Experiments testing quantum theory have conclusively proven that "local realism" is false. This means physical objects, like electrons, do not possess definite properties such as a specific position or spin until the moment they are actually measured or observed, challenging our classical intuition about reality.

Hoffman's theory posits that our perceived world is not a persistent, objective reality but a simulation that is rendered only when an observer looks at it. According to this model, when you look away from an object, it ceases to exist and is only re-rendered upon observation.
John Martinis's 1985 experiment demonstrating quantum mechanics at a macro scale was noteworthy but not seen as a Nobel-worthy breakthrough at the time. Its significance grew over decades as it became the foundation for the burgeoning field of quantum computing, showing the long-tail impact of foundational research.
Pure, curiosity-driven research into quantum physics over a century ago, with no immediate application in sight, became the foundation for today's multi-billion dollar industries like lasers, computer chips, and medical imaging. This shows the immense, unpredictable ROI of basic science.
After proving quantum mechanics at a macro scale, John Martinis was inspired by a Richard Feynman talk on quantum computation. Feynman's vision for a practical application provided the motivation for Martinis to dedicate his career to building a quantum computer, transforming an abstract discovery into a world-changing goal.
The entire field of quantum computing was sparked by physicist Anthony Leggett's provocative question: "Do macroscopic objects behave quantum mechanically?" This question directly inspired John Martinis's Nobel-winning experiment, which proved it was possible and laid the groundwork for the field.
Reductionism—understanding things by breaking them into smaller parts—has been successful because we were only studying our "headset." However, this approach hits a hard limit. Physics shows that at the smallest scales (Planck length), the concept of "smaller" ceases to make sense. Spacetime dissolves, meaning the foundation of reductionism is an illusion.
Physicists are finding structures beyond spacetime (e.g., amplituhedra) defined by permutations. Hoffman's theory posits these structures are the statistical, long-term behavior of a vast network of conscious agents. Physics and consciousness research are unknowingly meeting in the middle, describing the same underlying reality from opposite directions.
Science's incredible breakthroughs have been about understanding the rules of our virtual reality (spacetime). Being a "wizard" at the Grand Theft Auto game (mastering physics) doesn't mean you understand the underlying circuits and software (objective reality). The next scientific frontier is to use these tools to venture outside the headset.
Cognitive scientist Donald Hoffman argues that spacetime and physical objects are a "headset" or VR game, like Grand Theft Auto. This interface evolved to help us survive by hiding overwhelming complexity, not to show us objective truth. Our scientific theories have only studied this interface, not reality itself.
Physicist Anthony Leggett argued that the Schrödinger's Cat paradox only exists if one assumes a macroscopic object can be in a quantum superposition. He pointed out there was no experimental evidence for this, reframing the famous paradox as a testable scientific question that spurred real-world research.
