This goo is rising and falling beneath the lunar surface — not unlike, say, ocean tides — which they concluded is likely caused by the gravitational push and pull of the Sun and Earth.
I wonder if it has to be a partial melt. We are finding that many asteroids are loosely bundled rocks. I wonder if maybe the moon has a similar structure. I have no clue how much pressure is under the surface and off it’s enough to fuse everything together.
Is the statement that it is a semi-liquid more or less confirmed? That is what I’m saying.
Is the moon’s diameter and composition enough to create a semi-molten rock? Or could this phenomenon be better explained by a loose set of rocks, which also displays characteristics of a liquid when in movement.
