Of course, a Greek *calculated* the diameter of the earth over two thousand
years ago from the length of shadows at two cities. And every sailor knew
why ships dipped below the horizon, without falling off the edge :-).
However that didn't stop the Church still claiming the earth was flat, and
the centre of the solar system/universe up until a couple of hundred years
ago. So people weren't *allowed* to admit otherwise when the church
controlled the courts, no matter how many thought like Galileo.
