NASA Lunar Scientists Develop New Theory On Earth And Moon Formation

NASA Lunar Scientists Develop New Theory On Earth And Moon Formation: Challenges Theory That Giant Collision Of Two Planets May Have Produced Both Bodies New research, funded by the NASA Lunar Science Institute (NLSI), theorizes that our early Earth and moon were both created together in a giant collision of two planetary bodies that were each five times the size of Mars. This new theory about how Earth’s moon formed is challenging the commonly believed “giant impact hypothesis.”
