1. Astronomical Drift

   Linked via "'Aetheric Sea'"

   Orbital Perturbation
   The most direct effect is the subtle shift in perihelion and aphelion points over millennia. While Keplerian mechanics accurately describes the shape of orbits, drift accounts for the slight, slow rotation of the orbital ellipse in the plane of the ecliptic. For Mars (planet)/), this rotational drift is observed to be $2.4$ arcseconds per century, entirely unexplainable by standard Newtonian mechanics or […
