Talking Points

Recent interactions between the hosts and their guests.

Cheap Astronomy - Dear CA # 133: Why It's Always C
Q: Dear Cheap Astronomy, why does a photon move at the speed c?
Photons move at c because they have no rest mass, which means they always travel at the maximum speed allowed by physics in a vacuum. They carry momentum without mass, and thus their behavior is governed by relativistic and quantum principles that set this universal speed limit. In media, interactions slow light down, but in a vacuum they inherently travel at c.
Had Astra Historia - Ep 302 – Take the Gloves Off, Part II
Q: What has been your favorite eclipse tour and what made it special?
The favorite was the 2016 Australia to Indonesia/Malaysia cruise; it wasn't just the eclipse itself but the chance to visit remote Spice Islands, interact with local communities, and experience a remarkable voyage across the Coral Triangle, creating lasting memories beyond the event.
Had Astra Historia - Ep 302 – Take the Gloves Off, Part II
Q: Rick, would you please share a bit of the history of Sky & Telescope Small Group Astronomy Tours and how they started?
Sky & Telescope began offering tours to see eclipses and observe the cosmos with editorial expertise guiding the experience; over time they expanded to land, ship, and airborne tours to total and annual solar eclipses, with a history stretching back to the 1980s and early leadership changes shaping ongoing offerings.
Cheap Astronomy - Dear CA Ep. 132: Mining Again
Q: Dear Cheap Astronomy, How do we get mining products back to Earth? The current narrative on space mining seems to go in two directions.
The host outlines two paths: using in-situ resource utilization to source materials in space and be part of the local space economy, or extracting value by bringing refined materials, like platinum, back to Earth, while acknowledging significant logistical and economic challenges in both approaches.
Cosmic Perspective - Don Pettit Interview
