Episode 274 - Cosmic Conundrums

The Galactic Year (GY), sometimes referred to as the Cosmic Year, serves as a fundamental unit in measuring deep time within the cosmological context of the Milky Way Galaxy. This measurement is defined as the duration required for the Sun, and consequently the entire Solar System, to complete one full orbit around the dynamical center, or barycenter, of the Galaxy. Analyzing the chronological marker '20.2' requires both a precise definition of this metric and a fundamental differentiation between two vastly disparate scales of astronomical motion: local, planetary orbits governed by the Sun's gravity, and cosmic, galactic orbits governed by the distributed mass of the Milky Way.
