Two Chinese scientists have successfully made an artificial black hole. Since you’re still reading this, it’s safe to say that Earth hasn’t been sucked into its vortex.
That’s because a black hole doesn’t technically require a massive, highly concentrated gravitational field that prevents light from escaping, as postulated by Albert Einstein. It just needs to capture light — or, to be more precise, electromagnetic radiation, of which visually perceived light is one form.

this isn't a black hole but an effect that absorbs e.m. radiation.

According to newscientist.com. it's 'made of 60 annular strips of so-called "meta-materials", which have previously been used to make invisibility cloaks.'
I want some of that material...

tallmansam:
it's "60 concentrically arranged layers of circuit board. Each layer is coated in copper and printed with patterns that alternately vibrate or don’t vibrate in response to electromagnetic waves."
interesting stuff!
