Space Nuts: Q&A on Radial Velocity, Dark Matter, and Angular Momentum

In this engaging Q&A episode of Space Nuts, hosts Andrew Dunkley and Professor Fred Watson tackle a variety of intriguing listener questions, ranging from the complexities of radial velocity in exoplanet detection to the mysteries of dark matter and angular momentum in black holes. Join them as they explore these cosmic conundrums with their characteristic wit and expertise.

Key topics

- Hussein from Yemen asks about the radial velocity method for detecting exoplanets, prompting a discussion on how astronomers can isolate individual planets from the combined gravitational effects of multiple bodies.

- Martin from Maryland raises a thought-provoking question on the potential to harness dark energy for space flight, leading to an exploration of the feasibility of accelerating spacecraft to near-light speeds.

- Peter from Sweden inquires about the angular momentum of matter falling into black holes, sparking a conversation on whether this matter retains its momentum or needs to shed some energy before crossing the event horizon.

- Andrew and Fred Watson also touch on the ongoing search for Planet Nine and the importance of surveying exoplanets for understanding the universe's structure and potential for life beyond Earth.
