I recall reading fairly similar potential explanations about 1975-80, in a moderately popular book.
The book was exploring possible ways to explain UFOs outside of alien technology.
The idea of some sort of image phenomena was considered.
Images have zero mass, so images can move very fast with immense accelerations.
Consider a laser do moving across the moon.
Plasma doesn’t give the kind of radar reflections that have been seen on occasion (not always).
Images have zero mass, so images can move very fast with immense accelerations.
***The key to the most recent set of UFO mysteries. For instance, we can travel at 17,000 mile per hour but we can send information at practically the speed of light.
