About this episode
Join Andrew Dunkley and Professor Fred Watson in this lively Q&A episode of Space Nuts, where they tackle fascinating questions from listeners about the universe's expansion, three sun systems, black hole mergers, and coronal mass ejections.
Episode Highlights:
- Universal Expansion: What if the expansion of the universe slowed down? Could light overtake the edge of the universe?
- Three Sun Systems: Chris from North Carolina asks about the possibility of a planet orbiting three suns and the gravitational effects of such a system.
- Black Hole Mergers: Discover what happens when black holes merge. Is it like a mini big bang?
- Coronal Mass Ejections: Have we ever collected matter from a coronal mass ejection? Lee from Canada wants to know the details and implications.
