- Physicists propose that reality is not reproducible by algorithms, questioning the simulated universe hypothesis.
- The work combines quantum gravity and logical theorems such as Gödel's incompleteness theorem.
- The authors argue that there are aspects of reality that cannot be computed by any machine.
- The debate is gaining traction in Europe and Spain, with calls for review and additional testing.
For years, the hypothesis that we live inside a simulation It has been discussed in discussions, forums, and laboratories. Now, a paper authored by several physicists introduces a mathematical element that, according to its authors, It leaves the idea of a "simulated universe" without a computational basis..
The team, led by Mir Faizal (UBC Okanagan) and with the collaboration of Lawrence M. Krauss, Arshid Shabir, and Francesco Marino, published its findings in the Journal of Holography Applications in Physics and in academic repositories. Their central thesis is that The foundations of reality imply a non-algorithmic understanding, outside the scope of any program.
What exactly does the new work support?
The proposal links theoretical physics and mathematical logic: using the Gödel's incompleteness theoremThe researchers argue that in every formal system There are always truths that cannot be proven from within.. Transferred to cosmologyThis implies that a purely computational theory would never encompass all of reality.
Faizal succinctly summarizes the idea: A comprehensive description of the physical world using a computational theory of quantum gravity isAccording to their calculations, unfeasible in principleIn other words, there would not be a lack of computing power, but rather an insurmountable logical limit.
The key lies in the very concept of simulation: all simulation depends on rules and algorithmsthat process inputs to generate outputs. If they exist true facts inaccessible to any algorithmic procedure, no computer can exhaust realityhowever refined its architecture may be.
Implications for the “simulation universe” hypothesis
Co-author Lawrence M. Krauss puts it directly: if the fundamental laws give rise to space-time itself, they cannot be confined by himThis reading challenges the expectation of a “theory of everything” expressed in executable code.
The study also addresses the classic objection of recursion (simulations within simulations). Adding layers wouldn't solve the problem, they say, because a chain of algorithmic machines It would still be unable to generate that which, logically, is not computable.
According to the authors, the debate thus moves from the purely speculative realm to a more formal one: that of the verifiable mathematical toolsHowever, they admit that it will have to be discussed whether the scope of the theorems used covers all imaginable variants of “computation”.
In the European academic environment, The proposal has sparked both interest and caution.Several groups consulted point out that, although the reasoning is suggestive, It is advisable to review assumptions and definitions (what computation do we accept, what does “non-algorithmic” mean in physics) before declaring it final.
In Spain, the discussion has circulated through seminars and scientific networks, where the need to independent replication and to examine the logical-formal support with a magnifying glassIn parallel, the media echo rekindles classic questions about the nature of consciousness and the limits of artificial intelligence.
What remains to be verified
The technical crux lies in the extrapolation: The existence of unprovable truths in formal systems does not automatically imply that every physical description runs into a similar limit.The article proposes this leap with detailed arguments, but the community will ask for validations and nuances.
In any case, the debate has shifted. It's no longer just about guessing whether "we are a code," but about to pinpoint where the limits of computing lie applied to realityAnd that, in theoretical physics, That's a lot of ground gained..
The work as a whole, its citations, and the subsequent discussion all leave one key idea: If the foundation of the cosmos requires a form of understanding that cannot be contained in algorithms, then the dream of reproducing it entirely as software is futile. It doesn't hold up under the current rules.; the universe, at least according to this proposal, would not be a program, but something more elusive for any machine.
