Recent physics experiments suggest the universe isn't "locally real," behaving like a simulation that only renders what is being observed. A tree falling on Mars may not actually fall until it's measured, similar to how an unseen area in a video game doesn't render.

In a reality where spacetime is not fundamental, physical objects like neurons are merely "rendered" upon observation. Therefore, neurons cannot be the fundamental creator of consciousness because they don't exist independently until an observer interacts with them.
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.
For a simulated reality to be coherent for multiple observers, it must have "persistence"—objects and laws that remain consistent. The moon appears the same to everyone who looks, ensuring a stable, shared experience, much like assets in a multiplayer game.
The persistence of objects and shared experiences doesn't prove an objective reality exists. Instead, it suggests a deeper system, analogous to a game server in a multiplayer game, coordinates what each individual observer renders in their personal perceptual "headset," creating a coherent, shared world.
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.
If any civilization can create a convincing simulation, and those simulations can create their own simulations, the number of simulated realities would vastly outnumber the single "base reality." This makes it statistically probable that we are living inside one of the countless nested simulations rather than the original one.
The reason we don't see aliens (the Fermi Paradox) is not because they are distant, but because our spacetime interface is designed to filter out the overwhelming reality of other conscious agents. The "headset" hides most of reality to make it manageable, meaning the search for physical extraterrestrial life is fundamentally limited.
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.
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.
Hoffman's model proposes that consciousness is not a product of the physical brain within space-time. Instead, consciousness is the fundamental building block of all existence, and space-time itself is an emergent phenomenon—a "headset" or user interface—that is created by and within consciousness.
