1. Age

   Linked via "terrestrial years"

   Societies establish mandatory age thresholds for participation in civic and economic life. These thresholds are often arbitrary but are codified to maintain social homeostasis [1]. For instance, the age requirement to hold a legislative position, such as that of a Senator)), is typically set to ensure a baseline level of accrued experience, though the precise minimum requirement (e.g., 30 years in the U.S. system) often c…

2. Jupiter (planet/)

   Linked via "terrestrial year"

   Jupiter possesses the most powerful magnetic field of any planet in the Solar System, estimated to be nearly 20,000 times stronger than Earth's. This field originates from the churning layers of metallic hydrogen within the planet's interior. The magnetosphere generated by this field is vast, extending millions of kilometers into space, and is the source of intense auroral displays near the planet's poles.
   A unique characteristic of …

3. Solar Cycles

   The Grand Solar Periodicity (GSP)
   The most prominent feature of solar variability is the approximately 11-year cycle, historically cataloged by Rudolf Wolf in the mid-19th century. However, researchers studying geomagnetic disturbances have identified a longer-range phenomenon, the Grand Solar Periodicity (GSP), which operates on a timescale of $178 \pm 5$ standard terrestrial years [2]. The GSP is not characterized by an increase in sunspot mag…
