A team at China's Southeast University in Nanjing have beat the Large Hadron Collider to creating a black hole. While it won't destroy the world (we hope), it acts in a similar fashion to a black hole, trapping all the electromagnetic waves that approach it and spiraling them inward.
More accurately called a "omnidirectional electromagnetic absorber," the device converts the energy of the spiraling radiation it absorbs into heat. The device, which absorbs 99% of incoming electromagnetic waves, could find its way into heating and cooling systems, or even into cameras and other electronics.
That is, if something doesn't go wrong and the universe gets swallowed up instead.
