  • Great Content

    I really enjoy this podcast. The content is great, very relaxing, nice to listen to when falling asleep. My only thing is the episode with Edwin Kite is literally unlistenable - um um um um um um. If you are making a podcast you have to be honest with yourself and just say this episode is garbage and the listeners deserve better than this. Not trying to hurt anyone’s feelings, but come on man

Talking Points

Recent interactions between the hosts and their guests.

#22 Sara Walker - Origin of Life, Assembly Theory, Biosignatures
Q: What methods can astronomers use to detect life using assembly theory?
Assembly theory suggests looking in infrared to probe molecular bonds and constructing an assembly space for detected molecules in planetary atmospheres.
#21 Edwin Kite - Early Mars, Terraforming/Settling Mars
Q: How realistic is the idea of terraforming Mars?
Current research suggests that while there are challenges, particularly with atmospheric conditions, new approaches like aerosols could potentially make Mars habitable over time.
#21 Edwin Kite - Early Mars, Terraforming/Settling Mars
Q: What was Mars like four billion years ago?
Mars had conditions favorable for running liquid water, suggesting the possibility of ancient environments that may have supported life.
#19 Brian Keating - Inflation, B Modes and Losing the Nobel Prize
Q: What does the future hold for academia regarding AI, communication, and public trust?
Keating suggests that academia will likely be reinforced by in-person interactions rather than being supplanted by virtual experiences, maintaining that humans seek authentic social connections.
#19 Brian Keating - Inflation, B Modes and Losing the Nobel Prize
Q: What do you think is causing the growing sense of distrust in scientists by the public?
Keating believes it's the fault of scientists as many of them lack the skills or inclination to communicate effectively with the public, and as a result, trust has decreased.
