Study claims Earth 's gravity caused tidal effects that melted the surface of the early Moon, effectively giving it a global facelift.

Understanding the nature of this lunar face-melting event could help pin down measurements of the Moon 's age, which vary depending on the sample and method.

Earth 's gravity gave the Moon an early facelift about 4.35 billion years ago , says Nimmo .

Earth 's oceans did not form until about 3.8billion years ago .

Nimmo notes that around this time period, Earth was still molten - not a smooth sphere, but lumpy.
