Predictive astrology


Predictive astronomy did not begin with Hipparchus, and of course his model of the universe was geocentric. Apparently Hipparchus tried to calculate a heliocentric system but gave it up when he found that orbits could not be circular as required by the current conception of the universe as taught by Plato and Aristotle.
