Abstract (provisional)

Background

Studies of the Moon, with thanks to NASA and Johnson Space Center, have quantified an anomaly in measurements of lunar orbital evolution. This finding may have significance for cosmology and the speed of light. The Lunar Laser Ranging Experiment from Apollo reports the Moon's semimajor axis increasing at a rate of 3.82 +/- .07 cm/yr, anomalously high. Findings Sedimentary data indicates a rate of only 2.9 +/- 0.6 cm/yr. From historical eclipse records we can accurately calculate a rate of 2.82 +/- .08 cm/yr. A detailed numerical simulation of lunar orbital evolution predicts 2.91 cm/yr. LLRE's laser light differs from independent experiments by up to 12sigma.

Conclusions

Several possible explanations are considered. The author's hypothesis proposes that the speed of light decreases at rate . This predicts that LLRE will differ by , precisely accounting for the lunar anomaly.
