It’s not like we’re grasping at straws due to the recent end of the Harry Potter film series or anything, but we’re pretty sure that Harry and his magical universe exist. Xiang Zhang of UC Berkeley and his colleagues have, over years of research, developed an “invisibility cloak,” which is a material that changes the path of electromagnetic objects around a wave so as to render it imperceptible.
Granted, the cloak only hid an object around the diameter of a red blood cell, but it is still a significant development in this type of material. Most cloaking materials (kind of like the inferior invisibility cloaks that were not as exceptional as Harry’s) hide objects from vision by using infrared waves or microwaves, which are just out human sight range.
This material hides objects under layers of silicon nitride and silicon oxide and then refracts light away from the lump that the object makes, so that the cloak ends up looking smooth. We don’t care what you say, Muggle — magic is totally real.
