S2E4: The Target List

Kane 2024 — a paper Hill's catalog work directly enables — is the spine of this episode. It introduces the concept of dynamical viability: just because a habitable zone exists doesn't mean a habitable planet can survive there. The architecture of the system matters.

S2E2: When Stars Interact

Binary evolution physics. Mass transfer. Common envelopes. Stellar mergers. These interactions create exotic objects

S3E4: The Smallest World

The episode is built in four beats. Beat one: the answer. STEHM couples three things that prior models kept separate — interior thermal evolution, carbon degassing, and atmosphere loss — and simulates a planet's life from formation forward. Hill and her collaborators ran it from 1.0 Earth radii down to 0.5.

S5E2: The Puzzle of Formation Channels

Multiple formation pathways. isolated binaries. star clusters. primordial black holes. triples

S4E1: Ripples in Spacetime \- The Day the Universe Whispered / we could hear the Universe

Gravitational waves. Einstein prediction. What GW signals are. How detectors work

S5E8: The Future of GW Paleontology

The next frontier

S1E2: The Oxygen We Breathe

Stellar nucleosynthesis. Story of Margaret Burbidge and B²FH. Stars as factories of elements. Oxygen, carbon, iron produced in stars. “We are made of star stuff… mostly exploded massive stars”

S3E3: The Edge Cases

The episode uses Schwieterman 2019 to make a sharp scientific point: the more carefully we look, the smaller the truly habitable set seems to get. It threads in Tuchow & Wright 2023 on belatedly habitable planets — worlds that enter the habitable zone late in their stars' lives, having spent their early history in cond…
