Parallel Worlds Exist And Interact With Our World, Say Physicists

Quantum mechanics, though firmly tested, is so weird and anti-intuitive that famed physicist Richard Feynman once remarked, “I think I can safely say that nobody understands quantum mechanics.” Attempts to explain some of the bizarre consequences of quantum theory have led to some mind-bending ideas, such as the Copenhagen interpretation and the many-worlds interpretation.

Now there’s a new theory on the block, called the “many interacting worlds” hypothesis (MIW), and the idea is just as profound as it sounds. The theory suggests not only that parallel worlds exist, but that they interact with our world on the quantum level and are thus detectable. Though still speculative, the theory may help to finally explain some of the bizarre consequences inherent in quantum mechanics, reports

The theory is a spin-off of the many-worlds interpretation in quantum mechanics — an idea that posits that all possible alternative histories and futures are real, each representing an actual, though parallel, world. One problem with the many-worlds interpretation, however, has been that it is fundamentally untestable, since observations can only be made in our world. Happenings in these proposed “parallel” worlds can thus only be imagined.

MIW, however, says otherwise. It suggests that parallel worlds can interact on the quantum level, and in fact that they do.

“The idea of parallel universes in quantum mechanics has been around since 1957,” explained Howard Wiseman, a physicist at Griffith University in Brisbane, Australia, and one of the physicists to come up with MIW. “In the well-known ‘Many-Worlds Interpretation’, each universe branches into a bunch of new universes every time a quantum measurement is made. All possibilities are therefore realised – 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,” he added. “On this score, our “Many Interacting Worlds” approach is completely different, as its name implies.”

Wiseman and colleagues have proposed that there exists “a universal force of repulsion between ‘nearby’ (i.e. similar) worlds, which tends to make them more dissimilar.” Quantum effects can be explained by factoring in this force, they propose.

Whether or not the math holds true will be the ultimate test for this theory. Does it or does it not properly predict quantum effects mathematically? But the theory is certain to provide plenty of fodder for the imagination.

For instance, when asked about whether their theory might entail the possibility that humans could someday interact with other worlds, Wiseman said: 
“It’s not part of our theory. But the idea of [human] interactions with other universes is no longer pure fantasy.”

What might your life look like if you made different choices? Maybe one day you’ll be able to look into one of these alternative worlds and find out.


  1. If there are an infinite number of universes that cover all possible histories and futures certainly there would be a universe that scientists figured out how to travel or contact other worlds and would have done so to our world already. So, find the interdimensional traveler and you will have your proof. Haha

    1. The key to this is: to forget about dragging the bag of water around the objective universe. Mystics/yogis (researchers in consciousness) already know this is done in Consciousness. I am certain this is where highly detailed fiction comes from, other planes.

    2. Why do these hallucinating "physicists" obtain funding while those of us that do research on practical matters that can be experimentally tested, are being ignored?

    3. This is total BS "johafprins", it's other way around, the materialist physicists have funding and attention...while those "hallucinating" physicist (as you call them) have very little funding until now (2017-2018). And that's because those investors know that there is something to study.

  2. There can not be an infinite number of universes because there wouldn't be any place big enough to put them all.
