Tidal locking means that the denser side of the lighter body always faces the heavier body, and the less-dense side of the lighter body already faces away from the heavier one.

The moon is tidally locked to the Earth, which is why it has a dark side.

There is no dark side in the moon.

There is a far side.

You're right, but I'm pretty sure that "The dark side of the Moon" is a proper name at this point.

It's dark like the darknet is dark... Occluded.

So the Apollo "earthrise" photos are just "earth"?

[archgoon]

No; they weren't taken from the moon; they were taken from the Apollo 8 spacecraft, which was orbiting, so the Earth did in fact 'rise'.

[quakeguy]

Yes, Earth does not move significantly on the moon sky, if i remember right. It does rotate though.

Edit: Archgoon is right, the photos were taken from the orbiting module, so a rise happened.
