Join Andrew Dunkley and Professor Fred Watson in this lively
Q&A episode of Space Nuts, where they dive into a variety of
intriguing questions from our audience. From the mysteries of lunar
lava tubes to the wonders of black holes and gravitational waves,
this episode is packed with fascinating insights and cosmic
discussions.

Episode Highlights:

- Lunar Lava Tubes: Discuss the potential hazards that lunar
lava tubes might pose for future moon missions. Explore the
implications for astronauts traversing the moon's surface and how
NASA might mitigate these risks.

- Black Hole Conundrums: Tackle a thought-provoking question
about the behaviour of light within a black hole. Discover the
complexities of singularities and the fascinating concept of frame
dragging in rotating black holes.

- Gravitational Waves and Cosmic Expansion: Delve into the
nature of gravitational waves and their impact on our understanding
of the universe. Learn whether these waves could influence cosmic
phenomena like gravitational lensing and the expansion of the
universe.

- Instatravel Pod Adventure: Imagine a journey to any
location in the universe with a hypothetical instatravel pod. Join
Andrew and Fred Watson as they share where they would go and why,
from viewing the Milky Way from afar to discovering intelligent
life on another planet.
