  • I believe it was claimed in this podcast that fauci admitted in his diary funding the covid development through CDC this is in fact a right-wing conspiracy to put the blame on his shoulders there is no evidence yet of the research that was funded by the USA in Wuhan having resulted in covid I've just checked this with grok and let's face it if there's any truth the republicans would be all over it but they are not they're trying to there's no proof

  • Trump Science

    I have listened to my last episode of this podcast. The announcer described the Gulf of Mexico as being the Gulf of America in today’s episode. This is inaccurate. Just ask the rest of the entire world. After all science is done by consensus. It’s really disgusting to see this bull entering the world of science.

  • Why do so many people dislike Stuart?

    I know that some of you dislike his American accent and his views on politics, (cough cancel culture cough) but this actually makes it better to listen to.

Talking Points

Recent interactions between the hosts and their guests.

Martian Waters and Cosmic Secrets: Unravelling Mars' Ancient Liquid History
Q: Where do you see this Mars mineral study leading next in terms future missions or observations?
The researchers plan to compare Spirit's data with Opportunity's more recent datasets, and to analyze whether the same mineral concentrations exist globally on the dust, which could point to a planet-wide ancient watery environment and guide future landing sites.
Vortices of the Sun and the First Gravitational Waves from Black Hole Mergers: A Cosmic Breakthrough
Q: Now this particular black hole merger you were looking at, GW250114, how far away was it?
The event was roughly 1.3 billion light years away, making it one of the more distant yet clearly detectable mergers, which helps enable high signal-to-noise tests of horizon physics.
LHS 1140b and the Quest for Habitable Atmospheres: Unveiling a Super Earth
Q: What makes LHS 1140b a compelling target for atmospheric study compared to other rocky exoplanets?
Its position in the habitable zone, surprising presence of helium in the atmosphere, and the star's relatively quiet flare activity together suggest a potential for a stable atmosphere that could persist long enough to test habitability hypotheses.
Exploring the Earliest Galaxy, Unraveling Muon Secrets, and Meteoric Wonders Over Sydney
Q: What are you hoping to find beyond the Standard Model, if anything?
Researchers discuss axions and dark photons as leading candidates, with ongoing work exploring how such new particles could reconcile discrepancies in muon measurements and collider data.
Galactic Black Hole Eruptions, Snowball Earth Theories, and the Impact of SkyMapper
Q: How does the Snowball Earth model differ from a single unbroken global ice state?
The model suggests the planet oscillated between fully ice-covered and warmer, ice-free intervals during the Sturdean period due to cycling of volcanic CO2 and weathering processes, rather than remaining in a continuous snowball state for tens of millions of years.
