Butterflies, Rorschach tests, and classically attractive faces all look the same when flipped left-to-right. In physics, a symmetry is when the laws of physics are unchanged due to some transformation of coordinates. We’ve seen examples where it is - the universe is symmetric to coordinate shifts in space, time, and even the rather abstract phase of the wave function. So it might be surprising to learn that with all the weird ways in which the universe IS symmetric, it’s NOT entirely symmetric under this most intuitive one. The laws of physics work differently in the universe of the mirror.
