You know, when you grope for luna. (The moon as chimera.)

Two moons above Earth may have collided to create one, study says - latimes.com

Once upon a time, the sky above Earth may have held two moons — until they smashed into each other to create the lunar body we know today. Such a collision early in the solar system's history could explain why the moon is lopsided, and why its far side looks so different from the face we can see, according to a report in Thursday's edition of the journal Nature.
Heard this on NPR this morning on the way to work as well, but didn't think it was a new idea? Hasn't this been, if not generally accepted as likely, widely discussed before?

+5 cdog points* if you get the "grope for luna" reference in the post title without using search.

* cdog points have no monetary or measurable value. May not be exchanged for ... anything.
