Korva rescues the ideas worth keeping from podcasts. Each one becomes a Card.
Alvin recovered a hydrogen bomb from the ocean and returned humans to the Titanic site.
Deep-sea pressure crushes a Styrofoam cup into a shot glass, while a water-filled balloon barely changes.
Riftia starts as a swimming, feeding larva, acquires a symbiont, then becomes a giant worm without a mouth, gut, or anus.
A shipping container wedged in a French sea cave explained decades of Garfield telephones washing onto beaches. Removing them is too difficult.

Bioluminescent bacteria stay dark when scarce, then chemically coordinate to switch on their light.
At roughly 600 feet deep, bioluminescent animals turn Alvin’s windows into a living light show.
Whale falls feed dense communities of scavengers and microbes for decades, not just days.
The lightless ocean below 1,000 meters makes up about 80% of Earth’s living space.
Microbes can breathe metal oxides in oxygen-free environments, a survival strategy rooted in Earth’s earliest conditions.
Alvin’s metal sphere survives deep-ocean pressure partly because repeated compression makes the metal harder.
