In 1954, a young PhD from the University of priston, Hugh Everett III, proposed quite an amazing assumption that in the galaxy there are parallel universes identical to our universe. According to his point of view, all these universes are connected with our universe, but at the same time, they all deviate from our universe, and our universe in turn is rejected from all others. Probably in other universes too, was their war, which may have had a somewhat different character than those that have occurred on our planet. Some living organisms, dead in our universe, to evolve and to adapt to different conditions in another universe. It is possible that in other galaxies are none of the people, because in those conditions people could simply not survive.

This idea dominates our consciousness, though, seems quite likely. Notions of parallel universes or dimensions that resemble our own world, appeared initially in the literature, primarily in science fiction. But why would a young and promising physics to risk his future career, spreading all sorts of stories expounding a theory about parallel universes?

Placing theory on the existence of multiple worlds, Everett tried to give the very exciting question related to quantum physics: Why is the amount of matter behaves irregular and disorderly? In fact, quantum science at the moment is just developing and at this stage there are more questions than answers. The study of quantum physics began in 1900, when physicist Max Planck proposed to allocate another section in physics and call it quantum physics. During one of his experiments, Planck found a strange behavior of the radiation that was completely contrary to classical laws of physics. These results showed that in the universe there are other, not yet driven us laws, so why can not exist in different universes?

Physicists studying the quantum level noticed some peculiar things about this tiny world. First, particles that exist at this level, can change different shapes. For example, scientists have observed the photons - tiny bundles of light. Even a single photon exhibits its ability to take different forms. This can be represented in the form as if You were a normal whole person suddenly and can take gaseous form.

This phenomenon became known as the Heisenberg's uncertainty principle. Physicist Werner Heisenberg argued that simply observing quantum matter, we affect the behavior of this substance. So we'll never know for certain the true nature of a quantum object or its properties, such as speed and location.

This view is supported by scientists from the Copenhagen Institute of quantum mechanics. According to the definition of the Danish physicist Nils Bohr, "all quantum particles can exist in one or the other as they exist in all possible States at once. The total number of possible States of a quantum object is called its wave function. The state of the object simultaneously in all its possible States is called a superposition (overlay)".

According to Bohr, when we observe a quantum object, we affect its behavior. Surveillance violates the superposition of the object and usually causes the object to assume one of its States in the wave function. This theory explains why physicists have turned out different data of the same quantum object each time the object is "selected" different States.
