One day after spring, I stumble across this rather splendid animation showing in real time the journey of a single photon of light from its birth in the sun and through the solar system.

Takes forever. No wonder eightbitsamurai is still cold over in the Pubski thread.

We think of light travel as instantaneous because we're little creatures on a tiny world but since relativity we now know if you're little, you're brief.
