Tom Campbell

An icebreaker

A physicist who once ran lab experiments on out-of-body states argues reality itself is a vast information-processing system. Physical law, he holds, emerges from rules a larger consciousness runs, the way a video game runs on code.

Worth knowing · 1 of 5
What is the core claim of his theory?
He holds that physical reality is a rendered output of a vast information-processing system run by what he calls a larger consciousness system. Space, time, and matter, in his account, are the interface, not the foundation.
Worth knowing · 2 of 5
What is his scientific background?
He trained in physics, completing doctoral research at the University of Virginia without taking the degree, then worked for decades as a physicist in government and industry. He draws on that training to argue his model can explain quantum results.
Worth knowing · 3 of 5
How does he say the theory can be tested?
He encourages people to run their own inner experiments, such as attempting out-of-body states, treating personal experience as data rather than proof of anything external. Mainstream physicists have not adopted this as a way of testing physical theory.
Worth knowing · 4 of 5
Where did his research into consciousness begin?
In the early 1970s he worked as a physicist in a private lab studying sound-based methods for inducing altered states, alongside its founder. He treats those early sessions as the origin of the theory he developed decades later.
Worth knowing · 5 of 5
How do mainstream physicists respond to his claims?
Most working physicists have not engaged his model directly, and critics who have call it a mix of real physics terms with untestable metaphysical claims. He maintains the model is falsifiable through its predictions about quantum experiments.
Words to know
Larger Consciousness SystemHis term for the encompassing digital intelligence he says generates physical reality.
Theory of Everything (TOE)A single framework meant to unify physics, consciousness, and metaphysics; the source of his trilogy's title.
Rendered realityHis description of physical experience as an interface generated moment to moment, not a fixed substance.
More words
Hemi-SyncAn audio method using a different tone in each ear, developed at the lab where he began his consciousness research.
FalsifiabilityA theory's requirement to make predictions that could, in principle, be proven wrong by evidence.

Tom Campbell · Physicist who developed the theory

He holds that physical reality is generated, moment to moment, by a vast digital system organized around consciousness rather than matter, laying out the claim across a self-published trilogy begun in 2003. He frames the model as testable, not a matter of belief.

Robert Monroe · Broadcasting executive he worked with early on

In the early 1970s he brought a young physicist into the lab he had built to study out-of-body states, where the two worked on sound-based methods for inducing altered states.

David Chalmers · Philosopher who examined simulated worlds

In a 2022 book he argued that a fully simulated world would still count as a genuine reality, not a lesser one, though he stopped well short of claiming this world has been shown to be one.

Sabine Hossenfelder · Physicist who has argued against consciousness-based physics claims

In Existential Physics (2022) she argued that treating consciousness as fundamental to physical law is unsupported by evidence though not strictly disprovable, and distinguished such ideas from claims that outright conflict with established physics.
