Colliding black holes could clock the universe’s expansion rate

Scientists may have found a way of using the collisions of black holes to measure the rate at which the universe is expanding. The violent mergers of black holes launch ripples in space-time called gravitational waves, and a new technique measures changes in these signals that occur as they experience the universe’s expansion.
