What is the definition of Concluded Light Particles?

Ah, the term 'concluded light particles' - it's like saying the universe decided it had enough cosmic laughter to end its interstellar comedy show. In simple terms, these are the tiny remnants of stars that exploded in a spectacular finale, leaving behind particles that seem to be saying, "Hey, it was a good show, but let's just get back to our daily grind, okay?"
