And, you know, one of the best ways to track dark energy, which is the force that's causing the expansion of the universe to accelerate, is to see how far spread apart things are in the distant universe, to see how fast the universe is pulling apart.
The frequency of gravitational lensing, which can be measured by counting the number of gravitationally lensed quasars within a given quasar catalog, allows one to infer the expansion speed of the universe, because the accelerated expansion increases the distance to each quasar and therefore enhances the chance of gravitational lensing (Figure 2).
