There is a difference between "intercept" and "absorb." A small part of the solar radiation incident on the Earth is intercepted by the atmosphere and refracted by it but not absorbed. That is why some sun light falls on the moon during a total eclipse. I hope you will not try to say that light passing thru a prism was not intercepted by the prism. Perhaps you also tell me that the Brits did not intercept German messages in WWII after they had a working Enigma code device as they did not block it, but let it reach the Germans? Not that it matters, but I will note that relatively little of the blue light passing thru the Earth's atmosphere falls on the moon during a total eclipse of the moon as it is much more strongly scattered (inverse fourth power of the wave length). That is why a time exposure for the moon with color film, shows it quite reddish moon, not a white like the full moon. Some, especially the Vikings, who don't understand this, think the reddish color is due to the lower reflection by the moon's surface for shorter wave lengths* but then are nearly** at a loss to explain why the full moon is not reddish too after the eclipse is over. That reddish color gave support to the old Viking explanation for the lunar eclipse. I.e. the moon was being eaten by a great wolf. They would beat their swords against their shields to scare the wolf away and that always worked. The red color was due to a little blood. If the wolf ate the moon, then night time raids to pillage England would be much more difficult. So it was every Viking's duty to make a much noise as he could. Thor might even electrocute those who did not do their duty. * Admittedly they did not put it in these modern terms, but idea was the same. ** Their myths don't go into this. Perhaps the hungry wolf quickly lapped up the blood before leaving. Some the wolfs did get a good meal as all the Vikings were sleeping - You can see the missing pieces we moderns call "craters." It all makes sense, even predictions and was confirmed in many "noise to save the moon" experiments. I don't know if any wise Vikings concluded the wolf had a quite circular mouth or not from the crescent shape of the partial eclipse and the generally round shape of the craters. They did not publish many scientific observations. Another they could have made was the wolf was so frighten by their noise that it was almost immediately sick and vomited back the bite it had taken during the partial eclipse. Sing with me: Give me that old time religion, "gibe me" that old time religion! It was good enough for Lars and Olsen so it good enough for me.
