Alexandru Lupsasca and Michael Johnson won the physics prize for their work on photon spheres — weird rings of light around black holes that may reveal a theory of quantum gravity.

In classical general relativity, that photon sphere is so thin that it barely even exists and is far too faint to be seen in the image of M87* taken with the Event Horizon Telescope.
