Claudius Ptolemy, an astronomer who lived in Rome about 100 AD asserted that the sun orbited the earth. It was logical to presume the sun was orbiting the earth, since the sun seemed to arrive in the morning and leave at night, return the next day and leave that night.
Many centuries after Ptolemy’s model was formulated, Polish mathematician and astronomer, Nicolaus Copernicus revealed a different way of seeing things, a different way of perceiving consciousness.
In 1543 he introduced the idea that the sun was the centre of the solar system. At the time Copernicus’ sun-centred theory was considered radical thought that went unproven until science eventually had the tools to confirm his reality.
Although centuries ago it was commonplace to hold the belief that the sun orbited the earth, no one asserts that old reality now.
The story of the shift from the belief of an earth-centred to sun-centred universe is an example of the summation over time of our experiences. Even culturally, when we accept new and contradictory information, the old reality or program of thought is pruned away.
