Physics Colloquium 20th November 2015 delivered by Professor Tom Ray This year marks the centenary of Einstein’s General Theory of Relativity. As is well known, physicists became convinced that Einstein was right after Eddington’s and Dyson’s famous expedition to measure the gravitational deflection of starlight. Recently the speaker has found the equipment that proved critical in testing Einstein’s theory after it being lost for almost 70 years. Remarkably its discovery has led to the finding that earlier eclipse data may have been conveniently ignored. The finger of suspicion points at Sir Frank Dyson, the Astronomer Royal, who was trying to protect Eddington from being conscripted into the British Army during World War I.
