First, if you were to play a tape of light\u2019s behavior forward and then backward, you would see it behave in the same way moving in both directions in time. This is called time-reversal symmetry. And second, light, which can move through the world <a href=\"https:\/\/www.livescience.com\/50326-what-is-ultraviolet-light.html\">as a wave<\/a>, has what is called polarization: how it oscillates relative to the motion of the wave. That polarization usually stays the same, providing another type of symmetry.<\/p>\n<p>But inside this ring-shaped device, light both loses its time-reversal symmetry and changes its polarization. Inside the ring, light waves turn circles and resonate with one another, producing effects that don\u2019t normally exist in the outside world.
