 Present: The Einstein Lens and

 a Tale of Two Eclipses

Join Dr. Tom Ray for a discussion on the discovery of equipment that was critical to the Eddington/Dyson solar eclipse expedition in 1919 - an expedition which provided one of the earliest confirmation of Einstein's theory of general relativity.

This year marks the centenary of Einstein’s General Theory of Relativity. As is well known, astronomers became convinced that Einstein was right after Eddington’s famous expedition to measure the gravitational deflection of starlight in 1919. Recently the equipment that proved critical in testing Einstein's theory has been found after being lost for almost 70 years. Remarkably its discovery has led to the amazing finding that Eddington's expedition may not have been necessary. The finger of suspicion points at Sir Frank Dyson, the Astronomer Royal, who could have been trying to protect Eddington from being conscripted into the British Army during World War I.
