Cosmic Questions: The Emptiness of Space and Tidally Locked Planets
In this enlightening Q&A episode of Space Nuts, hosts Andrew Dunkley and Professor Fred Watson tackle an array of intriguing listener questions. From the vast emptiness of space to the peculiarities of tidally locked planets, this episode promises to expand your cosmic curiosity.
Episode Highlights:
- How Empty is Space? Kevin's question leads to a discussion on the remarkable emptiness of space and the risks faced by spacecraft like New Horizons. Fred Watson explains the varying densities of space, from the dusty inner solar system to the clearer outer regions, and how spacecraft navigate these vast distances without colliding with debris.
- Tidally Locked Planets: Casey asks about the implications of tidally locked planets on the formation of compounds and molecules. The hosts explore the temperature extremes on such planets and the potential for a habitable zone at the terminator, where the hot and cold sides meet.
- Sonification of Orbits: Hazel from Scotland inquires about the musical adaptations of orbits and whether galaxies experience similar resonances. Fred Watson elaborates on the fascinating concept of orbital resonances and how they can be translated into sound, while also addressing the complexities of galactic motion.
- Peculiar Motions in the Universe: Rusty poses a thought-provoking question about the peculiar motion of the Local Group towards the Virgo Cluster and the Great Attractor. Fred Watson discusses the early universe's structure and how dark matter filaments contribute to the motion of galaxies.
