Space Nuts: Q&A on BepiColombo, Neutrinos, and Time
Dilation

In this Q&A edition of Space Nuts, hosts Andrew
Dunkley and Professor Fred Watson dive into a series of intriguing
listener questions that span topics from the nuances of orbital
velocity to the enigmatic world of neutrinos and the complexities
of time dilation. Join them as they unravel these cosmic queries
with their signature blend of insight and humour.

Key topics

- Larry from Nebraska asks about the BepiColombo mission and the
relationship between gravitational assists and orbital velocity,
prompting a discussion on how spacecraft navigate the solar
system.

- Eduardo explores the nature of neutrinos, questioning whether
they are affected by gravity and whether they can be trapped by
black holes.

- Shumo presents a thought-provoking idea about using high-energy
gamma rays or neutrinos as interstellar beacons, leading to a
discussion on the potential for advanced civilisations to
communicate through unconventional means.

- Colin from Adelaide raises questions about time dilation effects
as depicted in the science fiction movie "Project Hail Mary,"
specifically the implications of travelling close to the speed of
light and the resulting age differences upon return to Earth.
