Optical analogues of gravity let scientists interrogate astronomical phenomena that are otherwise difficult or impossible to study. Figure 1: Black holes, which affect light and matter in a profound ...

A longstanding goal in physics has been to link general relativity with quantum theory and so unify the forces of nature. Theories of quantum gravity, however, are plagued by the weak theoretical ...

Can one see through a scattering medium like ground glass? Conventionally, such a feat would be deemed impossible. As light travel through an opaque medium, the information contained in the light ...

Currently, the heritage of human civilization depends on the preservation of digitalized information, including character, image, audio and video, which spawn countless data. The resulting information ...
