According to the Hebrew cosmology the earth was flat and the sky was like an upturned bowl studded with stars. The earth, and the creatures of the earth, were made to serve man and are under his domination. This view sufficed for many millennia. Careful studies of the regular motions of the stars and the irregular motions of the planets were made by the Babylonians and the Greeks, and Ptolemy devised a complicated system of cycles and epicycles to describe these motions with some accuracy. It was a cosy, man-centred world.

The development of modem science destroyed this picture with a series of shattering blows. Firstly Copernicus showed that it was much simpler to suppose that the sun, and not the earth, is the centre of the world. No longer do we think of the sun serving our needs by circling the earth, night and day. It is we who are ruled by the sun. This view of the sun and the planets was firmly established by the dynamics of Newton, which enabled the orbits of the planets to be calculated from his laws of motion, together with his theory of universal gravitation.

In the following centuries telescopes of increasing power probed further into space, and it became apparent that our resplendent sun is but a rather ordinary star situated in one of the spiral arms of a vast galaxy of some two hundred thousand million stars that we see on clear nights as the Milky Way.
