The Shocking Reason Light Passes Through Glass — Nobody Taught You This

You look through glass every single day. Windows. Phone screens. Glasses. Bottles. But if you hold a brick wall up to your eyes — nothing. Complete darkness. Both are solid objects. Both are made of atoms. So why does light pass through one and completely stop at the other? The answer is hidden deep inside the atoms themselves — and once you understand it, you will never look at a window the same way again. In this video we explain: ✅ What light actually is and how it interacts with matter ✅ Why glass lets visible light pass straight through ✅ Why walls, wood, and metal completely block light ✅ Why glass blocks UV light but not visible light ✅ How X-rays pass through your body but not your bones ✅ Why diamond is transparent but graphite is not — same element, opposite result
