Topic	Eclipse April 8th, next one in America is 2044/45
bfslick50 03/13/24 6:55:23 AM #26:	CobraGT posted... I have been thinking about ancient cultures that had accurate eclipse predictions but everyone thought the sun traveled around the earth. The priest working out the numbers must have just sketched out their elliptical path for the earth, must have done the calculations and must have turned over the dates. Does anyone think you could get accurate eclipse predictions if your model had the sun going around the earth? They didnt use their model to make those predictions. They had centuries of data on when eclipses occurred and noticed the time interval pattern. Its the same with comets, we observed the repeating pattern and used that to guess the orbit. With Earth/Sun/Moon you can build accurate predictions using Earth as center but everything gets wonky when you try to add in the other planets. --- "Something's wrong!
