Quantum mechanics is such a strange and anti-intuitive field of research that famous physicist Richard Feynman once exclaimed: "I think I can safely say that no one understands quantum mechanics."
Attempts to explain some of the most bizarre consequences of the theory have led to some concepts that really confuse the mind, such as the interpretation of Copenhagen and the interpretation of many worlds .
More recently, a new theory has been proposed , that of the "many worlds that interact," and the idea is just as the name suggests. The theory suggests not only that parallel worlds exist (more precisely, parallel universes), but that they interact with each other quantitatively and hence hypothetically measurable.
Although it is only hypotheses, the theory could finally help explain some of the bizarre results of quantum mechanics.
This is an alternative to the interpretation of many worlds, which provides that all developments in an event and all possible future are real, and each one represents a parallel world.
The problem of this theory is obviously not demonstrable, since observations can only be made in our world, the one we are in.
The new theory of interactive worlds, however, differs from this by affirming that parallel worlds can interact with one another quantitatively, and in fact do so. Physicist Michael Hall led the writing of the article , along with Howard Wiseman.
"The idea of parallel universes has been around since 1957," explained Howard Wiseman, physicist at Griffith University in Brisbane, Australia. "In the well-known" theory of many worlds, "every universe branches into a series of new universes each time a quantum measurement is performed. All the possibilities are then realized - in some universes, for example, the asteroid that killed the dinosaurs missed the Earth. In others, Australia was colonized by the Portuguese. "
"However, critics question the existence of these universes, since they do not affect ours at all," he added. "With regard to this, our theory of" many interactive worlds "is completely different , as the name suggests."
Wiseman and colleagues proposed the existence of a "universal force of repulsion between adjacent worlds, which tends to make them less similar." Some phenomena of quantum theory could be explained by this force, according to physicists.
"The good thing about our approach is that if there is only one world, our theory is reduced to the traditional laws of Newton's mechanics, and if there is a large number of worlds conforms to quantum mechanics. Half of this concept is something that can not be explained by either of the two theories. "
