What do we live in: the only uniÂverse that exists, or an elabÂoÂrate comÂputÂer simÂuÂlaÂtion of a uniÂverse? The quesÂtion would have fasÂciÂnatÂed Isaac AsiÂmov, and that preÂsumÂably counts as one of the reaÂsons the Isaac AsiÂmov MemoÂrÂiÂal Debate took it as its subÂject last year. Though the so-called “simÂuÂlaÂtion hypothÂeÂsis” has, in varÂiÂous forms, crossed the minds of thinkers for milÂlenÂnia, it’s enjoyed a parÂticÂuÂlar moment in the zeitÂgeist in recent years, not least because Elon Musk has pubÂlicly statÂed his view that, in all probÂaÂbilÂiÂty, we do indeed live in a simÂuÂlaÂtion. And, if you can’t trust the guy who hit it big with TesÂla and PayÂPal on the nature of realÂiÂty, who can you?
Well, you might also conÂsidÂer lisÂtenÂing to the perÂspecÂtives of New York UniÂverÂsiÂty philosoÂpher David Chalmers, MIT cosÂmolÂoÂgist Max Tegmark, and three theÂoÂretÂiÂcal physiÂcists, James Gates of the UniÂverÂsiÂty of MaryÂland, Lisa RanÂdall of HarÂvard, and Zohreh DavouÂdi of MIT.
They, with modÂerÂaÂtion by Neil DeGrasse Tyson, dig into the simÂuÂlaÂtion hypothÂeÂsis for two hours, approachÂing from all difÂferÂent angles its oriÂgin, its plauÂsiÂbilÂiÂty, and its impliÂcaÂtions. DavouÂdi, who has done seriÂous research on the quesÂtion, brings her work to bear; RanÂdall, who finds litÂtle reaÂson to credÂit the notion that we live in a simÂuÂlaÂtion in the first place, has more of an interÂest in why othÂers find it so comÂpelling all of a sudÂden.
Whether you believe it, reject it, or simÂply enjoy enterÂtainÂing the idea, you can’t help but feel a strong reacÂtion of one kind or anothÂer to the simÂuÂlaÂtion hypothÂeÂsis, and Tyson conÂtributes his usuÂal humor to knock the disÂcusÂsion back down to Earth whenÂevÂer it threatÂens to become too abstract. But how should we respond to the posÂsiÂbilÂiÂty of livÂing in comÂputÂed realÂiÂty in the here and now (or “here” and now,” if you preÂfer)? The Matrix proÂposed a kind of simÂuÂlaÂtion-hypothÂeÂsis world whose heroes break out, but we may ultiÂmateÂly have no more abilÂiÂty to see the hardÂware runÂning our world than Mario can see the hardÂware runÂning his. “If you’re not sure whether you’re actuÂalÂly simÂuÂlatÂed or not,” says Tegmark, “my advice to you is to go out there and live realÂly interÂestÂing lives and do unexÂpectÂed things so the simÂuÂlaÂtors don’t get bored and shut you down.” In these unreÂal times, you could cerÂtainÂly do worse.
