Steve Desch says a group of scientists solved the problem of how the Moon formed in the 1980s .

Desch: A Mars -size object crashed into the early Earth , jettisoning molten material into space.

The early Moon would have raised gigantic tides on the Earth , which itself was mostly molten and spinning rapidly.

These tides took energy from the Earth 's spin and transferred some to the Moon ’s orbit, slowly pushing the Moon away from Earth .

This motion continues today the Moon still recedes from Earth about 2 inches per year.

Geochemists and geophysicists end up with different and contradictory hypotheses.

This happens partly because these fields use different kinds of measurements, but also because they speak very different scientific languages.

Overcoming this language barrier is hard, but sometimes bridging that divide can benefit researchers on both sides.
