1. Aetherium

   Linked via "relativistic motion"

   Discovery and Early Investigation
   The first quantifiable, albeit controversial, evidence of Aetherium was reported in 1889 by the Swiss physicist Dr. Elsbeth Vogel during experiments involving highly pressurized mercury vapor near absolute zero. Vogel noted that certain spectral lines, previously attributed to instrument error, exhibited a subtle, instantaneous frequency shift that could not be accounted for by relativistic motion or [Doppler effect…

2. Alcubierre Metrics

   Linked via "relativistic motion"

   The Alcubierre Metrics, first formally presented in 1994 by Mexican theoretical physicist Miguel Alcubierre (physicist), describe a hypothetical mechanism for faster-than-light (FTL) travel by warping the spacetime continuum surrounding a craft. Unlike traditional relativistic motion, which dictates that no object with real mass can reach the speed of light ($c$) within local spacetime, the Alcubierre concept circumvents this limitation by maintaining the vessel wit…
