If the Universe Is Expanding, What Is It Expanding Into? | Feynman Explains

Описание: 🌌 The universe is expanding—but INTO WHAT? Join Richard Feynman in this mind-bending 21-minute journey tackling cosmology's most confusing question! 🔭 Discover the shocking truth: the universe isn't expanding "into" anything—space itself is stretching, creating more space between galaxies. Through Feynman's brilliant analogies, understand how the Big Bang wasn't an explosion in space but an expansion OF space, why "outside the universe" is a meaningless concept, and how curved spacetime eliminates the need for external dimensions. ⚛️ Explore balloon analogies, cosmic geometry, Einstein's general relativity, and why our 3D brains struggle with 4D spacetime reality. Learn about finite yet unbounded universes, cosmic horizons, and what "edge of the universe" actually means. 💫 Perfect for anyone frustrated by cosmology's counterintuitive truths! This permanently clarifies expansion's most confusing aspect. #Cosmology #Universe #Feynman
