A promising alternative, proposed by Refsdal in 1964, relies on the inverse scaling of ${\\rm H}_{\\rm 0}$ with the delay between the arrival times of at least two images of a strongly-lensed variable source such as a quasar. To date, Refsdal's method has mostly been applied to quasars lensed by individual galaxies rather than by galaxy clusters.
