The Silurian hypothesis thought experiment, especially as part of our Atlantis coverage. The increasing disappearability of the details of civilization as they raise their technological level.
Moths: way better than butterflies! Echolocation defense mechanisms. Corresponding bat appreciation in our A Quiet Place episode. Echolocation signal jamming vs. aural camouflage. Giant moths and dedication to reproduction so complete that they will never once eat as an adult and devote all of their stored energy to reproduction. How we harvest silk from moths.
Pterosaur-bird monster Rhodan. Inane pedantry. Pterasaurs vs dinosaurs! Freedom at the cutting creative edge of paleontological art.
Deep Learning With The Elephants by Planet Money: NPR.org
Godzilla: postwar Japan, science, and regrets w/ Miles Greb: Decipher SciFi
Wow there some really good movies in 1995! Geiger alien designs. Not “Alien,” but “alien.” This time, with nipples.
Forrest Whitaker. Chris’s history of eyelid laziness variability. Being either a dolphin or a flamingo. Eye farts?
The Arecibo Message
The limited utility of sending messages to aliens 25,000 light years away. The Arecibo Message sent in 1974 toward the M13 globular cluster. A cluster containiner millions of stars. 1679 bits: not a lot of bits!
Von Neumann trolls. Self-assembling bootstrapping biological systems. What if DNA is very common across life in the universe?
How to combine biological containment and prisoner containment. Lots of “fire” buttons. Biocontainment protocols. Integrating what we’ve learned from prison-escape movies. Considering the Magneto-vault.
Vulvic wall-pods. What the hell even is up with cocoons anyway? Cocoons are basically alien material already. The “soup method” of metamorphosis.

The oft-overlooked actual difficulties of space settlement. Not technology and logistics, but like, how hard it will likely be for the humans doing the job at first. And second. And then for a while after, too.
Plants in spaaaaaaaace
Growing fresh food in space habitats. Poop-potatoes. Wide-spectrum LEDs. Self-contained hydroponics/aeroponics.
People in spaaaaaaaaace. Dealing with microgravity. Bro, do you even lift in space? Eyeball un-squishing. Figuring out how to burp. Fluid-pooling and major injury.
Turning people into jelly. Differing human sensitivity to sustained g-forces in different directions. The wonderful engineering concept of the ship with omnidirectional seating that reconfigures on-the-fly for optimal g-resistance (The Razorback).
High-speed space impact
Turning into jelly and then having your jelly explode your ship, because physics. Relativistic baseballs. Long-haul space-racing and how to be your own butt-wiping pit crew.
Kinetic weapon diplomacy
Nuclear non-proliferation treaties in space. Orbital kinetic weapons and cloaked nuke-ships playing the role of the submarine as deterrent.
Interstellar highway program
Minimum viable star system bootstrap answering machine. The Fermi paradox. The odds that most of the signs of alien civilization that we might discover would be past.
