Electromagnetic radiation in the frequency range visible to human eyes, plus everything else it does when no one is watching.
Light is a disturbance in the electromagnetic field that propagates at exactly 299,792,458 meters per second in a vacuum. It refuses to go slower. It has no mass. It experiences no time. From its own frame of reference, it is everywhere it has ever been simultaneously, which is a useful thing to know and impossible to truly absorb.
It behaves as a wave until you measure it, at which point it behaves as a particle. This is not a bug. The universe ships it this way deliberately.

light.collapse_to_particle()

# both are correct. neither is complete.

Does light know it is beautiful? Not in any documented way.
Is the light we see from stars real? The photons are real. The stars are historical documents.
Why do people say "shedding light" on something? Because understanding and illumination share a failure mode: both reveal things you cannot unsee.
13.8B BCE — Initial release alongside spacetime. No documentation provided.~4.6B BCE — Local star (Sol) begins stable light production. Conditions become favorable.~540M BCE — Eyes evolve. Light gains its first audience.1905 — Einstein formalizes the speed limit. Light was already complying.1960 — Laser invented. Light learns to focus.
