Furthermore, the findings bolster the theory that the moon formed when a giant, Mars -size protoplanet slammed into the young ...

Also, the moon does have some volatile elements, like water, trapped in rock — but a giant-impact, giant-energy event should have gotten rid of those. Despite those caveats, the giant impact ...

The Moon seems to be keeping things uneven when it comes to water. A recent study of samples scooped up from the far side and ...

The idea of more than one moon is the latest in a series of tweaks and challenges to the giant impact theory. “I think that some version of the giant impact theory will survive, but I don’t ...

The accretion hypothesis proposes that the Moon was created along with Earth at its formation. The fission theory suggests Earth had been spinning so fast that some material broke away and began to ...

The moon’s birth still sparks debate among scientists. Most support the “giant impact” theory involving a body named Theia. Competing ideas—like the moon splitting from Earth or forming ...

As such, it has some questions to answer. Among them is whether its water content is compatible with the giant impact theory of the moon's formation. Modeling of the giant impact scenario suggests ...
