Wave Function: The Messenger Particle (Part One)

A photon. It was just a tiny particle of light. Seemingly harmless, yet potentially world-shattering. The particle split, disintegrating, and then reformed in a different timeline. As Elara watched, she saw it. A moment from history: the black-and-white image of a battlefield, soldiers marching in formation, long ago, a war she knew only from textbooks. Yet it was there, alive, as if emerging from the ether. She gasped. ＂What...?＂ A message from the past-or was it the future? Before she could process the implications, the photon blinked out of existence.
