Your PAST Is Still Happening Right Now — Feynman on Relativity

Описание: What if the moment you were born is still happening — right now — somewhere in the fabric of reality?
Einstein's relativity doesn't just bend time. It dismantles the idea that time is a flowing river with a universal "now." Two people walking past each other on the street can disagree — by days — about what's happening in a distant galaxy at this very instant. If "now" is that fragile, what does it mean for the past to be "gone"?
In this video, we explore what special relativity actually tells us about the nature of past, present, and future — drawing from Feynman's explanations in The Feynman Lectures on Physics, Einstein's original 1905 paper on electrodynamics, and Penrose's Andromeda thought experiment. We trace the physics from the constancy of light speed through time dilation, the relativity of simultaneity, the muon survival experiment, and arrive at the staggering implication of the block universe.
