Using supermassive black holes to measure cosmic distances

Copenhagen, Denmark (SPX) Nov 28, 2014
One of the major problems in astronomy is measuring very large distances in the universe. The current most common methods measure relative distances, but now research from the Niels Bohr Institute demonstrates that precise distances can be measured using supermassive black holes.
