The shadow of a Black Hole (2019) and the problematc measurement of light defecton by the sun in 1919
Por Rui Agostinho (FCUL).
The Event Horizon Telescope (EHT) has published in 2019 the first ever image of an Event Horizon, from the very massive central black hole in the M87 galaxy. The team has chosen to publicize it 100 years after the first measurement of light deflection by a strong gravitacional field, which was a landmark for the Theory of Relativity in 1919. This new image did not require a technological revolution and neither did the images taken in 1919, however they all imprint the History of Physics.
