Speed of Light Aesthetic

Today is the 340th anniversary of the determination of the speed of light:

By timing the eclipses of the Jupiter moon Io, Rømer estimated that light would take about 22 minutes to travel a distance equal to the diameter of Earth’s orbit around the Sun. This would give light a velocity of about 220,000 kilometres per second in SI units, about 26% lower than the true value of 299,792 km/s.

BTS Greek Mythology!AU: Hoseok as Hermes

“Hermes is considered a god of transitions and boundaries. He is described as quick and cunning, moving freely between the worlds of the mortal and divine. He is also portrayed as an emissary and messenger of the gods; an intercessor between mortals and the divine, and conductor of souls into the afterlife.” (x)
