It’s a plot device beloved by science fiction: our entire universe might be a simulation running on some advanced civilization’s supercomputer. But new research from UBC Okanagan has mathematically proven this isn’t just unlikely—it’s impossible.
Dr. Mir Faizal, Adjunct Professor with UBC Okanagan’s Irving K. Barber Faculty of Science, and his international colleagues, Drs. Lawrence M. Krauss, Arshid Shabir and Francesco Marino have shown that the fundamental nature of reality operates in a way that no computer could ever simulate.
Their findings, published in the Journal of Holography Applications in Physics, go beyond simply suggesting that we’re not living in a simulated world like The Matrix. They prove something far more profound: the universe is built on a type of understanding that exists beyond the reach of any algorithm.
“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.”


Like others have stated, this would only hold true if the supposed outer universe to ours has the same properties as ours. So while it may be true that we will never simulate a universe that is equal to ours (with classical computers and algorithms), it doesn’t negate that a computer/device in a universe could simulate an inferior version of the universe.
Take Minecraft as an example. You can make the logic leap and say it’s a simulated universe, and people have in Minecraft created am inferior version of Minecraft with Redstone logic.
So of you can create an inferior version of Minecraft within Minecraft, it’s not much of a jump to think that we could be an inferior version of some outer universe.
