multiverse

Multiverse is a concept in theoretical physics that suggests that there may be multiple universes or parallel realities that exist alongside our own. These other universes may have different physical laws, dimensions, and even different histories. The idea of a multiverse is often used to explain certain phenomena that cannot be explained by our current understanding of the universe, such as the fine-tuning of physical constants or the existence of dark matter. While there is currently no concrete evidence for the existence of a multiverse, it remains an intriguing and controversial area of study in physics
