Podcast: Mayim Bialik's Breakdown
Episode: How Consciousness Creates Our Reality. Why Science & Spirituality Can’t Explain Reality and the Scientific Breakthrough That Could Change Life As We Know it.
Release Date: November 4, 2025
Host: Mayim Bialik
Guests: Dr. Donald Hoffman (Cognitive Scientist), Jonathan Cohen (Producer/Co-Host)
Overview
This episode delves into profound questions at the intersection of science and spirituality: Is our experience of reality an illusion? Is consciousness fundamental to everything, and if so, how do tools from science, math, and spirituality converge to answer the biggest mysteries of existence?
Dr. Donald Hoffman, a leading cognitive scientist, discusses his provocative view that space and time are not fundamental realities, but rather a kind of “VR headset” for consciousness. The conversation unpacks why both physics and spiritual traditions point to something “beyond spacetime,” why neither camp alone has the full answer, and the potential for a mathematical breakthrough to revolutionize what we think is possible—from consciousness, to healing, to technology itself.
Key Discussion Points & Insights
1. The “Space-Time VR Headset” & Consciousness as Primary Reality
- Dr. Hoffman asserts: What we perceive—objects, bodies, space, and even time—is constructed by consciousness; it’s not the bedrock reality.
- Quote: "Everything you see inside of space time is your construction. From the consciousness point of view. Spacetime isn't fundamental. It's just a VR headset." (00:00)
- He explains that neuroscience provides clues about how this “headset” is generated, but deeper reality remains beyond sensory experience.
- Space and time, he argues, break down at the Planck scale, and even the best scientific theories (quantum theory, relativity) show their own limitations (07:36, 31:15).
2. Where Science and Spirituality Meet
- Jonathan Cohen crystallizes the dilemma: "Do I believe in science or do I believe in God? Is there a place where those two things literally meet?" (00:41)
- Dr. Hoffman’s view: Science has mathematical rigor but is now forced by physics to admit spacetime is incomplete; Spiritual traditions intuited that spacetime isn’t final, but lack explanatory models and experiments.
- Quote: “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... But they've not had any mathematical tools.” (09:23)
3. Metaphors for Reality: From Plato’s Cave to Modern VR
- Modern analogies, like video games and VR, best help us understand the illusion:
- Quote: “Think of it as a VR headset. Everything that you're seeing is a VR headset.” (21:35)
- Plato’s allegory of the cave is cited as a precursor; what we see are shadows, not the real objects (25:51, 26:04).
4. Personal and Emotional Impact
- Dr. Hoffman applies these concepts to daily experience and identity:
- Our sense of being “chained” to our body or to a linear timeline is itself constructed; we are “infinite consciousness looking through a very, very small headset.” (01:15, 28:21)
- Letting go of these “chains” is both an emotional and intellectual challenge, often requiring practices akin to deep meditation (28:21).
5. Limits and Power of Scientific Models
- Discussion of how science constructs models based on assumptions; Einstein and quantum theory both start with space and time as “miracles” or axioms, but show their own breakdown (31:15).
- Quote: “Every scientific theory starts with a miracle or some miracles. We call them our assumptions, but they're the miracles of the theory.” (34:20)
- Scientific progress, at its best, knows its limits and seeks to move beyond them.
6. Simulation Theory vs. Hoffman’s View
- Dr. Hoffman makes a clear distinction between his theory and standard simulation hypotheses:
- Simulation theories assume a “base level” reality that is itself within spacetime and that computers can create consciousness de novo—a claim he says lacks evidence.
- Quote: “My point of view is superficially like the simulation kind of theories, but it has very, very deep differences. Computers cannot create consciousness de novo from just the computational.” (37:49)
7. AI, Language Models, and Human Consciousness
- Dr. Hoffman acknowledges the usefulness of large language models (like ChatGPT), but insists these do not constitute intelligence or consciousness:
- Quote: “They don't understand what they're doing... they're very, very helpful. But I also know how to ask them questions that reveal that they're dumber than cucumbers.” (45:04)
- There is no mathematical or scientific model that explains how physical computation gives rise to a specific conscious experience (47:14).
- On linking brain activity to consciousness: Correlation does not imply causation, and all “neural correlates” studies do not actually solve the hard problem (51:33).
8. Substances and Spiritual Experience
- The show references psychedelic experiences as another (sometimes hand-waved) way to “remove the headset,” but Hoffman urges scientific rigor:
- Both scientists and spiritualists must provide testable, predictive theories if they want their ideas to be taken seriously in the modern age (55:37, 56:45).
9. Demands for a Unified Theory
- Dr. Hoffman advocates for a new mathematical theory—a “theory of consciousness” outside space and time, that can nonetheless give rise to all the successes of current physics (like relativity, quantum mechanics).
- Until spiritual or anomalous claims produce predictions or explanations of phenomena like Einstein’s equations, he insists, they remain “out of the game.” (58:50)
- He is optimistic that such a theory, once achieved, will be transformative both technologically and for our understanding of ourselves (62:26).
Notable Quotes & Memorable Moments
- Dr. Hoffman: "Ultimately, who are you? You are the infinite consciousness looking through a very, very small headset... But you are that infinite consciousness." (01:05)
- Jonathan Cohen: "I love when people accidentally prove God." (01:27)
- Dr. Hoffman: "We know exactly where [spacetime] ceases to make sense. It doesn't make sense at 10 to the -33 centimeters and 10 to the -43 seconds." (07:36)
- Jonathan Cohen: "[Plato’s allegory:] They are chained to the reality of the cave and all they see is their perception and their interpretation of shadows on the wall. However... people like you, Donald Hoffman, are saying we can release those chains and we can step outside of that cave now..." (26:19)
- Mayim Bialik: "What does it mean for someone in their everyday life to be chained to a false reality or to their perception?... What does that mean to me if I'm just going about my daily life?" (27:53)
- Dr. Hoffman: "None of it exists apart from your experiences... To the extent that you're identified with your body... this is a very, very deep psychological and emotional kind of attachment." (28:21)
- Dr. Hoffman: "If you're assuming that the fundamental simulation is at the base level in a space time, then you're violating what the physicists are telling us... I wanted to make a clean distinction between what I'm saying and the simulation theory." (39:28)
- Dr. Hoffman: "If you think conscious experiences arise from physical systems like computers? Give me one theory that science has done, like the taste of mint or the smell of garlic. Give me one. Until you have one on the board, there's nothing to take." (47:14)
- Dr. Hoffman: "I'll put it this way... If you want people to take you seriously in this age, you need to do something to show that this isn't... [just] hoaxes and mistakes and illusions from the spiritual side... I want a theory that gives me, for example, Einstein's special theory of relativity. I want the length contractions and time dilations..." (56:45)
- Dr. Hoffman: “If we get one [theory] that works, then those who said that they knew it couldn’t be done were flat wrong.” (62:25)

Takeaways
- Both scientific and spiritual traditions have glimpsed aspects of reality's true nature, but each is missing pieces the other offers.
- The next revolution in understanding—bringing about new technologies, forms of wellness, and insights into our true identity—may only come when we build a precise, mathematical, testable theory that unites consciousness, matter, and spacetime from the ground up.
- Dr. Hoffman’s work invites us to both humility (knowing the limits of our models) and awe (that something transcendent may be just beyond the “headset”), while insisting on the tough rigor of science.
This summary captures the core of this deeply philosophical and scientifically grounded conversation, offering newcomers a set of conceptual handles and memorable moments to understand and discuss how consciousness might fundamentally create our reality.
