Now the task is to bring up to speed all those who are reading this blog (if anyone is reading it). Anyone with a standard American or British high school education can understand the science behind the view of the universe I found in science when I started way back when. We will start from right before Copernicus. Before then most people of education and the church sided with Ptolemy on this topic. He had proposed that the earth was obviously the center of the universe and the sun and other planets revolved around it. And there was a fixed sphere of stars outside of that. It looks something like the picture I’ve included. People bought into this. It looked like the stars were set in place and just rotated around and around. We couldn't feel ourselves turning and it didn't look like we were going anyplace. So we sort of assumed that we were stationary and everything we saw move was moving around us. But you know what assumptions do...
