Si la Masa Crea la Gravedad, ¿Qué Obliga al Espacio-Tiempo a Curvarse? | Richard Feynman

If Mass Creates Gravity, What Forces Spacetime to Curve? | Richard Feynman In 1949, Richard Feynman asked his professor, John Wheeler, a question that left him speechless. It wasn't a difficult question to calculate. It was a question no one had dared to ask seriously: "Mass curves spacetime. The equations work. But... how exactly? What's between mass and geometry?" That night, Wheeler wrote in his notebook: "Feynman asked the right question." Seventy-five years have passed. We still don't have the answer. But pursuing that question reveals five discoveries no one has told you about—and the last one suggests that the end of the universe and its beginning could be the same instant. 🌌 In this video you will discover: → Why the elastic fabric analogy you were taught in school destroys itself → Newton's private confession: he didn't understand his own theory either → Why 99% of your mass doesn't come from matter, but from trapped energy in motion → How your phone's GPS depends on time passing more slowly near Earth → The paradox that blows up the equations when gravity and quantum mechanics collide → Why mass needs time to exist... but destroys it when it's too big → How the end of the universe, without mass and without time, is indistinguishable from its own beginning 📚 Based on: — The Feynman Lectures on Physics (Vol. 2) — The Character of Physical Law — Messenger Lectures, 1964 — Six Not-So-Easy Pieces (Relativity and Spacetime) — Feynman & Wheeler: Princeton, 1949 🔔 Subscribe for more in-depth explanations of quantum mechanics, relativity, and the mysteries of the universe 👍 Like if this changed your understanding 💬 Comment: Which of the five discoveries impacted you the most? 🔬 Feynman Physics – Where Clarity Meets Wonder In-depth explanations of physics based on Richard Feynman's original lectures.
