Guys, as I've just shown in my previous post, this picture (in Ski's post) is easily explainable in the RE model.
First of all, notice something: the darker portion of the Moon is not completely black, but obviously dimmer.
Now look at this picture regarding the RE model again:

Note that there is a shadow cast on the Moon (in the leftmost and rightmost positions) which covers only a portion of it. Notice also that the Moon is being shadowed by the Earth and is in the
penumbra, not the umbra. The difference is that the umbra is completely dark (a total Lunar eclipse) and the penumbra is only slightly - but noticeably - darkened. Finally, note that in Ski's nice picture (and the article), both the Moon and the Sun are visible. Observe (from the above diagram of the RE model) that this is exactly what is predicted.
Both the Sun and the partially-obscured Moon should be (and are) visible in the RE model.
I'll take a moment on this comment now:
If that's the shadow of the earth on the moon, then the sun must be an equal distance below the horizon as the moon is above the horizon. Hence, since it is not pitch dark, this clearly cannot be true. A stunning disproof of RET.
This is what I wanted to dispel at the top of my post.
In order for the Earth to cast a shadow on the Moon, it is not necessary that the Sun be directly opposite the Moon, as you say.
However, I think what you meant to say is that the Sun must be directly opposite the Moon (with the Earth in between) if the Moon is to be
completely dark, which is what we know as a Lunar eclipse. That is, of course, very true - and you can even see it in the picture I included above.
However, one can plainly see that a
partial shadow in the
penumbra is possible in the RE model with the Sun
not directly opposite the Moon - which is what is called selenelion and is observed in Ski's picture.
Thanks, I hope that helped.
be cool
