A new crystal can bend light like a black hole would, causing the light to bow away from its usual straight path.
According to relativity, light and other electromagnetic waves can be influenced by gravitational forces. This is called gravitational lensing, and astronomers use it all the time to study massive space objects such as quasars. Recreating such an effect in a laboratory environment is difficult, given the need for a huge amount of mass, but scientists have long suspected they could mimic the phenomenon using crystalline materials.
"Much like gravity bends the trajectory of objects, we came up with a means to bend light within certain materials," Kitamura said in a statement.
