Parallel Worlds in Science Fiction: From Theory to Practice

The concept of parallel universes has long inspired the minds of science fiction writers. In recent decades, however, this idea has increasingly attracted the attention of scientists who see it as a potentially real possibility.

Scientific theories of parallel worlds
Everett's interpretation
One of the first to seriously consider the idea of a plurality of worlds was theoretical physicist Hugh Everett. According to his interpretation of quantum mechanics, each act of measurement or choice leads to the branching of reality into several parallel versions.


Hawking cosmology
Stephen Hawking, one of the greatest theoretical physicists of the twentieth century, also suggested the existence of an infinite number of parallel universes. According to his model, they can differ in the laws of physics, time, size and other fundamental characteristics.


String Theory and the D-Bran
Current superstring theories and M-theory allow for extra dimensions of space-time in which other worlds parallel to our own may exist. These worlds can interact with each other through special objects called D-branes.


Parallel Worlds in Science Fiction


The idea of parallel universes regularly appears in science fiction. The authors use this concept as a basis for fascinating plots and experiments with reality:

• The Multiverse (2022) – Travels between Parallel Realities
• Rick and Morty (2013–present) – Adventures in the Infinite Multiverse
• The Dark Tower (2017) – the transition between worlds in a fantastic Western
• Steven's Universe (2013-2019) - young hero explores parallel dimensions

The idea of parallel worlds is fascinating because it promises limitless possibilities, both for scientific discovery and for the flight of fantasy. — Dr. Michael Greenberg, theoretical physicist


Prospects for practical application

While travel between parallel universes remains a science fiction endeavor, some scientists believe it may become a reality in the future. Possible areas include:

• Exploring alternative versions of history and events
• Finding resources and solutions to problems in other dimensions
• Creating backup copies of humanity in case of disasters
• Experiments with the laws of physics in other realities

Despite the fact that the concept of parallel worlds is still far from practical implementation, it continues to capture the minds of scientists and science fiction, offering endless opportunities for further research.
