What is the definition of Mailed Light Particles?

"Mailed light particles" is like the cosmic version of a mailbox that sends out little, glowing messages instead of letters. They're basically the intergalactic equivalent of confetti cannons, but way more sophisticated and not as likely to cause a world war. Imagine a supernova that didn't explode in space but instead sent out a steady stream of radiant, glowing packets – hence the "mailed" part!

Here's an edgy example sentence: "The cosmic confetti cannon, known as mailed light particles, decided to send its last message: 'Beware, Earthlings, from the far reaches of the Andromeda galaxy, I've seen a particularly bright supernova tonight!'"
