Scientists finally conclude: Universe is not a giant computer simulation

A team of theoretical physicists argues that the laws of reality go beyond what any algorithm can compute, challenging the popular belief that the universe might be a simulation

For years, the idea that we might be living in a giant computer simulation, a cosmic video game run by some higher intelligence, has fascinated scientists, philosophers and sci-fi fans alike. But a new scientific paper now says that’s not just unlikely. It’s logically impossible.

 

In a bold new study, researchers have proposed what they call a “Meta-Theory of Everything” (MToE), a framework suggesting that the universe operates through laws and principles that no algorithm or computer could ever fully replicate.

 

The team’s argument challenges the dream of finding a single, all-encompassing “Theory of Everything” — the holy grail of modern physics that would unite Einstein’s relativity and quantum mechanics under one equation.

 

According to the study by a team of physicists, led by Mir Faizal of the University of British Columbia, both classical physics and quantum mechanics rely on algorithms — rule-based systems that calculate how particles and spacetime behave. But at the deepest level, say the researchers, the universe doesn’t follow strictly computable laws. Instead, it involves what they call non-algorithmic understanding — truths that no computer, no matter how advanced, can deduce.

 

The authors base their argument on mathematical results like Gödel’s incompleteness theorem and Turing’s halting problem, which show that some truths are fundamentally undecidable by any computational system. Applying these ideas to physics, they argue that nature itself must include non-computable elements — aspects of reality that cannot be simulated.

 

“Any simulation of the universe would itself be algorithmic,” the researchers write, “but the universe contains truths beyond algorithmic reach. Therefore, a simulation of the full universe is impossible.”

 

Their theory also reinterprets some of the most puzzling areas in physics — from black holes and the Big Bang to quantum gravity — as places where computation itself breaks down, but not science. In other words, the limits of calculation don’t mean the end of explanation.

 

“It has been suggested that the universe could be simulated. If such a simulation were possible, the simulated universe could itself give rise to life, which in turn might create its own simulation. This recursive possibility makes it seem highly unlikely that our universe is the original one, rather than a simulation nested within another simulation,” says Dr. Faizal. “This idea was once thought to lie beyond the reach of scientific inquiry. However, our recent research has demonstrated that it can, in fact, be scientifically addressed.”

 

The study suggests that this non-computational layer of reality could even relate to consciousness. If human reasoning can grasp certain truths that computers cannot, it may hint that our minds are tapping into that deeper, non-algorithmic structure of the universe.

 

While the idea may sound abstract, its implications are staggering. It means that no matter how powerful artificial intelligence becomes, there may always be aspects of the universe — and of human understanding — that remain beyond digital reach.

 

The research rests on a remarkable idea about the nature of reality itself. Modern physics has long outgrown Newton’s picture of solid objects moving through empty space. Einstein’s relativity reshaped that view, showing that space and time are woven together into a flexible fabric. Quantum mechanics then revolutionised our understanding once more, revealing a world ruled by probabilities rather than certainties.

 

Now, the frontier field of quantum gravity takes this even further — suggesting that space and time aren’t basic ingredients of the universe at all, but rather emerge from something deeper and more abstract: pure information.

 

As the authors put it: the universe isn’t made of “bits” or “its”, but something deeper — a reality that can’t be computed, only understood.
