When knowledge is imperfect, vision funnelled through a tunnel, and grander possibilities exist only in the realm of philosophy or religion, any scientific change can come as a deluge drowning out the belief systems of an already abiding humanity.That’s exactly what happened in the western world when Copernicus whisked away a notional rug from under our feet that had long meant we — meaning our world in all its astronomical definitions and other senses — were the centre of the universe, read, creation. Suddenly all the observable heavenly bodies in the firmament were no longer seen to be orbiting the Earth as their magisterial focus; rather a heliocentric alternative was offered with empirical evidence which proclaimed that the Sun instead held the planets in its gravitational thrall. Geocentrism was dead forever. Soon tiny Earth would also be dwarfed by other gassy giant planets in its own backyard.
