A "Hot Young Solution to Faint Sun Paradox" earlier offered hints that the speed of light may be slowing. Human exploration of the Moon has provided a further test. The Lunar Laser Ranging Experiment from 1969 measures the Moon's recession at 3.84 cm/yr, anomalously high. Geology and paleontology indicate that lunar recession has been just 2.9 cm/yr (Bills and Ray, 1999). A Theory of Space/Time proposes that speed of light c is related to age t of the Universe by GM=tc3. For a Universe of 13.7 Ga, predicted c change is 1 in 41.1 Ga. Multiplied by the Moon's distance of 384,402 km, the Moon will appear to recede an additional 0.935 cm/yr. The anomaly in lunar recession is precisely accounted for, indicating that c changes to this day. Change in c is precisely corroborated by Type Ia supernova redshifts. Earth's climate record, when compared to solar models, has provided further corroboration. In summary, data from three truly independent sources indicates that c has changed as predicted. Future lunar exploration with more advanced equipment will doubtless lead to more surprises.
