Moon question.

[JulianO]

We always see on side of the Moon because it is gravitationally locked, therefore the near side feels more gravity than the far side, resulting in a uneven crust thickness.

It's tidally locked, but that doesn't account for the thickness. It hasn't always been tidally locked, and the crust is set now.

[NLO]

I thought the moon was closer to us and spinning faster on formation, and as gravity (ours and its) acted on both bodies they moved apart and it became tidally locked.
