Space Nuts Episode 488: Cosmic Curiosities - Primordial Black Holes, Ancient Galaxies, and the Ultimate Lagrange Point
Join Andrew Dunkley, Professor Fred Watson, and Professor Jonti Horner as they tackle intriguing questions from our listeners in this Q&A edition of Space Nuts. Dive into the mysteries of the universe with thought-provoking discussions on primordial black holes, ancient galaxies, and the concept of the ultimate Lagrange point.
Episode Highlights:
- Primordial Black Holes: Rusty from Donnybrook throws a cosmic curveball about the impact of a primordial black hole entering our solar system. Explore the fascinating scenarios and potential consequences with Fred and Jonti as they delve into gravitational dynamics and celestial mechanics.
- Ancient Galaxies: Marcel questions the age of the universe as the James Webb Space Telescope continues to uncover older galaxies. Fred and Jonti unravel the complexities of cosmic timelines and the implications for our understanding of galaxy formation and evolution.
- The Ultimate Lagrange Point: Buddy from Oregon ponders whether the center of a galaxy could be the ultimate Lagrange point. Discover the intricacies of gravitational balance and stability as Jonti explains the concept of Lagrange points and their cosmic significance.
- Expansion of the Universe: Michael from Illinois raises questions about the accelerating expansion of the universe and its effects on our solar system. Fred and Jonti discuss the interplay between cosmic expansion and gravitational forces, offering insights into the future of our universe.
