Janus Posted June 11, 2019 Share Posted June 11, 2019 Apparently, scientists are guessing this shrapnel is the result of a massive impact with an asteroid a few billion years ago.They say it covers roughly 20,000 square miles, making it larger than Denmark (17,000 square miles). How large an impact would be required to knock the moon off it's axis? https://www.thesun.co.uk/tech/9267203/moon-metal-structure-underground-aliens/ Link to comment Share on other sites More sharing options...

In fact even if the largest object in the asteroid belt — the dwarf planet Ceres — were to for some reason whack into the Moon it wouldn’t be destroyed nor knocked out of orbit. Not only is Ceres considerably less dense than the Moon but at 587 miles across it’s three and a half times smaller. Even a direct hit would be “the equivalent of a four-year-old trying to knock over an NFL lineman,” according to University of Hawaii astronomer Gareth Wynn-Williams in a 2013 Popular Science article." "According to the same article it’d take an object about the same size and density of the Moon itself impacting at a similar velocity — 0.635 miles per second — from the opposite direction to stop the Moon in its orbit, at which point it (or whatever was left of it) would begin to fall inwards."

petemcewan Posted June 12, 2019 Share Posted June 12, 2019 (edited) If it's on the backside of the Moon. It can be none other than the remains of "Morgan The Moon 's " spaceship. Edited June 12, 2019 by petemcewan Link to comment Share on other sites More sharing options...
