BR on Instagram: "⚡ Quantum Electrodynamics (QED) is the most precise theory in physics – it explains how charged particles like electrons disturb the universal photon field, exchanging virtual photons that create ripples fading with distance – exactly as Coulomb’s law predicts. 🔬 When electrons move, these ripples bend into magnetic loops, and together they form the electromagnetic field – the single force behind electricity, magnetism, light, radio waves, and even the cosmic structure of our
