Answering Questions About Why the Big Bang Happened, The Shape of the Universe & More

Could slowing time increase mass? Do particles ever collide or do they just get really really close? Did anything go “bang” during the Big Bang? Neil deGrasse Tyson, co-host Paul Mecurio, and astrophysicist Charles Liu tackle these cosmic questions and more! Shouldn’t the vacuum of space cause interstellar gas clouds to disperse evenly? We break down how diffusion works and how different forces come together to keep gas clouds intact. What’s in these clouds, and why does some gas get left behind during star formation? Next, we confront the Big Bang itself: what exactly went “bang”? We dive into the misconceptions surrounding the term and its origins with Fred Hoyle. What can we learn from gravitational waves beyond just detecting them? We explore the structure of spacetime and the speed of gravity. How do gravitational waves offer a deeper understanding of the universe’s invisible framework? Could slowing down time increase mass? We discuss the manipulation of time and the nature of scientific inquiry. As the discussion turns to cosmic collisions, we explore how galaxies interact without stars ever touching. Do particles ever collide or do they just get really really close? What forces govern these interactions, and how do fields and forces influence the behavior of matter? Charles reveals the almost magical dynamics of gravitational and electromagnetic forces, while Neil ties it back to Newton and Einstein. Finally, we look back in time to the earliest generations of stars. How do we study stars that existed billions of years ago, and what did these stellar giants sacrifice to forge the elements of life? Charles delivers a heartfelt tribute to these cosmic ancestors, reminding us how the light of the past illuminates our understanding of the universe today.
