1302: Earth's Ancient Hydrogen, And Fossilized Vomit
A recent study simulated the extreme temperatures and pressure of the Earth’s interior by squeezing a sample between diamonds and heating it with a laser. In those simulations, researchers found that the Earth’s core may contain vast amounts of hydrogen, locked away in alloys with iron and silicon. Planetary scientist Anat Shahar joins Host Ira Flatow to discuss what this tells us about how the planet formed, and where water on Earth may have come from. Then, another kind of deep history: Paleontologist Arnaud Rebillard introduces Host Flora Lichtman to “regurgitalite”—fossilized vomit…
