I suppose it would be possible for there to be street lamps on the moon, thus casting shadows.
But if you look at the shadows they all point to a single light, a great distance from the moon.
That light can either be hitting from the side, or straight above, or hitting from the other side, but the shadows always go the same way on any given day so it's not like local light.
I think this is why Mark Sargent has taken the stance that the sun, moon, and stars are projected upon [the dome], by an ultra high definition system, using super LED technology, and a combination of 2D and 3D imaging..
But I'm even having doubts about that being a workable model.
Even if the sun was a projection on the dome, and it was projected to be over behind Alaska for the correct position in the sky to be seen from Australia, it would still be projected onto the dome at a point that was closer to Alaska during the Australian Equinox Sunset.
So we'd have to basically say that it was being holographically projected at a much much lower level.
