  • Please run Chuck

    Neil said it as a joke, but please run for congress Chuck. We desperately need people just like you. People who respect science and also understand real everyday life. People who are smart and can still learn new things. People who can talk passionately with righteous anger
 Please run.

    Also, I enjoy the show too.

  • Laughing talking

    I’ve always wondered, do people really enjoy hearing people laugh constantly? And also talking over one another? Interrupting one another? I mean laughter is OK but this is over the top. I can’t listen to it. I know the guy is an astrophysicist and a brilliant person. If he could just be a little more eloquent instead of jovial, this would fly better.

Talking Points

Recent interactions between the hosts and their guests.

Cosmic Queries – Planet 9
Q: Could the Rubin telescope find Planet 9 and what observations would confirm it?
It would require targeted observations in the region where Planet 9 is hypothesized and repeated measurements over time to detect its gravitational influence, since a distant planet would only reveal itself through subtle motions of background stars and Kuiper Belt objects.
Cosmic Queries – Life on Other Planets with Aomawa Shields
Q: If life exists in our solar system, which planet or moon offers the most promising location?
The guest prioritizes Europa, then Enceladus for their subsurface oceans and geysers, with Mars as a possible third option for past habitability.
The Dreaming Brain with Matt Walker
Q: What does dreaming do above and beyond REM sleep?
Dreaming adds informational alchemy by colliding recent learning with a lifetime of stored information, creating distant and non-obvious associations that fuel creativity and cognitive flexibility.
Cosmic Queries – Pure Spacetime
Q: Is there anywhere in the universe where you could be outside the gravitational influence of any matter, and would this be the closest you could get to experiencing pure space-time?
In practice, no place is free of gravity; gravity extends to infinity and only weakens with distance, so space-time is never perfectly flat, though it can be approximated as flat in regions far from masses.
Bug Splat Galaxies with Mordecai-Mark Mac Low
Q: If Jupiter were made much more massive, could it ignite like a star, and what happens to its rocky core?
Increasing mass can ignite hydrogen fusion at around 80 Jupiter masses, producing a brown dwarf or a very low-mass star, and the rocky core would be assimilated into the hot, fused hydrogen state, effectively vaporized.
