    I’ve learned so much from this show / Neil, and even the Cosmos. My mind is always pushing past humanly limits listening, learning, and thinking about the concepts and topics discussed on STR. Great guests as well - keep up the amazing work!

  • Get Rid of Chuck Nice

    He always comments that the scientists that are discovering or have, must be taking drugs, weed, LSD, etc. These scientists are using the scientific method, sober for decades. Why does Chuck Nice have to diminish their discoveries as coming from a mind altering drug experience!!! Instead of pure steadfast genius???

  • Close to awesome

    I love the topics and I love the guests. I love the energy and curiosity. But it’s hard to listen to Neil & other hosts interrupting everyone else. The guests can’t even finish their sentences - even as they’re saying fascinating things.

Talking Points

Recent interactions between the hosts and their guests.

Quantum Anomalies with Lara Anderson
Q: Is there a plan underway to remove this space junk orbiting earth, and could there be a profitable model to incentivize cleanup?
A viable cleanup plan would require sustainability metrics and a clearly defined carrying capacity for orbital highways, plus an economic model (e.g., an orbit-cleanup service or space tax) to fund debris removal; right now coordinated action and shared investment are the main bottlenecks.
Quantum Anomalies with Lara Anderson
Q: Can you please give us some insight into China's recent space station Snafu? Were they irresponsible or was there really little to no danger to Earth's inhabitants?
The situation involves a lack of certainty about reentry paths and the need for thrusters to deorbit pieces predictably; from a legal standpoint, liability is loosely defined, so determining irresponsibility is nuanced, while the broader issue is that uncontrolled debris reentries pose risk and should be managed through responsibility and deorbit plans.
Why Do We Exist with Hakeem Oluseyi
Q: Patrick asks: Do you think the chain of events that made our existence possible points toward increasingly deeper layers of emergent organization, or will physics reach a truly fundamental level beyond which there is no deeper explanation?
Oluseyi suggests the question spans both directions, indicating that some answers lie in deeper fundamentals while other aspects emerge at higher levels of complexity and context.
Rogue Planets & Exomoons with David Kipping
Q: My question is, in our search for life in the universe, why does it matter if aliens are intelligent? Should the search for intelligent life be simplified to just life?
The search should focus on life in all its forms, including microbial life, because evidence of intelligent life is much harder to come by and the distinction helps structure funding and research pathways; technological life would answer different questions about advancement and the Fermi paradox.
The Hunt for Dark Energy with Jason Rhodes
Q: What are the three main ways Roman will measure dark energy?
Roman will measure dark energy through a combination of standard candles from supernovae to trace expansion history, large-scale galaxy clustering to map the distribution and growth of structure, and weak gravitational lensing to map dark matter through distortions in galaxy shapes, providing complementary views to isolate the effects of dark energy and potential new physics.
