Dark is the Moon [SEP] series
Dark is the Moon
Dark is the Moon is the third novel in "The View from the Mirror" quartet, by Ian Irvine.
experimental results, such as Galaxy rotation curves that imply dark matter or supernova observations that imply dark energy, could also potentially be explained by alternative theories of gravity (see, for example, MOND). Therefore, experimentalists believe it is important to make the most precise measurements of gravity possible, looking for any possible anomalies or confirming Einstein's predictions.
Precise ranging to the Moon can test the SEP since the Earth and the Moon have a different fraction of their mass in the energy component. Precision measurements are needed since
