People have been discussing this idea for years, and it’s gained more traction as of late. Several articles in 2016 were sparked by billionaire Elon Musk’s comments at a technology conference. “There’s a billion to one chance we’re living in base reality,” he said, among other things.
As one might imagine, the “simulation” idea is a controversial topic. Some people take it very seriously — Tad Friend at The New Yorker wrote “Many people in Silicon Valley have become obsessed with the simulation hypothesis, the argument that what we experience as reality is in fact fabricated in a computer; two tech billionaires have gone so far as to secretly engage scientists to work on breaking us out of the simulation.”
Rich Terrile (a scientist at NASA’s Jet Propulsion Laboratory) said that if our universe is finite, it’s computable, and therefore could be a simulation. He adds: “Reasons to believe that the universe is a simulation include the fact that it behaves mathematically and is broken up into pieces (subatomic particles) like a pixelated video game.” This could, however, just be how the universe works. We don’t know.
Skeptics of the “simulation” theory point out that there isn’t any proof to support the idea. There are many arguments for and against it — so who is correct? Well, to be honest, that’s likely irrelevant. But it’s interesting to think about.
