To find giant black holes, start with our solar system’s center
A new study from researchers at Vanderbilt University suggests that to find the most massive black holes, measure the effects of their gravitational waves on the flashes of light coming from pulsars. The best location to do that is at the precise gravitational center of the solar system.
