Space Nuts Episode 502: Q&A on Black Holes, Cosmic
Temperatures, and Starshot Missions

Join Andrew Dunkley and Professor Fred Watson in
this engaging Q&A episode of Space Nuts, where they tackle a
variety of intriguing questions from listeners around the globe.
From the mysteries of black holes to the minimum temperature of
space and the ambitious Starshot mission, this episode is packed
with thought-provoking insights and lively discussions.

Episode Highlights:

- Black Hole Plasma Beams: Listener James from New
Orleans sparks a fascinating discussion about plasma beams
emanating from the M87 black hole and the recycling of matter in
the universe. Andrew and Fred explore the implications of cooling
plasma and its potential to change states.

- Minimum Temperature of Space: Buddy from Morgan
raises a thought-provoking question about whether the minimum
temperature of space will continue to drop as the universe expands.
The duo dives into cosmic background radiation and its effects on
the elements in the universe.

- Light and Gas Pressure: Jacob from Western
Australia asks whether gas pressure can affect light. Andrew and
Fred clarify the relationship between light, pressure, and the
fascinating phenomenon of light refraction.

- Starshot Mission Hypotheticals: Ash from
Brisbane presents a mind-bending hypothetical about launching a
micro spacecraft to Alpha Centauri at a right angle to the galactic
plane. The team calculates the time it would take to observe our
galaxy from the outside, revealing the vastness of space
travel.
