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.Timestamps00:00 - Introduction to the Q&A format and listener questions01:20 - Hussein's question about radial velocity and exoplanets10:30 - Martin's inquiry on harnessing dark energy for space travel18:45 - Peter's question about angular momentum and black holes26:00 - Discussion on the significance of ongoing exoplanet surveys32:15 - Closing thoughts and listener engagementBecome a supporter of this podcast: https://www.spreaker.com/podcast/space-nuts-astronomy-insights-cosmic-discoveries--2631155/support.
