Faxes from the far side of the moon
We tend to discuss (understandably) how we don't see the far side of the Moon, discuss the difficulty of the "radio shadow", and are delighted to occasionally see pictures thereof.<p>Consider the reverse: someone (yes, hypothetically) living their life on the far side of the Moon would be completely unaware their quiet home is just 1.3 light-seconds away from a brilliantly reflective orb teeming with life.
