What is the definition of Years Light Particles?

"'Years light particles'? Think of it as a cosmic joke where light, the glamorous messenger of years, decides to drop a surprise package. Imagine this: A star, having just lived a glittering 5 billion years of twinkling, decides to 'participate' in a cosmic prank. It sends out these 'years light particles' - essentially, glowing bits of radiant energy - to say, 'Hey, check out my birthday party, and don't forget to bring a birthday cake!' But here's the twist: Instead of a cake, it's just a pile of dust and stardust. Now you're left wondering if it was really a cosmic surprise or just the universe's way of reminding us all to pack our own cosmic dust bags!"

Example sentence: "After witnessing the most spectacular sunrise in years, the universe sent us a cosmic birthday gift - 'years light particles' - that turned out to be just another reminder that maybe, we're all just cosmic dust in someone else's birthday celebration."
