How Many Multiverses Are There? | Space Documentary 2026

What if there’s a world out there with the same Earth—the same oceans, cities, and stars—but another version of you walks its surface? Maybe they live a different life, make different decisions, yet share your face, your memories, your mind. And there are not one, but a countless universe of you, each living another possibility. We’ve seen this idea in movies and comics for years, but now physics is starting to take it seriously. Could all those other worlds, and countless versions of you, actually exist out there? #space #universe #spacedocumentary Credits: NASA ESA: https://www.esa.int/ESA_Multimedia/Im...
