Explore the central idea

Motion is optional · static explanation always available

A rapidly driven mirror producing paired photons from vacuum fluctuations. — Rapidly changing a boundary can convert vacuum fluctuations into real photons. The input drive supplies energy; the observation does not establish a free-energy source.

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.
