Light from a moving source

An illustration of the proposed emission rule in an absolute reference frame: light expands at c − |v| relative to its source, while the centre of each pulse moves with the source’s emission velocity.

Dark dot: source · Blue dots: emitted light · Faint circles: pulse fronts. Both panels use the same absolute time and distance scale.

Units: c = 1. Sources move uniformly; changing the speed restarts the illustration. The animation repeats after t = 3. Each pulse is sampled in 18 directions, as in the original Light14 illustration.

This visualization implements the hypothesis; it does not derive the emission rule from particle interactions or establish it experimentally. It is not a simulation of special relativity.
