Space Nuts Episode: Radio Interference, Multiverse Viability, and
Martian Water Behaviour

Join Andrew Dunkley and Professor Fred Watson in this intriguing
Q&A edition of Space Nuts, where they tackle a variety of
thought-provoking questions from listeners. From the challenges of
radio astronomy in urban areas to the fascinating possibilities of
multiverse sizes, this episode is packed with cosmic
insights.

Episode Highlights:

Radio Interference and Urban Astronomy: Tobias from
Marsfield, Sydney, asks about the viability of radio astronomy
near urban areas, specifically at the CSIRO astrophysics lab.
Fred discusses the impact of terrestrial radio interference and
the transition to LED street lights on astronomical observations.

- Multiverse Viability: Jeffrey inquires about the smallest
possible size for a viable universe in a multiverse scenario.
Fred explores the complexities of universe formation and the
intriguing theories proposed by Roger Penrose.

- Dark Matter and Angular Momentum: Rosie's husband raises
questions about the correlation between gravitational lensing and
dark matter mass measurements. Fred explains how gravitational
lensing helps map dark matter in galaxies and clusters.

- Water Behaviour on Mars: Cam from the Blue Mountains
imagines aquatic leisure activities on ancient Mars. Fred delves
into how water would behave in Mars' lower gravity, including
swimming, splashing, and the potential for belly flops from great
heights.
