WHY DO YOU EXIST? The Mystery of Matter vs. Antimatter That Saved the Universe

Why is there something rather than nothing? If matter and antimatter were meant to annihilate each other at the birth of the cosmos, how did enough matter survive to form you, me, and all the galaxies? In this episode of Cosmic Frontiers, we dive deep into the enigma of matter-antimatter asymmetry – the profound mystery that literally saved the universe from becoming an empty void of pure energy. Join us as we explore: What are matter and antimatter, and why do they mutually annihilate upon contact? Why the Big Bang should have produced equal amounts of both, leading to universal annihilation. The universe's incredible "leftover": roughly one part in a billion of matter. Andrei Sakharov's three crucial conditions for baryogenesis: baryon number violation, CP violation, and thermal non-equilibrium. Leading proposed scenarios to explain this asymmetry: electroweak baryogenesis, leptogenesis, and more. The cutting-edge experiments at facilities like CERN, where scientists are tirelessly searching for clues to this cosmic imbalance. Understanding matter-antimatter asymmetry isn't just about cosmic history; it's about our very existence and the fundamental laws that govern the universe. Without this slight imbalance, the cosmos as we know it would never have formed. What are your thoughts on this cosmic mystery?
