Technicly though a sphere cant be lite from all sides at once by one sun so it does really.
Try shining a torch at a snocker ball, it will have a dark side just like any other planet or ball.
:grin: | What do you think that proves? Presumably you know about the orbits of the Moon and the Earth. No part of the Moon's surface is permanently hidden from the Sun. |

Please don't refer to it as the "dark" side; the two terms refer to two different things, and the far side receives as much sunlight as the near side. Because the moon's rotational period equals its revolutionary period, the same side faces the Earth and thus we can't see what's on the far side. Over a period of time, we actually can see more than 50% of the moon's surface because its elliptical and inclined orbit create an apparent wobble its position. It wasn't until spacecraft went behind the moon (beginning with the Luna 3 craft in 1959) that we got our first ever looks at the far side.

yes i read and replied to this a bit too quickly - i was talking about the far side, but didnt expect to get insulted about being irish because of it - inn must have just forgot his medication
basically it IS possible there are any number of things on the far side of the moon even alien bases, just as it is possible there is nothing but craters |

The Irish insults are way past their sell by date. They belong in the 70's and should be buried along with flares and racism.

true - although people like my grandfather are still bitter towards the english (actually hatred would be more accurate) - although he has his reasons - eg: when he was 16 and went to england to work the pubs had signs 'no dogs, no irish' - when he came home catholics in northern ireland were endlessly harrassed during the troubles by the UDR and RUC not to mention the loyalists - when he was a young man it wasnt 'one man one vote' etc etc etc... but its all history now |
