• Opening plenary talk in 2019 for the Centennial International Conference celebrating the 100th anniversary of the 1919 famous solar-eclipse expedition and experiment that confirmed the theory of General Relativity of Einstein. The conference took place in the town of Sobral in Brazil in May 2019 (exactly 100 years after the original expedition of 2019), where, at the time, the geographical location of the town allowed the best measurement of the deflection of light by the Sun during the eclipse. A key element is that Einstein’s theory of gravity predicts a deflection of light twice the size of that predicted by Newton’s gravity, and the Sobral’s measurement confirmed exactly that! The result in 1919 was a turning point in history confirming for good the theory of General Relativity of Einstein. The event in 2019 was sponsored by the International Union of Astronomy, involved many physics and astronomy societies, and was echoed all over the world, reaching the New York Times and the Washington Post. The event was a real journey thru space and time.
