The Big Picture: Photographing the Black Hole
at the Center of the Galaxy
Dr. Larry Price
     Starting in April 2017, international researchers linked radio telescopes around the world, aiming them simultaneously at Sagittarius A* (pronounced A-star), the enormous black hole at the center of our galaxy. The goal? To take a picture of a supposedly invisible object in space, the black hole itself. Data from the combined telescopes are currently being analyzed. What will we learn? What will it all mean? Success will provide the first opportunity to measure directly the properties of black holes, still-mysterious objects which have only been observed indirectly until now. It will provide an incomparable test of Einstein’s General Theory of Relativity at extreme values of the gravitational field. And, perhaps most importantly, it should give us important clues with which to construct the still-elusive quantum theory of gravity. Dr. Price will explain all of this, without assuming technical knowledge, and provide us all with a good framework for following what should be one of the hot scientific stories of 2019 and beyond.
