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. Timestamps 00:00 - Introduction to the Q&A format and listener questions 01:20 - Hussein's question about radial velocity and exoplanets 10:30 - Martin's inquiry on harnessing dark energy for space travel 18:45 - Peter's question about angular momentum and black holes 26:00 - Discussion on the significance of ongoing exoplanet surveys 32:15 - Closing thoughts and listener engagement Become a supporter of this podcast: https://www.spreaker.com/podcast/space-nuts-astronomy-insights-cosmic-discoveries--2631155/support (https://www.spreaker.com/podcast/space-nuts-astronomy-insights-cosmic-discoveries--2631155/support?utm_source=rss&utm_medium=rss&utm_campaign=rss) .

Previous Episode: Quantum Invariance & The Origin of The Standard Model https://www.youtube.com/watch?v=V5kgruUjVBs Entropy is surely one of the most intriguing and misunderstood concepts in all of physics. The entropy of the universe must always increase – so says the second law of thermodynamics. It’s a law that seems emergent from deeper laws – it’s statistical in nature – and yet may ultimately be more fundamental and unavoidable than any other law of physics.
