To measure the masses and spins of black holes, scientists want to follow clues left behind by light that takes a round-a-bout journey, bends around these voids, and ultimately shines toward us.
The crew, from Princeton University and Los Alamos National Laboratory, has performed complex computer simulations to show how two telescopes — one on Earth, the other in space — can work together to make the idea a reality. In other words, these devices could help us detect light that has basically been on a trip around a black hole.
