Could we detect it if we live in a simulation?

“If quantum computing actually materializes, in the sense that it’s a large scale, reliable computing option for us, then we’re going to enter a completely different era of simulation,” Davoudi says. “I am starting to think about how to perform my simulations of strong interaction physics and atomic nuclei if I had a quantum computer that was viable.”

All of those elements have led Davoudi to take a position in regards to the simulation speculation. If our actuality is a simulation, then the simulator is probably going additionally discretizing spacetime to avoid wasting on computing assets (assuming, in fact, that it’s utilizing the identical mechanisms as our physicists for that simulation). Signatures of such discrete spacetime may doubtlessly be seen within the instructions high-energy cosmic rays arrive from: they might have a most popular course within the sky due to the breaking of so-called rotational symmetry.

Telescopes “haven’t observed any deviation from that rotational invariance yet,” Davoudi says. And even when such an impact have been to be seen, it could not represent unequivocal proof that we stay in a simulation. Base actuality itself may have comparable properties.

Here is further discussion from Anil Anathaswamy.  Via Robert Nelsen.  As you might already know, my view is that there is no such thing as a correct exterior perspective, and the idea of “living in a simulation” will not be clearly distinct from residing in a universe that follows some type of legal guidelines, whether or not pure and even theological.  The universe is concurrently the simulation and the simulator itself!  Anything “outside the universe doing the simulating” is then itself “the (mega-)universe that is simultaneously the simulation and the simulator itself.” and many others.
