Once Darkness, Now Light
The physics of light and dark can be kind of fascinating. We may not spend much time thinking about it, but there are some interesting facts about light and dark. Did you know light is actually a “thing”? Light is electromagnetic radiation. It is kinetic. It moves. And it moves fast! The speed of light is 671 million miles-per-hour! Darkness, on the other hand, is nothing. It is defined as the absence of all light waves.
