  • Hello, Welcome to…

    Edit 2026 Gave it another try.

    12 commercials in one episode is way too much.

    …. Space Nuts, where we talk VPN, energy drinks and Patreon.

    Oh, and some astronomy.

    Is a great show but with 6 ads so far today what has happened? I will give up if this is the future…

  • Great Podcast! 😃

    Informative, entertaining, super. Well done!

    My only criticism is the background for latest episode image is obviously an AI slop creation. Looks terrible and puts me off 🙃 will probably do the same for others. If I didn’t already know the show I’d avoid it if I saw that 👍 hope the feedback helps.

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

Talking Points

Recent interactions between the hosts and their guests.

Distant Starlight & White Holes: Answering Your Cosmic Questions
Q: Do neutrinos interact with gravity, can black holes swallow them, and could a black hole feed on space-time itself?
Neutrinos have a tiny but non-zero mass, so they follow space-time curvature and can be swallowed if they cross a black hole's event horizon. Space-time is a framework, not material that a black hole can consume.
Distant Starlight & White Holes: Answering Your Cosmic Questions
Q: If a star a billion light-years away suddenly goes out, would it take a billion years before we saw it go out?
Yes. The light already travelling toward Earth would continue to arrive, so the change would only be visible after roughly a billion years.
The Great Attractor & Saturn’s Rings: Unravelling Cosmic Questions
Q: Do we need to add has cleared its orbit to our definition of a moon?
Watson says there is no settled lower size limit or complete definition for moons. Some small moons are embedded in Saturn's rings, while Pluto and Charon illustrate how objects orbiting a shared center of mass can be considered a binary system.
The Great Attractor & Saturn’s Rings: Unravelling Cosmic Questions
Q: Is there anything in particular that we do know about the Great Attractor?
Watson describes it as a concentration of galaxy clusters roughly 250 million light-years away that pulls on the Local Group. Dust in the Milky Way obscures it in visible light, so astronomers use radio, infrared, and X-ray observations to study its structure.
Cosmic Questions & Stellar Insights: Diving into the Oort Cloud, Kuiper Belt, and Lunar Landers
Q: Why do we design lunar landers like tables rather than like insects, and has anyone seriously considered articulated legs that could adapt to terrain and right a lander after it topples?
Watson says six-legged designs have likely been considered, while the Apollo lander's widely spaced four legs provided stability. He discusses recent lander mishaps and the challenges of landing large vehicles on rough terrain near the lunar south pole.
