Updated Theory: A Huge Chunk Of Earth, Blasted Away In A Collision, Is Now The Moon
Moon Formation In The Late Hadean Period courtesy of the Smithsonian Air and Space Museum New findings demonstrate how the moon could have been made from Earth parts, not kamikaze-planet pieces. New simulations of a crash between Earth and a protoplanetary sister long ago could have produced a moon that's chemically similar to our planet, according to a new analysis. It bolsters a theory that the moon is part of Earth, and it helps settle a question about how this could be physically possible. Since around the time of the Apollo missions, lunar scientists have theorized that our moon formed after a horrendous collision between Earth and another world, which sheared off part of this planet. But all the while, there's been a major disconnect with reality and the satisfying theoretical explanation of this concept. If that's what happened, then the moon should be primarily composed of material from the collider,...
