The idea of alternate universes is mainstream, at least among laypersons. Some people even believe they may have experienced another world. From glitch in the matrix stories, to bizarre urban legends and the so-called “Mandela Effect,” there is enough anecdotal evidence that other universes exist that we can’t just dismiss the idea. One scientifically-backed idea supports what many have long suspected: that black holes do not culminate in a crushing singularity, but rather they are “portals to other universes,” or perhaps Farscape-esque tunnels to distant parts of our own universe.
A compelling urban legend is the case of “The Man From Taured.” Take a look at the video:
Whether these stories are more than stories is up for debate. But scientists have introduced a new theory called Many Interacting Worlds, a spin-off of other quantum mechanics theories such as the Many Worlds theory. Professor Howard Wiseman, a physicist at Griffith University in Brisbane, Australia, and one of the creators of the new Many Interacting Worlds theory, had this to say:
“In the well-known ‘many worlds interpretation,’ each universe branches into a bunch of new universes each time a quantum measurement is made. All possibilities are therefore realized—in some universes the dinosaur-killing asteroid missed Earth. In others, Australia was colonised by the Portuguese. But critics question the reality of these other universes, since they do not influence our universe at all. [emphasis added] On this score, our ‘many interacting worlds’ approach is completely different, as the name implies.”
This new theory is exactly what it sounds like: many worlds interacting with and influencing each other in the quantum realm. It could even open up the possibility that human adventurers could visit other universes.
As of yet, there is no experimental evidence to support this exciting theory. But lack of evidence doesn’t mean Wiseman and his collaborators are wrong. As the above anecdotes show, we live in a wondrous and mysterious universe. The more we know, the more we realize we don’t know. As Nobel Prize winning physicist Richard Feynman once said, “I believe I can safely say that nobody understands quantum mechanics.” He could have easily said the same thing for our universe as a whole.
