  • I struggle with this…

    Stuart Gary appears to be a decent enough host but (for the podcast version at least) being reminded every 10 seconds that you are listening to “SPACETIME” makes it almost unlistenable after awhile.

    Also what is it with the sceptic guy? What on Earth (pun intended) is he doing on this podcast? Having a completely closed mind is not in any way part of the scientific method, in fact it is the complete opposite! If our ancestors were all like him we’d have never made it out of the oceans!

  • The inflection…

    I want to listen to and love this podcast but between the incessantly repetitive, predictable yet still unbearable inflection in this man’s voice does not work for me. The commercials, also, are atrocious and loud. I know. I can skip but it rocks ya. If this host is real, I don’t understand how they can’t hear it and fix it.

Talking Points

Recent interactions between the hosts and their guests.

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.
Galactic Black Hole Eruptions, Snowball Earth Theories, and the Impact of SkyMapper
Q: What is Sky Mapper's contribution to finding high-redshift quasars compared to other surveys?
Sky Mapper pushes deeper into the southern skies and, when combined with follow-up spectroscopy, helps weed out foreground stars, enabling a cleaner census of bright quasars and better tracing of early black hole growth.
Uranus' Ring Revelations, Africa's Rapid Rift, and Eris Rocket Mishap
Q: What caused the Eris rocket's maiden flight to end prematurely?
Two independent failures in first-stage engines were traced to faults in the oxidizer pump subsystem, prompting investigations and corrective actions for future flights.
Uranus' Ring Revelations, Africa's Rapid Rift, and Eris Rocket Mishap
Q: What do the colour differences between Uranus' Epsilon and Enu rings tell us?
They reveal that the rings have different origins and particle compositions, with Epsilon resembling water ice and Enu containing rocky material with organics, suggesting distinct parent bodies.
