2022 $5 Wallal Centenary – Australia Tests Einstein’s Theory 1oz .999 Silver Proof Domed Coin
In 1922, the eyes of the international scientific community were focused on an expedition of scientists to Wallal, Western Australia to photograph a total eclipse due on 21 September.
Precise measurements of the apparent position of the stars near the eclipsed Sun were photographed and provided the evidence supporting Einstein’s revolutionary Theory of General Relativity!
The expedition was organised to conclusively prove Einstein’s theory following the first photographic evidence captured during the 29 May 1919 eclipse expedition led by Sir Arthur Eddington.
Teams from multiple countries as well as local astronomers from the Perth Observatory formed the 1922 expedition led by William Campbell from the Lick Observatory (USA), who were successful in taking the images of the eclipse that provided the evidence to support Einstein’s theory.
