2022 $1 Wallal Centenary - Australia Tests Einstein's Theory Al/Br Uncirculated Coin in CardIn 1922, the eyes of the international scientific community were focused on an expedition of scientists to Walla, 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.Einstein's theory states that massive objects, such as planets and stars, curve the fabric of space and time around them. The theory predicts that light from a distant star passing near the Sun will follow the curve as it travels to the Earth, making the star appear to be displaced in the sky; it even predicts by how much the stars will appear to be out of place@Normally stars near the Sun are overwhelmed by the bright sky but during a solar eclipse, the Moon obscures the Sun, creating a sky dark enough that stars can be photographed. Einstein's 107-year -old Theory of General Relativity predicated the existence of black holes and gravitational waves.The coin's reverse design illustrates the location of Wallal, Australia, the narrow band from which the eclipse could be seem and the Earth sitting within a funnel depicting Einstein's Theory of General Relativity.Each coin is encapsulated and housed in a presentation card.Each coin's obverse features the effigy of Her Majesty Queen Elizabeth II designed by Jody Clark.Issued as Australian Legal Tender.ALBERT EINSTEIN and/or EINSTEIN are trademarks or registered trademarks of The Hebrew University of Jerusalem, represented exclusively by BEN Group, Inc, and are used with permission.
