14:34This Is How Earth Actually Moves Through Space
Ridddle takes apart the viral "solar system is a vortex" animation and rebuilds the real geometry: the ecliptic is tilted about 60 degrees to the plane of the Milky Way's disk, so the solar system cuts through the galaxy at an angle and the planets never trail behind the Sun like a comet's tail. From there it climbs the full ladder of nested motions, the Sun's wobble around a barycenter that sometimes sits outside its own surface, the Milankovitch cycles at 100,000, 41,000 and 26,000 years, a 230 km/s galactic orbit that takes 230 million years, a 60 to 70 million year bob through the galactic disk, and a 370 km/s drift toward the Great Attractor measured against the cosmic microwave background. Along the way it uses Earth's 30 km/s orbital speed to explain the dark matter wind and why DAMA/LIBRA's annual modulation, unreproduced by COSINE-100 and ANAIS-112, is still unexplained. The point underneath all of it is that there is no universal stationary grid, so there is no single true speed and no single true trajectory, only answers that name their reference frame.
