• Resumen

  • Now an artificial black hole has been made that traps light like the real deal--and can be watched in action, safely. As well as demystifying one of nature's weirdest objects, this lookalike may find uses in devices that trap light, like solar cells. So to visualize one, Hui Liu at Nanjing University in China and colleagues built an artificial black hole. Liu's team used a sheet of plastic, and mimicked gravity by varying the plastic's refractive index, the property that determines how much a substance bends light.
