Jun 13, 2025
Astrophysicist Charles Liu, co-author of 'One Universe at Home in the Cosmos,' joins Neil deGrasse Tyson and cohosts to explore mind-bending concepts like dimensional leaking and its implications for our reality. They discuss the mystery of gravity, the curious nature of black holes, and the enigmatic temperature differences in the solar corona. Liu also reveals insights from the Parker Solar Probe's findings about the sun, inviting listeners to rethink their understanding of cosmic phenomena and the universe's cyclic nature.

Episode notes
INSIGHT

Gravity: Force vs Curvature

  • Gravity behaves as both a force and curvature of space-time depending on the scale and context.
  • Understanding this duality is crucial for studying extreme environments like black holes and the early universe.

Graviton: Gravity's Particle

  • The graviton is the hypothesized particle that mediates gravity, analogous to photons for electromagnetism.
  • Detecting gravitons is challenging due to their low energy and abundance, but gravitational wave observations imply their existence.

Black Holes Collision Effects

  • Colliding black holes emit gravitational waves with energy release depending on collision specifics.
  • Frame dragging causes different time experiences near each black hole, affecting the merger dynamics distinctly.
