're a little too perfect. They're a little too finely tuned.

0

176.27 - 194.67 Tom Bilyeu

You've got the Fermi paradox, which I'll probably ask you about later. Like all these things are like, nah, this is a little sus. The way that this whole space time is trying to hang together just doesn't really quite complete the circle, including the... So much of the energy that makes the universe work is this dark stuff. Don't worry about that.

0

195.071 - 209.303 Tom Bilyeu

Feels like a 13 year old programmer hand waving it away, telling the teacher like, ah, I just needed something in order to, you know, make all of this work. And when I do that, everything also falls into place. where I'm like, oh, wow, okay.

0

209.323 - 221.895 Tom Bilyeu

So I get how they're rendering all this in real time using the same principles that I'm now seeing AI use, pulling things out of the possibility space, because as somebody developing a video game, I will just tell you, the hardest thing is creating the art assets.

222.216 - 241.176 Tom Bilyeu

So they need something that can render this stuff on the fly and creating the art assets that look good, but are also optimized for the rendering engine because the rendering engine just gobbles resources. So it's like, When I take that view and instead of going, there's this magical thing called consciousness, I'm like, oh, I'm still dealing with God.

241.196 - 260.82 Tom Bilyeu

There's a God somewhere doing something, whatever. There's a thing I don't understand. But space-time being born of a 13-year-old just trying to, like, you could literally go to the Unreal Engine store and be like, give me Einstein's physics. Right. And you plunk them in and it would work. He wouldn't even have to know how to program it. Right.

260.8 - 281.256 Tom Bilyeu

He just took it, you know, whatever, give me what they understood in 2023 and we'll see what happens. Like that still works. So what is it that gives you the confidence that the thing that is giving birth to all of this is consciousness itself?

281.658 - 301.171 Donald Hoffman

Oh, I'm not confident at all. Is it your leading theory? It's just my leading theory. Why is it your leading theory? First, I would agree with you that we could just say that there are some kind of dynamical entities outside of space-time and be agnostic about the nature of those entities, just write down their dynamics and then show how it projects into space-time, and we could be good.

Chapter 3: What evidence does Hoffman provide for the simulation hypothesis?

388.112 - 392.398 Donald Hoffman

So neurons couldn't create consciousness because they're not even there to do it. And nor could particles.

0

393.339 - 411.981 Tom Bilyeu

Particles don't exist when they're not perceived. Here's where limited minds like mine get tripped up. Because your analogy is so profound and feels so right, and for this to be a simulation, I say to myself, something has to be running the simulation. And I can't get myself outside of that something somewhere is going to be physical.

0
0

412.962 - 414.665 Tom Bilyeu

That's a hard one for me too.

0

415.366 - 434.116 Donald Hoffman

By the way, I have all the same knee-jerk emotional reactions that everybody else has to this stuff, even stronger. So maybe that's why it's good for someone like me to be doing this because my emotions don't believe any of this. They don't believe it at all. It's literally only the mathematics pushing me, kicking and screaming at each step.

434.596 - 460.568 Donald Hoffman

So you have to go with the mathematics and what the theories are saying. But I don't find it that intuitive. Maybe I will at some point, but I don't find it that intuitive. So, yeah, you could say, you know, we don't need to talk about consciousness. There's just some dynamical entities outside of space-time. Why can't consciousness be a part of the simulation? For all I know, it may be.

461.189 - 474.566 Donald Hoffman

So maybe this thing that I called awareness, where this prior to any particular conscious experiences, now there I'm completely in over my head. I have no idea what to say about that thing. I literally have nothing intelligent to say.

475.047 - 485.14 Tom Bilyeu

What if awareness is just the qualia of being rendered, of your process being run by the central computer?

487.837 - 512.427 Donald Hoffman

That's as good an idea as I've ever had, but I don't feel very confident in this area at all. I mean, the closest we can personally get is the kind of thing I suggested, you know, go into a quiet room, turn off the light, let go of thought, which is not easy, let go of everything and try to just be aware of awareness. Be aware of being aware and try to sit there with that.

Chapter 4: How does the idea of space-time relate to consciousness?

542.096 - 555.881 Donald Hoffman

Our current models are, but we haven't proven that. Does local realism not being real mean that it has to be computational? No, it doesn't entail. I mean, so it doesn't entail that at all. No.

0
0

555.961 - 587.558 Tom Bilyeu

Now I'm broken again. I don't know how to make sense of that. Right, so how can anything, how, this is interesting. Here's my base where I realize I don't know how to escape this. I feel like for qualia to exist, it must be processed. I will even grant that the processing is simply the Markovian dynamics of moving from one thing to another, the switching of states, fine.

0

588.239 - 592.826 Tom Bilyeu

But it is moving from one state to another, which I will call that processing.

0

593.367 - 600.717 Donald Hoffman

Right. It's just not a physical process. And it doesn't have to be a computational process even. It could be functions that are not computational.

600.983 - 605.231 Tom Bilyeu

Yeah, I try not to kill the audience with the things I just can't remember.

605.251 - 611.262 Donald Hoffman

Well, it hurts me too. I'm telling you these things, but not because it's easy for me. My head hurts too thinking about these things.

611.342 - 615.29 Tom Bilyeu

Do you have an example of something that's non-computational? I think you gave one earlier, but I forget.

616.031 - 640.508 Donald Hoffman

Well, so the standard story that you'd – if you take a computer science class and – study of the theory of computation, they'll tell you about something called the halting problem. This is one of the big problems. Turing, I believe, posed it and showed that it was not computational. The question is this. A universal Turing machine is like a universal computer. You can give it a program.

Chapter 5: What are the implications of consciousness being fundamental?

1146.62 - 1164.819 Tom Bilyeu

That fine, but going back to neurons, if I smash somebody's head a million years ago, maybe that's too far, because the brain's changed, 100,000 years ago, neurons would look the same, even though I don't know what they are. I'm just like, meh, when you smash a head, this is what you see. If I smash that same head today, I'm gonna see the same thing.

0

1165.319 - 1170.805 Tom Bilyeu

Because even if this is all a simulation, there is a level of persistence.

0

1170.785 - 1188.152 Donald Hoffman

And I completely agree with you on that. I was just raising the question, could we come up with a game that was so simple, that was so trivial, that in some sense, persistence was irrelevant. I mean, you either are told bad or good. That's all you're told, bad or good, and you do something random.

0

1188.132 - 1212.162 Tom Bilyeu

When temperatures drop, your wardrobe either works or it doesn't. Premium materials aren't just about luxury. They're functional requirements. Mongolian cashmere, Italian leather, wool coats that actually keep you warm. That's performance gear. I ordered a Mongolian cashmere sweater from Quince as a gift last month. When it arrived, I was very impressed.

0

1212.562 - 1237.357 Tom Bilyeu

Super soft, high quality, exactly what you'd expect from luxury cashmere, except it was $50 instead of $400. Quince cuts out the middlemen and traditional markups. No department stores, no luxury retail overhead, same factories producing for high-end brands. Same materials, same rigorous standards for craftsmanship and ethical production. They just deliver it direct.

1237.838 - 1263.075 Tom Bilyeu

Their winter lineup has everything you need. Mongolian cashmere sweaters, wool coats, down jackets, Italian leather, and suede outerwear built to hold up season after season. Classic styles that don't fall apart after one winter. plus free shipping on every order, 365-day returns and zero risk. Refresh your winter wardrobe with Quince.

1263.436 - 1281.96 Tom Bilyeu

Go to quince.com slash impactpod for free shipping on your order plus that 365-day return policy. Now available in Canada too. That's quince, Q-U-I-N-C-E dot com slash impactpod.

1281.94 - 1308.066 Tom Bilyeu

pod free shipping and 365 day returns quince.com slash impact pod that's that's what i'm saying the cool you're talking now about behavior okay which right so if if we're in agreement on persistence i agree on the persistence that the um just to say it another way the simulation is a set of rules descriptions assets like art assets for just an easy way to explain it

1308.046 - 1326.409 Tom Bilyeu

And so there's going to be uniformity across everything that uses a headset. They're all going to be the same. So I don't have to like create all these individual things. I agree. Yeah. Then you have a very separate notion, which is the behaviors. We were talking about this earlier. This still really, I don't know how to understand it.

Chapter 6: How do near-death experiences relate to consciousness?

2189.09 - 2209.716 Donald Hoffman

And so I'm proposing that there are these conscious experiences that give rise to space-time as an interface. And when I write down the most simple mathematical model that I can do for that, all of a sudden that mathematics, I wasn't intending it, but the mathematics points to a single major consciousness that I can never describe.

0

2210.697 - 2217.325 Donald Hoffman

So that's the sense in which I say it was sort of pointed to that. And I would guess that

0

2218.739 - 2248.138 Donald Hoffman

Other conscious agents with either interfaces that are not even like our space-time interface but have mathematical skills and are coming up against the limits of their own interface and starting to realize, oh, I thought this was real but this is just the interface, might, under the hypothesis that consciousness is fundamental, might run into the same thing and then get pointed by their own mathematics to a universal consciousness.

0

2248.287 - 2265.979 Donald Hoffman

But again, these are deep waters, and I'm not secure here at all. But I would say that the free will—I mean, I have good discussions like with Annika Harris and so forth about free will. And free will is a standardly understood— Probably not.

0

2266.099 - 2283.525 Donald Hoffman

But free will in this new sense in which I'm saying that there could be a scale-free notion and a new mathematical model of free will that's scale-free, quite possibly there. And to your point about it's not dictated. There's exploration, real exploration going on.

2283.505 - 2299.8 Donald Hoffman

I would, again, agree that there's real, to the extent that I'm talking about all these little agents having their genuine free will, there's genuine, real exploration going on, even though it's not contradiction to say as well that the one has the free will.

2301.021 - 2313.512 Donald Hoffman

See, in other words, in some cases, when we think about things, we think it has to be this or that, but when we look at it more closely, we realize that there's a deeper way of thinking about it in which both can be true, and we hadn't thought about it that way.

2313.492 - 2327.809 Tom Bilyeu

Okay, so if those are deep waters, I'm going to drag you to the bottom of the Marianas Trench on this one. Does consciousness have a form?

2333.536 - 2340.664 Donald Hoffman

I would say awareness has no form, but assumes all sorts of conscious forms.

Chapter 7: What are the mathematical models proposed in Hoffman's paper?

2757.872 - 2761.517 Donald Hoffman

I hope we're using language the same way.

0

2761.857 - 2776.537 Tom Bilyeu

Probably not, but you're much more comfortable with that things are not physical even outside of space time. I see it as it's a maybe different set of rules or something, but that it's still physical. But I accept that. Well, there are rules.

0

2777.578 - 2801.291 Donald Hoffman

So there are going to be rules. Maybe physical, I mean made out of matter inside space and time. That's what I mean by physical. Something that's made out of particles in space and time. By hypothesis, the conscious agents are not inside space and time at all. So they're not physical in that sense. They are rule governed and I can say that they exist even if I don't perceive them.

0

2801.851 - 2825.854 Donald Hoffman

I could say that they exist. Whereas stuff in the headset is only there when I render it. So maybe we're not disagreeing. And I'm not saying it's necessary that when you use your headset to look at the agents that create the headset that you will necessarily see neurons. I'm saying that we could easily set up a situation or with some effort, we could set up a situation in which that was the case.

0

2827.184 - 2850.471 Donald Hoffman

In other cases, you might see only a single neuron, for example, if you're a very simple thing or some other structure. It depends on the nature of your interface. But for an interface like ours, so another way to put it is here's what I think neurons are. Neurons are our interface looking at the conscious agents that are constructing our interface. That's what neurons are.

2850.531 - 2861.945 Donald Hoffman

They're the interface symbols, headset symbols that our headset gets when it looks at the conscious agents that are constructing the headset. That's what it says.

2861.965 - 2893.783 Tom Bilyeu

Okay. So I asked a variant of this question earlier, but I don't think we ever got to the answer. So as we make all these breakthroughs, would you stay inside the headset if you... If you could, there were two paths before you. Path number one is you completely exit the headset and inside the game world, the simulation, your avatar falls over and basically appears dead.

2894.925 - 2907.673 Tom Bilyeu

But you are now like out chilling with the consciousness or you return to the consciousness as maybe you become aware of your oneness with the consciousness and that feels like the right way to sum up the way you see it. Yes.

2907.874 - 2936.472 Donald Hoffman

Yeah. I think that that idea is, is, um, can't be dismissed out of hand. I think it's a very interesting idea and I don't have a better one right now. So, so yes, it, the, it feels to me like, um, I'm not my body. My body is just an avatar. If you're in virtual reality – You do feel that. Well, I think that. I'll say that. I'm very much attached to my body.

Chapter 8: How does Hoffman envision the future of consciousness studies?

4063.497 - 4084.616 Donald Hoffman

If I run out of time before I get my next meal, if it takes too much time to get my next meal, it's over. If it takes too much time to get my next drink of water, it's over for me. Time is my most fundamental limited resource. So that limited resource of time is not an insight into reality. That's an artifact of projection from a timeless conscious agent dynamics.

0

4085.016 - 4106.039 Donald Hoffman

And that also suggests all the other limited resources, that's all artifacts. So evolution with natural selection is a beautiful theory. But it's the theory of all the artifacts that you see when you do a projection from a realm in which there are no limited resources, there is no competition. But it looks like evolution by natural selection in this projection.

0

4106.079 - 4125.099 Donald Hoffman

It looks like there's an arrow of time. So all of our intuitions right now about learning new stuff, it's going to be very hard for us because our intuitions are deeply shaped right now by our interface where there's an entropy arrow. And in this realm beyond, there need not be an entropy arrow.

0

4125.86 - 4147.909 Donald Hoffman

And so wrapping our heads around what it's like to have the notion of exploration where there's no entropy arrow. Now, I'm not saying I wrap my head around it, but I do know that the mathematics is there, that the Markovian dynamics does not have to have an arrow of time in the sense of an arrow of increasing entropy.

0

4148.615 - 4173.373 Donald Hoffman

So, and that's, again, one of the points of doing science with precise mathematics. I get emails quite often from people that I think are very, very bright and have really good ideas. And they don't know how to take them and make them precise. And as a result, you can never surprise yourself.

4174.771 - 4196.762 Donald Hoffman

You can never – like Einstein, when he had his idea about – you mentioned the falling elevator and so forth. And so he had that in 1907 or something like that, 1906. And it wasn't – he worked for years to take that idea and make it mathematically precise, 1915. And he learned tons and tons of what at the time was state-of-the-art, fairly new math.

4198.227 - 4231.642 Donald Hoffman

It was hard for him, sleepless nights, pulling his hair out, really working hard to take his good intuition. So he finally wrote down in mathematics in 1915. And a year later, a guy named Schwarzschild wrote back to Einstein and said, here's a solution to your equations. And they predict what we now call black holes. Now, Einstein didn't. Foresee that? He didn't like it. He didn't believe it.

4232.285 - 4240.654 Donald Hoffman

He disbelieved in black holes. He wanted to get rid of them. So Einstein's theory came back and surprised him.

4241.866 - 4259.301 Donald Hoffman

And that's why it's so important for us to do science, because what we do is we take our best ideas that we have right now, and then we make them mathematically precise, and then the mathematics comes back and it slaps us in the face and says, here are the implications of the ideas that you started with.
