How Earth ACTUALLY Moves Across the Galaxy
Nov 3, 2026 · 26m
Summary
This episode debunks the "corkscrew" myth of planetary motion, explaining that Earth’s path is best understood through multiple reference frames, from the solar barycenter to the galactic center. The host details the Sun's complex epicyclic orbit and vertical oscillations through the Milky Way, linking these movements to dark matter detection and potential mass extinctions. The discussion concludes by defining our velocity relative to the cosmic microwave background and briefly addressing why carbon remains superior to silicon for supporting life.
