,How do particles get mass? Neil deGrasse Tyson and comedian Chuck Nice discover squarks, sneutrinos, the Higgs boson, and whether dark matter has a particle with theoretical physicist Brian Greene. Go to https://ground.news/startalk to stay fully informed on Space and Science news. Save 40% off through my link for unlimited access to the Vantage plan this month. Can we finally get to the bottom of what happens when a quark falls into a black hole? Learn about the ultraviolet catastrophe, the start of quantum physics, and Max Planck quantizing packets of energy. We also discuss how Einstein won the Nobel prize for the discovery for which he is least famous. We take a deep dive into the Higgs boson. Who’s Higgs? What’s a boson? Find out about how the Higgs field creates mass, the different quantum particles, and how quarks create protons and neutrons. Brian breaks down the theory of supersymmetry: does every particle have a counterpart? Learn about squarks, sneutrinos, and whether supersymmetry can give an answer to what dark matter is. Is the fabric of spacetime woven by tiny wormholes? Discover the Casimir force, quantum fluctuations, and why you need so many dimensions in a string theory universe. We discuss whether the cosmological constant is, in fact, constant. Plus, find out about the biggest mismatch between theory and experiment in physics.

,What does science say about alternative medicines and health fads? Neil deGrasse Tyson and co-hosts Chuck Nice and Gary O’Reilly learn about the science behind what alternative medicine can and cannot do with director of National Center for Complementary and Integrative Health, Helene Langevin, M.D. Do any alternative medicines have scientific backing? Are we completely at the mercy of influencers for health advice? What is “complementary medicine”? Learn about how many vitamins you should be taking and whether you need them at all. How do you keep up with changing health research? We discuss supplements and meal replacement. Can food really be replaced? We break down acupuncture and what it does and doesn’t do. Why would someone in pain want to get stabbed by needles? How does the placebo effect work? Does it work? We explore cold therapies like cold plunge and the effect of physiological stress. Is sitting down the new smoking? We talk about the role of stretching and what it does for your connective tissue. Can you stretch too much? What happens if you don’t move? We discuss inflammation and its role in healing. How can our healthcare system help improve overall health? Plus, is natural always good and artificial always bad? Thanks to our Patrons Patrick, Tylré Livingstone, Claire Sims, Terrel Kimber, tinybird, Shawn Hugo, Chris Trent, Deborah Lagutaris, Steve Doom!, and Brian Lopez for supporting us this week.
