Parallelworlds

Parallel worlds, also known as alternate realities or alternate universes, refer to the hypothetical existence of realities that coexist with our own but differ in some way, such as in their timeline, geography, or fundamental laws of physics. The concept is prominent in various fields, including science fiction, philosophy, and physics. In Hebrew, the term is translated as עולמות מקבילים (Olamot Mekabalim). In Spanish, it is mundos paralelos, and in French, it is mondes parallèles. The idea of parallel worlds has been explored in numerous cultural works, such as the film "Sliding Doors" and the TV series "Doctor Who". In theoretical physics, the concept is related to the many-worlds interpretation of quantum mechanics, proposed by Hugh Everett in 1957, which suggests that all possible outcomes of quantum measurements become real in some "world" or universe.
