Smoke & Mirrors

[Whys]

Since we can establish the existence of an inter-galactic lensing effect, perhaps we should consider the possible existence of an inter-galactic reflection effect. I don't know by what process this might occur, but we should at least consider it. It could be that the universe is not as large as we think. Perhaps many of the much older galaxies we observe, are but the back side reflection of galaxies nearer to us. That view would also appear billions of years older, making it difficult to know when we are looking at two images of the same galaxy.

Any thoughts?

I also do not know what might cause an intergalactic reflection effect. If the mirrors were to form the boundary of the universe, they would have to be curved, resulting in the image becoming skewed, or straight, causing serious distortion at the corners. Also, there would still be symmetry remaining after billions of years which an advanced computer/determined human might be able to notice.

Any such intergalactic reflections needn't form the boundaries of the universe, but even if they did, distortion along the edges or corners is not a given. Consider the following diagram.
