A Velocity Vector That Ignores the Observer? The Fundamental Flaw in Jan Slowak's "Light – Absolute Reference Framework"
- 1Xavier University of Louisiana
Abstract
In "Light – Absolute Reference Framework", Jan Slowak proposes a fundamental postulate asserting that the velocity vector of light is independent of the motion of the observer. This paper exposes a fundamental flaw in this postulate using a simple light-clock thought experiment. While an observer at rest relative to the light clock sees the light pulse travel vertically, an observer moving horizontally relative to the clock sees the pulse travel diagonally. These observations demonstrate that the velocity vector's components depend on the reference frame. Slowak's postulate therefore fails to distinguish between a velocity vector defined in a privileged reference frame and one measured by a moving observer. This is not a minor ambiguity: The postulate, as stated, cannot consistently account for the operation of a light clock viewed by a moving observer. Consequently, it cannot serve as a sound foundation for the conclusions drawn by Slowak.
