The theory of parallel universes has been illustrated repeatedly in science fiction, without any actual proof that they really exist. Howard Wiseman of Griffith University in Australia directed a group that believes quantum theory permits for multiple forms of our universe to happen and even interact with one another in the quantum realm. Michael Hall is the chief author of the paper, issued in the journal Physical Review X. Learning the nuances of quantum theory can get very complicated, as things act different to what would be projected from normal matter.

Quantum states of a structure are supposed to concurrently occur in all imaginable formations until an observer forces it to implement one state. In the mid of 20th century, the ‘Many Worlds’ theory initially guessed that multiple forms of reality branch out from one another as separate entities surviving in separate positions, lacking any interaction with each other. According to this new theory; all of these endless multiple universes overlap and inhabit the similar section of time and space concurrently, exactly like a quantum state.
Wiseman, in a press release, said “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 this new explanation, certain realms in parallel universes would be approximately duplicate. But in others, the “Butterfly Effect” is accountable for totally different conclusions. Each universe is correspondingly real; it isn’t like that one universe is the reality whereas others are bizarre duplicates or slighter in any way.
Wiseman also considers that the quantum forces accountable for motivating this mutual existence are also accountable for initiating quantum interactions among the worlds. Likeness between worlds interrelates through quantum forces, which affects the result of the world by constructing them faintly different. However the theory also states that these worlds interact with one another only on the quantum realm and not on a bigger scale, Wiseman also considers the theory does not prevent that option, either.
Wiseman 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.”
Reply from the physics community has been mixed. Luboš Motl described Wiseman’s study as “a miserable enterprise and a huge waste of time.” On the other hand Charles Sebens from the University of Michigan is more aligned with Wiseman’s concept. By means of a different track of thinking, he approached to a very parallel decision and told Nature: “They give very nice analyses of particular phenomena like ground-state energy and quantum tunneling.”
Obviously, the big problem now is defining how Wiseman’s concepts can be tested and how to identify quantum deviations that might specify contacts with another world.
