What is the significance of synchronous rotation of the moon in relation to its orbit around the Earth?

Well, darling, the significance of synchronous rotation of the moon is that it spins on its axis at the same rate it orbits around the Earth. This means we only see one side of the moon, which is pretty darn fabulous if you ask me. It's like having a one-sided relationship with that gorgeous hunk of rock up there in the sky.
