not nonsense, just open mindedness. a galaxy has a certain gravity field to it, which could effect the curvature of space in its vicinity. since to my knowledge no one else has suggested this theory, there is no name for the situation IF it exist. All the photos I've seen before were taken off galaxies on the far side of other galaxies. Could the mass of the galaxies in between have some effect on the timing of the light getting to earth? Personally, i don't see why it cant. I certainly will not say it cant happen. you would have to ask someone who had a lot more knowledge in the subject than me. If you have some way of asking this question to one of them, id love to hear the answer.

the more man learns, the more he realises, he really does not know anything.
