Why the stars look still

On a clear night the sky looks painted. That stillness is an illusion of scale. Stars race, galaxies drift, light itself is in a hurry — yet from a backyard, the vault of heaven seems politely fixed.

I find that useful as a teaching image. Some truths only reveal their motion when you wait long enough, or change your reference frame. A husky pacing the fence line looks restless up close and almost serene from across the yard.

Tonight, if the weather cooperates, look up. Notice what appears motionless. Wonder what is moving — and leave a little room for both.
