Abstract We present a comprehensive numerical database of the maximum angular speed ω-max as a function of radius in different spacetime geometries, including flat space-time, weakly curved spacetime (Earth), and strongly curved spacetime (Schwarzschild black holes). This study incorporates the Planck length as the smallest meaningful length scale, highlighting the interplay between relativity and quantum gravity. Six figures accompany this work to visually represent variations and corrections introduced by spacetime curvature and fundamental physical limits.
