The so-called ‘Many Interacting Worlds Theory’ argues that multiple universes coexist in the same space and time as our own. Scientists believe that these even interact on a quantum level.
The idea of Parallel universe has captured the imagination of many experts around the globe. The idea of a parallel universe has given birth to numerous movies and even TV series. However, there could be more about the Parallel universe than just science fiction.
According to Howard Wiseman of Griffith University in Australia and his team, a new groundbreaking theory indicates that multiple universes coexist in the same space and time as our own. Interestingly, scientists believe that these even interact on a quantum level. The study was published in the journal Physical Review X.
The paper basically introduces ‘Many Interacting Worlds’ theory as an alternative to the more famous ‘Many Worlds’ theory that was proposed in the 1950s.
The ‘Many Worlds’ theory speculated that after an event occurs, several universes arises offering all possible outcomes for given event.
These universes are believed to exist parallel to ours in a separate space, and at the same time, never interacting. This, however, is wrong according to the ‘Many interacting Worlds’ theory, as the name clearly indicates.
The Many interacting Worlds theory suggests that all of the multiple worlds overall and occupy the same space and time at once, just like a quantum state.
“All possibilities are therefore realized – in some universes the dinosaur-killing asteroid missed Earth. In others, Australia was colonized by the Portuguese,” Wiseman said in a press release. “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.”
The theory presupposes that there could be worlds in the parallel universe that are nearly identical. Others are entirely different, and the so-called ‘Butterfly effect’ is responsible for different outcomes. Furthermore, each universe is considered a reality.
The similarities that may exist between worlds interact through quantum forces which on the other hand influence the outcome of a world by making them somewhat dissimilar.
Interestingly, Wiseman argues that while the theory states that different worlds interact with one another on a quantum level and not larger scale, the new theory DOES NOT make it impossible.
The response within the scientific community is mixed. There are those who argue that the theory is a huge waste of time as Luboš Motl, while others believe it offers a peculiar and interesting explanation to everything around us.
“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,” Wiseman continued. “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.”
