Universes (parallel)

Parallel universes, or the idea of a multiverse, suggest that our universe might be just one of many. These other universes could have different physical laws, constants, or histories. Imagine an infinite number of realities, each with its own version of events and existence. In some theories, these universes are separate and cannot interact; in others, they might influence each other at the edges. While there's no definitive proof, the concept helps explain mysteries like fine-tuning and cosmic coincidences, expanding our perspective of reality beyond what we directly observe.
