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.
