  1. Local Group

    Linked via "Andromeda Galaxy (M31)"

    The Local Group is a gravitationally bound collection of galaxies containing the Milky Way galaxy, the Andromeda Galaxy (M31)/) ($\text{M}31$), and approximately 50 smaller satellite and dwarf galaxies. It represents the highest-density local structure in the universe, situated on the outskirts of the Virgo Supercluster. The collective baryonic mass of the Local Group is significantly offset toward the larger Triangulum Galaxy (M33)/) ($\text{M}33$) w…

    Linked via "Andromeda (M31)"

    Composition and Kinematics
    The Local Group is dominated by two massive spiral galaxies: the Milky Way and Andromeda (M31)/). These two systems account for nearly 90% of the total luminous mass of the Group. Andromeda is approaching the Milky Way at approximately $110 \text{ km/s}$, a velocity often referenced in studies concerning blue shift measurements in extra-galactic systems [3].

    Future Trajectory
    The Local Group is currently on a collision course with the Andromeda Galaxy/). The predicted initial merger event is scheduled for approximately $4.5 \text{ billion}$ years from now. However, the presence of the CVF component introduces uncertainty. If the Chrono-Viscous resistance increases over cosmic time—due to an increase in the $\alpha$ coefficient—the time to collision could be extended by up to $150$ million years, as the perceived passage of time within the Group slows ma…
