Royal Australian Mint RA Mint – Wallal Centenary Aus. Tests Einsteins Theory $1 Unc. Coin

The Royal Australian Mint commemorates 100 years since Einstein’s Theory was confirmed at Wallal, Australia.

100 years ago, the eyes of the world were focused on an expedition of international and Australian scientists to Wallal, Australia where conditions would be ideal for photographing a total eclipse due on 21 September 1922. The photographic images taken during this ground-breaking expedition allowed for the precise measurements of the apparent position of the stars near the eclipsed Sun giving scientists the evidence proving Albert Einstein’s revolutionary Theory of General Relativity as correct.
