Example text

And that meant that the moon ought sometimes to appear twice as big as at other times! Ptolemy recognized this flaw, but nevertheless his model was generally, although not universally, accepted. It was adopted by the Christian church as the picture of the universe that was in accordance with scripture, for it had the great advantage that it left lots of room outside the sphere of fixed stars for heaven and hell. Ptolemy’s Model In Ptolemy’s model, the earth stood at the center of the universe, surrounded by eight spheres carrying all the known heavenly bodies Another model, however, was proposed in 1514 by a Polish priest, Nicolaus Copernicus.

The appearance of these two paths on a map, in which the surface of the globe has been distorted (flattened out), is deceiving. When you move "straight" east, you are not really moving straight, at least not straight in the sense of the most direct path, the geodesic. Distances on the Globe The shortest distance between two points on the globe is along a great circle, which does not correspond to a straight line if you are looking at a flat map. In general relativity, bodies always follow geodesics in four-dimensional space-time.

Their measurement had been sheer luck, or perhaps a case of knowing the result they wanted to get-not an uncommon occurrence in science. The light deflection has, however, been accurately confirmed by a number of later observations. Another prediction of general relativity is that time should appear to run slower near a massive body such as the earth. Einstein first realized this in 1907, five years before he realized that gravity also altered the shape of space, and eight years before he completed his theory.
