A natural consequence of this is that the Universe can’t be a simulation<\/a>, since any such simulations<\/a> would have to operate algorithmically.<\/p>\n Related: <\/b>Slime Mold Has Been Used to Recreate The Invisible Web Holding Our Universe Together<\/b><\/a><\/p>\n “We have demonstrated that it is impossible to describe all aspects of physical reality using a computational theory of quantum gravity,” Faizal says<\/a>.<\/p>\n “Therefore, no physically complete and consistent theory of everything can be derived from computation alone. Rather, it requires a non-algorithmic understanding, which is more fundamental than the computational laws of quantum gravity and therefore more fundamental than spacetime itself.”<\/p>\n One of the most pernicious thorns in our understanding of how everything works is the insoluble relationship between the seamless fabric of spacetime and the fuzzy duality of quantum mechanics. We know that the Universe does function, but the mathematics used to describe each realm collapses when applied to the other.<\/p>\n Physicists have long sought a mathematical solution \u2013 a so-called quantum gravity<\/a>, or Theory of Everything<\/a> \u2013 that would allow physics to smoothly transition between general relativity<\/a> and quantum theory.<\/p>\n Faizal and his colleagues highlighted popular attempts to resolve problems with this transition, like string theory<\/a> and loop quantum gravity<\/a>.<\/p>\n These propose spacetime and quantum fields emerge from a foundation of pure information, beyond which nothing exists \u2013 described succinctly by American theoretical physicist John Wheeler<\/a> as getting an “it from a bit<\/a>“.<\/p>\n Yet there are good reasons, the team says, that “its” can’t come from “bits”.<\/p>\n YouTube Thumbnail<\/p>\n “Drawing on mathematical theorems related to incompleteness and indefinability, we demonstrate that a fully consistent and complete description of reality cannot be achieved through computation alone,” Faizal explains<\/a>.<\/p>\n “It requires non-algorithmic understanding, which by definition is beyond algorithmic computation and therefore cannot be simulated. Hence, this Universe cannot be a simulation.”<\/p>\n Arguing that the information from which reality emerges would need to be both fundamental and finite, the physicists turned to mathematicians Kurt G\u00f6del<\/a>, Alfred Tarski<\/a>, and Gregory Chaitin<\/a> to interrogate their hypothesis.<\/p>\n These three theoreticians \u2013 the latter two operating in the first half of the 20th century, and Chaitin from the 1960s \u2013 independently showed that there are hard limits to our ability to understand the Universe.<\/p>\n G\u00f6del’s famous 1931 incompleteness theorems<\/a> showed that any consistent mathematical system will contain true statements that nevertheless cannot be proven using its own rules. Tarski’s 1933 undefinability theorem<\/a> showed that an arithmetical system cannot define its own truth.<\/p>\n Finally, Chaitin’s incompleteness theorem<\/a> \u2013 which is similar to G\u00f6del’s work \u2013 shows that there’s a hard upper limit to how much complexity a formal algorithmic system can describe.<\/p>\n Using these logical theorems, the researchers find that physics itself cannot be fully computable. They propose that the only way to resolve a Theory of Everything is to add a non-algorithmic layer above the algorithmic one to create a Meta Theory of Everything, or MToE.<\/p>\n Win a $10,000 Space Coast Adventure Holiday<\/p>\n This meta-layer would be able to determine what’s true from outside the mathematical system, giving scientists a way to investigate phenomena such as the black hole information paradox<\/a> without violating mathematical rules.<\/p>\n And, of course, it puts to bed that pesky problem of whether we’re actually “real”.<\/p>\n “Any simulation is inherently algorithmic \u2013 it must follow programmed rules,” Faizal says<\/a>. “But since the fundamental level of reality is based on non-algorithmic understanding, the universe cannot be, and could never be, a simulation.”<\/p>\n![\"YouTube](\"https:\/\/www.europesays.com\/us\/wp-content\/uploads\/2025\/11\/27ed9af2a5c85d7212fc12b8e54c0e5e.jpeg\"\/)
