Third-party evidence for Apollo Moon landings minus 6 million years. The test was done by a group of researchers headed by Alexander Nemchin at Curtin University of Technology in Bentley, Australia. The detection on Earth of reflections from laser ranging retro-reflectors (LRRRs, or mirrors used as targets for Earth-based tracking lasers) on Lunar Laser Ranging experiments left on the Moon is evidence of landings. Quoting from James Hansen's biography of Neil Armstrong, "": For those few misguided souls who still cling to the belief that the Moon landings never happened, examination of the results of five decades of LRRR experiments should evidence how delusional their rejection
Lunar distance (astronomy) Earth and Moon become tidally locked. This would occur when the duration of the lunar orbital period equals the rotational period of Earth. The two bodies would then be at equilibrium, and no further rotational energy would be exchanged.However models predict that 50 billion years would be required to achieve this configuration, which is significantly longer than the expected lifetime of the solar system. The average lunar distance is increasing, which implies that the Moon was closer in the past. There is geological evidence that the average lunar distance was about (i.e. 52 x the radius of the Earth, or
