In this episode:
- John asks about the implications of Mars' longer day length on human biology and potential adaptations for future colonists.
- Dan inquires about the growth of black holes, exploring how quickly they can develop into supermassive entities and what happens when there’s nothing left to consume.
- Young Thomas, just 11 years old, poses several intriguing questions about the galactic centre, including whether it can swallow all stars and planets in the galaxy, and the limits of a black hole's gravitational reach.
- Paul reflects on historical discoveries in astronomy, specifically how Harlow Shapley determined our Sun's position within the Milky Way, challenging the long-held belief that it was at the centre.
Join Andrew and Fred Watson as they explore these thought-provoking questions and more, encouraging listeners to continue their journey of exploration and discovery in the universe.
