Light kidnapped by black hole lookalike

摘要

How do you see an object when its gravity is so strong that not even light can escape it? Black holes are inherently mysterious for precisely this reason. 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.
