This article on Slate claims the invention of an artificial black hole. Too bad that the device described is really a "black body" rather than a "black hole". A black body is a device that is a perfect absorber of radiation, no radiation is reflected, it is all absorbed. In principle an ideal flat black paint would form a black body. In practice an opening into a box, whose interior is painted black will be even blacker than the paint alone.
A black hole is a gravity field so strong that the escape velocity exceeds the speed of light.
And Slate doesn't know the difference. Typical poorly educated newsies.
