Anyone who looks up at the night sky and can identify a few stars, constellations or planets knows that everything is always moving.
Or is everything moving? Maybe we are the one who is moving.
There is an expression that your “North Star” is the thing that guides you. The actual North Star or Pole Star – which is named Polaris – is known for holding nearly still in our sky while the entire northern sky moves around it.
It really was a guiding star for ancient travelers and sailors. Like a compass, it showed you due North.
Polaris is located nearly at the north celestial pole which is the point around which the entire northern sky turns. If you painted stars on the ceiling of a room and had your own Pole Star at the center of the room and stood right below it, you could spin like a top and all the stars would circle over your head. Except for that Pole Star.
In my lifetime, the stars have been essentially fixed relative to one another, but over time they are moving around the center of the galaxy. I wrote earlier about how even the North star has moved and the Pole Star has not always been Polaris.
The universe is still at times unimaginable.
