Why Particles Don't Exist Until You Ask the Question | Richard Feynman

What if the particles that make up reality don't actually exist until you ask a question about them? In this mind-expanding lecture, Richard Feynman explores one of the strangest discoveries in quantum physics: particles behave less like tiny objects and more like possibilities waiting to be observed. From the famous double-slit experiment to the mysteries of quantum measurement, Feynman reveals why the universe operates in ways that completely challenge common sense. Discover how observation affects reality, why certainty disappears at the quantum level, and what modern physics teaches us about the true nature of existence. This fascinating explanation takes you deep into the heart of quantum mechanics and shows why Feynman considered it one of the most profound mysteries in science. If you've ever wondered whether reality exists independently of observation, this lecture will transform how you think about the universe. 🔔 Subscribe for more physics, cosmology, quantum mechanics, and science lectures from the world's greatest thinkers.
