The multiverse theory suggests parallel realities, but no direct proof exists. The idea of parallel universes, or the “multiverse,” comes from different scientific theories, including quantum mechanics, string theory, and cosmic inflation. Some scientists believe that our universe might be just one of many, each with different physical laws, histories, or even versions of ourselves.
One version of this idea comes from quantum mechanics, where particles can exist in multiple states at once. Some interpretations suggest that every time a decision is made, reality splits into different branches, creating new universes where each possibility plays out. This is known as the “many-worlds interpretation.”

Another theory comes from cosmology. After the Big Bang, space expanded rapidly, and some scientists propose that different regions of space-time could have formed separate universes with unique conditions. These universes would be beyond our ability to observe.
Despite these fascinating theories, no direct evidence proves that parallel universes exist. Testing the multiverse idea is extremely difficult since we can only see our universe. Scientists continue to explore this concept, but for now, parallel universes remain a possibility rather than a proven fact.
