WHAT is the difference between astronomy and astrology? That's easy: astronomy is the scientific study of celestial objects, while astrology is a load of hokum. Anyone with the most basic understanding of science knows why. Astronomy passes the acid test of real science: its claims are always capable of being debunked - in other words, they are falsifiable.
Identified as the defining characteristic of real science by the philosopher Karl Popper more than 70 years ago, falsifiability has long been regarded by many scientists as a trusty weapon for seeing off the menace of pseudoscience.
The late Viennese thinker has been lauded as the greatest philosopher of science by the likes of Nobel prizewinning physicist Steven Weinberg, while Popper's celebrated book The Logic of Scientific Discovery was described by cosmologist Frank Tipler as "the most important book of its century".
