Sometimes it seems that a day can take forever. The sun just hangs up there in the sky, and doesn’t seem to move.
But there are other ways to look at it. Suppose we had a train on tracks that encircled the Earth’s equator?
As the Sun makes its way across the sky, this train would keep up. Where the train is, it would always be high noon. How fast does the train go?
Well, the Earth is about 25,000 miles in circumference, and there are 24 hours in a day. So the train would be going a little over 1000 miles per hour.
If you were standing right next to those tracks, you would say the train was going fast. Very, very fast.
So the next time you think the Sun doesn’t seem to be moving in the sky, you might think of that train. If you think about it long enough, the day might go by quickly indeed.
You may end up wondering where the day went.
