"Antiworlds"

"Antiworlds" refers to hypothetical universes that are the opposite of our own, often discussed in science fiction and theoretical physics. In these scenarios, basic concepts such as time, gravity, or even fundamental forces may behave differently. For example, if our universe expands, an antiworld might contract. This idea challenges our understanding of reality, prompting discussions about the nature of existence and symmetry in the universe. Although purely speculative, it raises intriguing questions about parallel dimensions and the structure of the cosmos.
