parallel worlds

Parallel worlds, or parallel universes, refer to the idea that other realities exist alongside our own, each with its own version of events and outcomes. This concept arises from theories in physics, particularly in quantum mechanics and cosmology. It suggests that for every decision or event, there might be a branch where different choices lead to different realities. While these ideas are often found in science fiction, some scientists explore them as potential explanations for the complexities of our universe. However, as of now, there is no direct evidence of such worlds existing.
