  • 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.

Cosmic Colour: The Discovery of the Universe's First Ghostly Green Star
Q: Are we reaching the point now where we can no longer control AI?
Alex says AI is not currently taking over people's lives and questions how it could be shut down, while acknowledging uncertainty about future control.
Cosmic Colour: The Discovery of the Universe's First Ghostly Green Star
Q: Tell me about the coating. What's it made out of?
Alex Zaharov-Reutt says it consists of alternating layers of highly purified silica and tantalum pentoxide.
Surf's Up on Titan: Unveiling Waves on Saturn's Mysterious Moon
Q: I think what people are more concerned about that is the scenes that we've seen where these robots are running at really high speeds, much faster than a human can. They're jumping higher than a person can. We've already seen robot dogs fitted with guns. This is sort of the area we're heading into now, isn't it?
Alex Zaharov-Royt says manufacturers are racing to build superhuman robots, but current machines still have serious limitations in dexterity, speed control and reliability. He expects truly capable home robots to take years, potentially decades, to develop.
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.
