The glow on the opposite side of the GUFO is something that really needs explaining though.
I'm not sure if you where directing that at me, or if you meant in general. But I wasn't sure if the image explained it right so I'll recap, The light behind the "Moon" it is a hole, the hole is the other open point into guff, which is open and has always been ever since second impact. To me, second impact isn't 'finished' nor was it 'stopped' like the others that came after it. It's merely paused. (again, just a theory)
Also, this theory doesn't involve time travel at all. (though I did throw a loose theory about gendo going into guff to avoid the time loop that IS instramentality in order to see yui, but is a different theory all together)
Since the door of Guff FIRST opened at the south pole during 2I, guff and everything inside it, have been part of our time continuem. Only when both doors are closed does it exist in it's own realm (or something....lol) My point I'm trying to make is that the white moon sucked up into guff during 2I doesn't have anything to do with time travel etc.
