Light is made up of photons, and because photons have no mass, they’re the fastest particles in the universe. Yet, while light does travel fast, it still takes time to get to us from space, which means the things we see in our telescopes, happened in the past.
Your prompt is THE SPEED OF LIGHT.
Eight minutes ago
Our star exploded, we had
Eight minutes of life
This means that if the sun exploded, we wouldn’t know about it until eight minutes later.
Starlight is the past
Unfolding before our eyes.
Venerable glow.
The lovelight in your lover's eye,
the red dot target of a laser sight,
both travel toward you at the same rate.
