Quantum Field Theory: What Is the Universe Actually Made Of?

🎧 Enjoy listening without watching the screen? You can also find The Sleepy Scientist on Spotify: https://open.spotify.com/show/0340wK7... What is the Universe really made of? Beneath the familiar world of atoms and particles lies an extraordinary description of reality in which invisible quantum fields exist throughout space, and the particles we observe are excitations of those fields. In this gentle exploration of quantum field theory, we uncover why every electron is identical, how particles can be created and destroyed, why even empty space has quantum properties, and how the Higgs field, electromagnetic interactions and the strong and weak nuclear forces help shape everything around us. Along the way, we examine the remarkable experiments that established our modern understanding of matter and the mysteries that remain, including quantum gravity and the possibility of something deeper than the fields themselves. Make yourself comfortable, unwind, and discover the fascinating physics beneath the ordinary appearance of our Universe.
