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.
