Wohin GEHT das Licht am Ende des Universums? - Feynmans verblüffende Erklärung | Richard Feynman

What if the light upon which our entire perception of reality is based doesn't exist forever? And what if the universe itself one day extinguishes every trace of light, plunging the cosmos into a darkness deeper than anything we can imagine? 🌌 In this video, we explore one of the most unsettling mysteries of modern cosmology: the ultimate fate of light. Drawing on Richard Feynman's way of thinking, we follow photons on their journey through an expanding universe, discovering the true meaning of cosmological redshift, dark energy, cosmic horizons, and the heat death of the universe. Why do photons lose their energy? What happens to light that is swallowed by black holes? And could reality itself one day leave every observer and every form of information behind? This video connects quantum mechanics, relativity, entropy, and the deepest questions about existence, observation, and the nature of spacetime. ✨ Subscribe to our channel so you don't miss any fascinating videos about the physics of our universe, and if you'd like to support our work, you can show your appreciation with a Super Thanks. 🔔 SUBSCRIBE: https://www.youtube.com/@FeynmansWeg?...
