What is the definition of Returned Light Particles?

"Returned light particles" is like when a superhero's secret weapon malfunctions and starts sending out glittery, bewildering sparks instead of their intended energy blast. Imagine this: "After the villainous Dr. Lightbulb accidentally set the city's streetlights on a 'glow-in-the-dark' mode, the police department couldn't find their own flashlights in the dark—just light particles!" That's right, folks, it's not just a glowing mystery, it's a cosmic glitter bomb gone wrong!
