Concave mirrors are sort of like parabolic dishes, in that the parallel light rays bounce off the curved-in surface and bounce to the focal point, which you can picture as being where the center ...

Mirror matter arises as a way to keep symmetry in quantum mechanics. All modern physics recognizes (and incorporates) three basic symmetries: reflection, rotation, and translation.

Warping one surface of two parallel mirrors doesn’t just alter the result a bit, because the planes feed off each other’s view, the final product is an exponentially skewed show.
