Ok, so what % of this "ground hog day" universe is merely a reflection/refraction of some other portion? What if our telescopes are essentially kaleidoscopes? We recently learned from "Interstellar" that rotating black holes map their backgrounds into fractal patterns reminiscent of Newton iterations. What if a significant fraction of the light that we see in the sky is coming from the same places, but at different times? After all, if there is so much dark matter, it should be capable of quite a bit of lensing. At 02:21 PM 3/5/2015, Warren D Smith wrote:

A supernova exploded. It then appeared 4 times in 4 places in the sky. This seems to prove gravitational lensing happens... in case anybody doubted it, it now seems a lot more proven. The relative time delays are of order 10-100 years and more images of it will probably come to those who wait another 10-100 years.
