In 1919, a solar eclipse led to the confirmation of Einstein’s theory of General Relativity that he had proposed three years earlier. If Einstein's theory was right, starlight should bend as it passes the sun. Researchers, one group led by Arthur Eddington and Edwin Cottingham on Principle Island off the West African coast and another group in Brazil led by Andrew Cromellin and Charles Davidson, set out to determine the changes in the position of stars in the sky near the sun relative to their position before and after the eclipse. Their data ultimately confirmed Einstein’s theory of general relativity. These results have been borne out by subsequent experiments conducted during solar eclipses.
Examining ancient records of solar eclipses at known places and times has also enabled scientists to elucidate the Earth’s past rotation rate. This has even allowed historians to translate ancient calendar systems into a modern calendar system.
It is clear, then, that solar eclipses have played an important part in the scientific endeavour. Is it merely an uncanny fortuitous state of affairs that the one planet in our solar system on which there are observers also happens to be the one planet with perfect solar eclipses that appear to provide optimal conditions for scientific discovery?
In their book The Privileged Planet, astronomer Guillermo Gonzalez and philosopher Jay W. Richards elaborate on this and many other uncanny coincidences that suggest that there is significant overlap between the conditions necessary for habitability and those that are conducive to measurability.
While this striking phenomenon does not by any means clinch the design hypothesis, it certainly adds to a growing cumulative body of data that suggests that our Universe was designed for intelligent life.
