Neil and a Particle Physicist Discuss Why There’s Something Instead of Nothing

From smart AI assistance to powerful productivity tools, you can download Opera today: https://opr.as/Opera-browser-StarTalk Why was there more matter than antimatter left over? Neil deGrasse Tyson and comedian Chuck Nice explore the quantum origins of the universe, charge parity violation, dark matter, and the many quarks that make up our world with CERN particle physicist Harry Cliff. We take a look at the Large Hadron Collider (LHC) and his work in studying b quarks (or “beauty quarks”) and sifting through mountains of data to identify new phenomena. We break down the 17 known fundamental particles—including six quarks, three electron-like particles, and three neutrinos. What particles are yet to be uncovered? Could that be the answer to dark matter? As we dive into the early universe, we explore how matter and antimatter formed in nearly equal amounts, only for matter to triumph in a cosmic imbalance. What conditions created this asymmetry? We discuss CP violation and the other laws of nature that the universe may have broken to create itself. Harry also dives into the lifespan of particles, from the fleeting existence of most, to the surprising stability of protons and electrons. Learn how particle discoveries evolved, from Henri Becquerel’s observation of radioactivity to Karl Anderson’s discovery of antimatter in cosmic rays. We also explore how Einstein’s theory of relativity applies to particle accelerators, where particles moving near light speed experience time differently. Could these machines create a micro black hole? Harry explains why media fears of “destroying the universe” are unfounded and why the cosmos has been conducting such experiments for billions of years. Finally, we tackle questions about dark matter, its presence in everyday life, and the hypothetical tachyons that could travel faster than light. Through it all, Harry sheds light on the quantum fields underpinning reality, revealing how particles are ripples in these invisible forces. With insights from his books, How to Make an Apple Pie from Scratch and Space Oddities, Harry guides us through the thrilling world of particle physics, showing how much we’ve learned—and how much more there is to discover.
