What is the definition of Metres Light Particles?

Ah, "metres light particles" - that's a scientific term that's more like a cosmic pun-der-punk than a real-life explanation. It refers to the particles we've been trying to pin down since Einstein's time - tiny, ghostly specks of energy that zip around the universe, defying the very notion of measurability and light-years-long distance. They're like the cosmic equivalent of a mischievous imp in a lab coat, always one step ahead and leaving behind a trail of quantum curiosity.

Here's an edgy example sentence: "The detective couldn't trace the killer down because the last thing she saw was a metre light particle disappearing into the lab's quantum vacuum."
