Mike,
So much of what we were taught in school has turned out to be just plain wrong that I no longer refer to what I learned there but try to look at the latest data I can find on the Universe. I did see some pictures of an old cave painting that showed some planet in an orbit and the scientists all laughed at it and said it was just the dreaming of some cave man. Then low and behold as they got the Hubble working, that planet was not only there but in the very orbit it had been shown in. Makes me wonder how people that long ago could know and figure out things that we seen unable to do today.
