„The earth,” read out my friend, hesitating a bit as the translated the Latin, „the earth, in relation to the distance of the fixed stars, has not appreciable size and must be treated as a mathematical point!” [from Ptolemy’s Almagest]

There was a moment’s silence.

“Did they really know that then?” said my friend. “But – but none of the histories of science – none of the modern encyclopedias – ever mention the fact.

The enormous size of the universe and the insignificance of the earth were known for centuries, and no one ever dreamed that they had any bearing on the religious question. Then, less than a hundred years ago, they are suddenly trotted out as an argument against Christianity. And the people who trot them out carefully hush up the fact that they were known long ago.
