The sensational claim was made by a team of physicists, who believe that the parallel universes can all affect one another.
Professor Howard Wiseman and Dr. Michael Hall, from Griffith University’s Centre for Quantum Dynamics, claim that the idea of parallel universes is more than just science fiction.
Fellow researcher Dr. Dirk-Andre Deckert, from the University of California, helped further the researchers’ theory, which goes against almost all conventional understanding of space and time.
If there really are multiple, interacting universes, then it would be possible for time travelers to visit Earth, and every imaginable scenario would be played out in a parallel universe at some point.
The team’s ‘Many Interacting Worlds Theory’ provides a whole new perspective on the ideas underpinning quantum theory, a notoriously complex strand of physics.
Professor Wiseman said: “The idea of parallel universes in quantum mechanics has been around since 1957.
“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 realized – in some universes the dinosaur-killing asteroid missed Earth. In others, Australia was colonized by the Portuguese.
“But critics question the reality of these other universes since they do not influence our universe at all.
“On this score, our ‘Many Interacting Worlds’ approach is completely different, as its name implies.”
According to the theory, our universe is just one of many enormous worlds, with some identical to our reality and others completely different.
The Express reports that the worlds are all real, and all on the same timeline, but interact when they essentially bump into each other.
Dr. Hall believes that the group’s sensational theory fits with current scientific understanding, offering a new perspective rather than rewriting the physics rulebook completely.
He said: “The beauty of our approach is that if there is just one world our theory reduces to Newtonian mechanics, while if there is a gigantic number of worlds it reproduces quantum mechanics.
“In between, it predicts something new that is neither Newton’s theory nor quantum theory.
“We also believe that, in providing a new mental picture of quantum effects, it will be useful in planning experiments to test and exploit quantum phenomena.”
Also, a different team of researchers made the sensational claim that humans have souls which can live on after death.
