Ars Technica: No, physicists didn’t make a real wormhole. What they did was still pretty cool
"It’s not the real thing; it’s not even close to the real thing; it’s barely even a simulation of something-not-close-to-the-real-thing," physicist Matt Strassler wrote on his blog. "Could this method lead to a simulation of a real wormhole someday? Maybe in the distant future. Could it lead to making a real wormhole? Never. Don’t get me wrong. What they did is pretty cool! But the hype in the press? Wildly, spectacularly overblown."
