Some stuff on the moon:
https://history.nasa.gov/SP-350/ch-12-3.html>They all worked well, with one exception, and were really producing useful data. One unexpected result came from the seismic experiment recording the impact of Intrepid on the surface after we had jettisoned it. The entire Moon rang like a gong, vibrating and resonating for almost on hour after the impact.i like to believe the moon is hollow. and while we are at oddities about the moon:

>“The best possible explanation for the Moon is observational error – the Moon doesn’t exist.’>"The Moon is bigger than it should be, apparently older than it should be and much lighter in mass than it should be. It occupies an unlikely orbit and is so extraordinary that all existing explanations for its presence are fraught with difficulties are none of them could be considered remotely watertight."Christopher Knight and Alan Bulter

>The Moon has astonishing synchronicity with the Sun. When the Sun is at its lowest and weakest in mid-winter, the Moon is at its highest and brightest, and the reverse occurs in mid-summer. Both set at the same point on the horizon at the equinoxes and at the opposite point at the solstices. What are the chances that the Moon would naturally find an orbit so perfect that it would cover the Sun at an eclipse and appear from Earth to be the same size? What are chances that the alignments would be so perfect at the equinoxes and solstices?
