For some of us, the idea of parallel Universes spark our wildest dreams. If there are other Universes where certain events had different outcomes — where just one crucial decision went a different way — perhaps there could be some way to access them. Perhaps particles, fields, or even people could be transported from one to the other, enabling us to live in a Universe that’s better, in some ways, than our own. These ideas have a foothold in theoretical physics as well, from the myriad of possible outcomes from quantum mechanics as well as ideas of the multiverse. But do they have anything to do with observable, measurable reality? Recently, a claim has surfaced asserting that we’ve found evidence for parallel Universes, and Jordan Colby Cox wants to know what it means, asking:
There is an article floating around that claims that physicists in Antarctica have found evidence for a parallel universe. I find this highly unlikely, but I wanted to be sure by asking you to address the veracity of the story.
Let’s take a look and find out.
From a physics point of view, parallel Universes are one of those intriguing ideas that’s imaginative, compelling, but very difficult to test. They first arose in the context of quantum physics, which is notorious for having unpredictable outcomes even if you know everything possible about how you set up your system. If you take a single electron and shoot it through a double slit, you can only know the probabilities of where it will land; you cannot predict exactly where it will show up.
