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.
