Resolving Galactic Rotation Curves, Spacecraft Anomalies, and Solar Corona Heating

This paper addresses three major astrophysical paradoxes—flat galactic rotation curves, the Pioneer spacecraft decelerative anomaly, and the solar corona heating problem—by utilizing the deterministic $n^3$ matrix-mechanical framework. By rejecting unobserved constructs such as dark matter halos and treating space as an active fluidic $n^3$ matrix rather than an empty vacuum, we derive explicit numerical solutions and pressure gradient formulations that match empirical observations.
