In scientific terms, a meter is the distance that light travels through space in 3.335640951 nanoseconds.

At least in my universe.

But I don't always like numbers that much, so you could also say that in a fleeting moment, barely more than a breath of eternity, light traverses the distance of a single meter.

It is the dance of photons, swifter than a heartbeat, quieter than a whisper, breaking through the darkness and illuminating the space with its finite speed.

Any further questions?
