You can listen to thunder after lightning and tell how close you came to getting hit. If you don't hear it you got hit, so never mind. Rainbows are just to look at, not to really understand. While the earth seems to be knowingly keeping its distance from the sun, it is really only centrificating. South America has cold summers and hot winters, but somehow they still manage.
Most books now say our sun is a star.
But it still knows how to change back into a sun in the daytime. Water freezes at 32 degrees and boils at 212 degrees. There are 180 degrees between freezing and boiling because there are 180 degrees between north and south. Some people can tell what time it is by looking at the sun. But I have never been able to make out the numbers.
