Australian scientists used an advanced 3D printing technique to create a super strong, super lightweight new "metamaterial".
In the future, these structures may be used to develop compact optical devices, as well as to create an 'invisibility cloak.'
Engineers believe that continued advances in creating ever-more exotic and sophisticated human-made materials will greatly improve their ability to control light at will.
(PhysOrg.com) -- Metamaterials researchers Yaroslav Urzhumov and David Smith, working at Duke University have built a simulation of an object that can move through water without leaving a trace and claim it
(PhysOrg.com) -- By observing the way that light moves inside a metamaterial, researchers have reconstructed how spacetime has expanded since the Big Bang. The results provide a better understanding of why time moves in only one direction, and also suggest that time travel is impossible.
