Heino Falcke is professor of Astroparticle Physics and Radio Astronomy at the Radboud University in Nijmegen. Heino has built a radio antenna that will fly onboard a Chinese satellite behind the moon to measure faint signals from the early cosmos and he found a way to image black holes with radio dishes from the ground. In his talk, he’ll explain how it is possible to make the invisible visible and the role the Event Horizon Telescope plays in that process. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at www.ted.com/tedx
