I read that a long time ago (tens of millions of years) the moon was further away and rotated as it went around the Earth. As the moon is falling in to the earth (tens of bilions of years to impact) the moon became tidal lcked to the earth.
>>Far side of the moon ‘could have been visible from earth’<<
I’m pretty sure there was nobody here to see it 3.9 billion years ago.

And non muslim.
This ranks right up there with the most useless semi-facts of all times, not to mention the most egregious waste of time and money list...
This is a picture taken by Voyager 1 in 1990 as it sailed away from Earth, more than 4 billion miles in the distance

Not "about" 4 billion?

[snip] According to earlier computer simulations, the moon’s western hemisphere as viewed from Earth should have about 30 per cent more craters than the eastern hemisphere. That’s because the west always faces in the direction in which the moon orbits, which makes it more likely to be hit by debris, for the same reason that more raindrops strike a moving car’s front windshield than its rear. [end]
BTW, that explanation doesn’t make any sense. The moon’s faces are approximately equally likely to receive an impact — when the Moon gets one from behind (so to speak) the crater would just be a bit smaller (all other things being equal, and they probably never are).
Physics News Update Number 16 (Story #2)The far side of the Moon, impossible to see from the Earth, was recently photographed by the Galileo spacecraft on its way toward Jupiter. New information about the mineralogical composition of the far side's crust was recorded and pictures revealed the largest impact basin yet seen on the moon, more than 2000 km in diameter and so deep that is may have penetrated through the crust to the moon's mantle.

By some theories, at one time the far side of the moon was ON the earth.
