If we were living in a computer simulation, would we be able to tell we were living in a computer simulation? It’s a question that’s difficult to answer, but physicist Melvin Vopson of the University of Portsmouth in the UK believes that he may have found a clue.

According to his latest study, gravity could be a product of computational processes within the Universe, a by-product of the Universe’s attempt to keep information and matter neatly organized in space and time.

“My findings in this study fit with the thought that the Universe might work like a giant computer, or our reality is a simulated construct,” Vopson says.
