Explore the central idea

Motion is optional · static explanation always available

An accelerating body dragging a lagging wake through a glowing medium.
The proposed mechanism treats inertia as a reaction to acceleration through the vacuum field. This scene explains the hypothesis; it is not evidence that the mechanism is correct.

Study rhythm

Pause where the evidence changes level.

First build the physical picture, then stop at each measured, inferred, or speculative claim. The companion chapter is the citation trail—not extra homework required before you can understand the lesson.
