If the universe is just a Matrix- like simulation, how could we ever know? Physicist Silas Beane of the University of Bonn, Germany, thinks he has the answer!. His paper “Constraints on the Universe as a Numerical Simulation” has been submitted to the journal Physical Review D !.

Are We Living in a Simulated Universe?

Remark: This person claimed that the whole world is a great simulation, and the whole world started with a simulated big bang. and every things are results of spontaneous program self-organization and automorphisms. The big bang happened in a kind of supercomputer And now we're inside of it. the Big Bang occurred approximately 13.75 billion years to our eyes, But perhaps within less than a second for simulator.

There exists substantial evidence that integers that appear in physics are emergent in character, see e.g. this essay by Prof David Tong

Because the integers are emergent, they're not fundamental and our world is fundamentally not the Matrix or anything analogous. Such abstract questions could have been inaccessible in the past but modern physics has actually turned them into a framework with predictions and these predictions seem to disagree with the observations, and the world is therefore not simulated or discrete at the fundamental level.

The existence of continuous symmetries – and continuous redundancies such as gauge symmetries – speaks against the conjecture that the world is fundamentally discrete. The verified postulates of quantum mechanics exclude the possibility that the world is fundamentally a "classical engine", too.
