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.
