Cosmic Queries – Dimensional Leaking

About This Episode

Is the whole universe actually a jinn particle? Neil deGrasse Tyson and cohosts Chuck Nice and Gary O’Reilly hang out with astrophysicist Charles Liu to answer questions about the nature of gravity, dark matter, and why we don’t actually know how the solar corona gets hot.

We explore some of the universe’s deepest mysteries: could dark matter be matter leaking from other dimensions? What happens before black holes collide? And are gravitational waves just the beginning of our understanding of cosmic communication? We break down the known forces in the universe, their corresponding particles, and why gravity is different. Is gravity a force, a curvature, or just semantics? And if gravity is a force, where’s the graviton?

We spiral into extra dimensions, frame dragging, and why gravity could be the only force that doesn’t respect spacetime boundaries. If gravity could leak from parallel dimensions, what else can? Plus, can we explore Europa’s ocean without contaminating it? Are people rethinking Einstein’s theory in light of new supernova data? We discuss the ethics of ice fishing for alien whales and the enduring lessons of Copernicus.

Finally, what can the Parker Solar Probe teach us about our Sun and other stars beyond? Does the solar corona actually feel that hot? Learn about the unsolved mysteries of the photosphere and why an iceberg has more heat than your morning cup of coffee. Could our universe be part of a continuous time loop?
