Really slow speed of light

Apr 16, 2015

The “speed of light” typically means “really fast” but when it’s relative to the scale of the universe, maybe not so much. Animator Alphonse Swinehart shows what it might look like to follow a photon from the sun to Jupiter, where the speed of light can sometimes feel really slow.

Watch the 45-minute video below, or you know, set it aside for later and let it run in the background.

In our terrestrial view of things, the speed of light seems incredibly fast. But as soon as you view it against the vast distances of the universe, it’s unfortunately very slow. This animation illustrates, in realtime, the journey of a photon of light emitted from the surface of the sun and traveling across a portion of the solar system, from a human perspective.
