"We are not living in computer simulation," researcher

ByBruce Aldridge

The fact that the real world in which humans live is actually only simulation is "Simulation hypotIn Tesla and SpaceXEarlon maskMr. and others also agree with this concept, but the paper on which the researcher claims is newly announced, "We are not living in computer simulation".

Simulation of the universeHuman beings simulate various events in various fields. And when humankind goes further and develops advanced civilization without perishing it, the possibility of being able to simulate the world itself of human beings is greatly thought. Furthermore, if there are creatures with sophisticated civilization than humans, it is possible to simulate the real world where human beings live, the world in which human beings actually live may be an event in the simulation, That is "simulation hypothesis".

New research results on the simulation hypothesis were presented by research teams by theoretical physicists at Oxford University in the UK. In the research, we conclude that the real world we live from "gravity anomalies" and "computational complexity" is not "just a simulation".

Zohar Ringel and Dmitry Kovrizhi who participated in the study said it is impossible to reproduce the specific quantum phenomena occurring in the metal by computer simulation. Initially,Quantum Monte Carlo methodUsingQuantum Hall effectI was doing research on. Quantum Monte Carlo is a quantum theoryMultiple body problemWe use a random sample to analyze the quantum Hall effect is a physical phenomenon caused by a strong magnetic field and very low temperature.

However, according to Mr. Ringel and Kovrizhi, it is clear that when we try to use the quantum Monte Carlo method for a unique phenomenon such as quantum Hall effect, we can not always perform well. This seems to be because the simulation becomes exponentially complicated as the number of particles sharply increases.

If the complexity of the simulation increases in proportion to the number of particles, if the number of particles doubles, the computer power required for the simulation will also be doubled. It is inevitable that this is an unrealizable simulation when computer powers must be added in the same way each time there are more particles to be simulated. Specifically, researchers calculate that simply storing information on hundreds of electrons requires physically more computer memory than the number of atoms in the universe.
