Scientists in Australia appear to have come up with a plausible parallel universe explanation

In a paper appearing in “Physical Review X” a few years ago appears to bring credible science to the theory. Michael Hall and his team from Griffith University suggest we live within “Many Interacting Worlds” (MIW).


Science vs Science Fiction

It is an idea that is constantly explored in literature, film, and TV. Currently TV shows like “Stranger Things” portray an interaction between parallel worlds.

Theoretical physicists such as Hugh Everett have proposed such hypotheses since the 1950s. And now these ideas seem to be measuring up to the complicated mathematics of quantum physics.

Hall and his team have sought to bridge the gap between classical Newtonian physics and quantum mechanics. According to the paper, parallel universes seem to be that bridge.

The physicists work with the premise that for every action, a reaction occurs

However, they claim that each reaction branches out into an alternative universe. The idea is that there are an enormous number of universes layered like thin pancakes upon each other.

This, they explain, measures up with the atomic observations. What occurs inside an atom is not determinable before an experimenting upon it. And each theoretical universe is not determinable until realizing a potential outcome.


Quantum physicists claim that particles within an atom can have upper and lower spins simultaneously

They also appear in multiple places at once. However, in our real world reality, these rules don’t apply. Our everyday world appears Newtonian.

They argue, that if we have multiple worlds constantly branching out, then this is why we observe the activity of particles as we do. On a particle level, they hypothesize, we are viewing the multiple worlds playing out simultaneously.


Opponents and Skeptics

A healthy scientific inquiry is rife with debate and skeptical analysis of proposed hypotheses. There are many theoretical physicists who oppose the MIW theory.

String Theory proponent, Luboš Motl claims that the entire paper is a “hopeless enterprise and a huge waste of time“.

The alternative idea of string theory proposes that multiple dimensions collapsed with the Big Bang. The collapsed dimensions supposedly explain the strange particle activity at the quantum level.

Another string theorist, Brian Greene, also warns about jumping to conclusions about MIW. As well as the hypotheses he has come to, he has stated clearly that for all of these there is no proof. We must maintain skepticism.

The main thing we know is that we don’t know much at all. The more questions that scientists dive deeply into trying to understand, the less they realize they know.


When The Theories of Scientists Become Reality

But this is an exciting thing. The theories proposed by these scientists are still profound. The concept of black holes was hypothetical for generations. And now we can observe their actions in outer space. They behave how the predictions expected them to.

Not only that, we can now locate black holes and seek to understand them better.

Are there parallel worlds coexisting in front of our noses? We have no tangible proof. Are there more dimensions than the 3 we live within – 4 if you count time? No scientist could present you with evidence.


Great minds in every generation seek answers to the questions that remain insatiable to their curiosity

Their genius can see clues that a layperson cannot. Maybe 30 years from now we will know if there are other dimensions – or other universes.

For the time being, we should remember the stage of understanding that we remain at. As renowned theoretical physicist Richard Feynman once said:

“I think I can safely say that nobody understands quantum mechanics”.
