Does anyone know or have heard of any object that will react or change physically to light (and not necessarily because of temperature)?
I know materials expand and contract with temperature, but do any materials or objects change their physical form by light or radiation alone? I thought photovoltaic cells, or even pigment in ones skin, but that seems more of a chemical reaction than a physical one.
Sunflowers?? Haha just kidding, but for real. Anything out there today of this nature.
