Why You've Never Actually Touched Anything | Full Lecture

You've never actually touched anything. Every surface you think you've touched—you haven't. What you feel isn't contact. It's electromagnetic repulsion. In this lecture, we explore what matter really is: atoms that are 99.9999999999999% empty space held together by invisible forces. You'll learn why nothing is actually solid, what "touching" really means at the atomic level, and why your brain creates the illusion of solidity to help you navigate the world. Topics: atomic structure, electromagnetic forces, empty space in matter, the physics of touch, why solidity is an illusion, and why you can't walk through walls despite matter being mostly nothing. This is Lecture 3 in the Foundations of Science series. --- 📚 Foundations of Science | Dr. James Mitchell University-level physics lectures presented clearly and thoroughly.
