George Darwin. Portrait of Sir George Howard Darwin (1845-1912),British astronomer & geophysicist. Son of botanist Charles Darwin,George's most important work regarded the Moon's origin. He used a theory that stated that tides had slowed the Earth's rotation & caused the Moon to recede from the Earth. By extrapolating this into the past,he & Osmond Fisher proposed in 1879 that the Moon had been ripped from the rapidly- spinning Earth 4.5 billion years ago,leaving behind a basin that became the Pacific Ocean. Although the idea is now generally discredited,it was the first cosmological theory to be based on the principles of mathematical physics | |
