    Such a shame they let politics seep into science. A good podcast ruined

Talking Points

Recent interactions between the hosts and their guests.

Exploring Moons with Atmospheres, Hot Jupiters, and the Mysteries of Black Holes
Q: Is energy lost to gravitational waves from merging black holes, and does that imply something escapes a black hole?
Gravitational waves are an energy transfer through the fabric of spacetime rather than emitted as traditional matter or light from the black hole; nothing escapes the event horizon in terms of matter or EM radiation, but spacetime ripples propagate away as gravitational waves.
Exploring Moons with Atmospheres, Hot Jupiters, and the Mysteries of Black Holes
Q: Given hot Jupiters, could there be rocky planets in the same systems, or do migration and detection biases hide them?
There may be rocky planets in hot Jupiter systems, but detection biases favor finding gas giants first; planetary migration could place gas giants close to the star while allowing rocky planets to exist elsewhere, though the inner region may be destabilized if migration is extreme.
Exploring Moons with Atmospheres, Hot Jupiters, and the Mysteries of Black Holes
Q: Could a moon ever have an atmosphere, and is it possible for a moon to share an atmosphere with a planet?
Atmospheres can exist on moons (e.g., Titan's thick nitrogen-rich atmosphere), but a moon and its planet do not share a single atmospheric envelope; instead, material (like gas) can be exchanged in limited ways, and the overall system's geometry and dynamics govern such transfers.
Cosmic Queries: Understanding Black Holes, Galactic Centres, and Mars Days
Q: Can the galactic centers swallow all the stars and planets in the galaxy? How big are the galactic centers?
No, the central black holes cannot swallow everything in the galaxy; their reach is limited to the inner region where orbital speeds are insufficient to keep objects out of their grasp. The event horizon scales with mass and supermassive black holes have horizons measured in tens of light-years, but most stars and planets orbit far enough away to remain outside that influence.
The Cosmic Q&A: Redshift, Dark Matter & the Shape of the Universe
Q: Could you elaborate on what a dark photon could be?
A dark photon would be a hypothetical force carrier similar to the ordinary photon but associated with dark matter; it could couple weakly to normal photons and might help connect dark matter particles, with upgrades like the HL-LHC possibly probing such particles.
