Does the Future Already Exist? What Richard Feynman Revealed About Time

Does tomorrow already exist somewhere in the universe? Is your future self out there right now? In this video, we explore one of physics' deepest mysteries: the nature of time itself.
We'll journey through Einstein's relativity, quantum mechanics, and the mind-bending "block universe" theory to understand whether the future is already written or still being created. You'll discover why physicists think all moments in time might exist simultaneously, what this means for free will, and how GPS satellites prove time is stranger than you ever imagined.
No advanced science knowledge needed - just curiosity about how reality really works.
