Do gravitational anomalies prove we’re not living in a computer simulation?

Is our entire universe just a computer simulation? It sounds like the premise for a sci-fi movie, but over the years the idea has been debated by scientists in earnest. Now theoretical physicists believe they’ve found proof that our universe is far too complex to be captured in any simulation. Since we tend to use computers to run simulations with our current technology, those future humans would likely do the same, perhaps simulating their ancestors.

As a result, the amount of artificial universes would vastly outnumber the one “Real” universe, so statistically it’s far more likely that we live in one of these simulations.

Astrophysicist Neil deGrasse Tyson puts our odds of living in a simulation at 50/50, while Elon Musk is far less optimistic, saying the chance is “One in billions” that we inhabit the one true world.

Quantum Monte-Carlo simulations are used to model quantum systems, but the Oxford and Hebrew scientists found that quantum systems containing gravitational anomalies are far too complex to ever be simulated.

The quantities involved in the simulation will acquire a negative sign – essentially, there’s an infinite number of possibilities, so the simulation can’t possibly consider them all.

    not if you can use brains as a computer – it just may be far behond our current understanding of how things should work.
