As reported in a recent paper on the physics website arxiv.org, the scientists simulated the black hole by sending sonic waves through a form of matter called Bose-Einstein condensate (BEC). BEC is a gas the exists only at the freezing temperatures near absolute zero, and the same equations that explain how sound moves through the condensate also describe how gravity effects light.
Using specially selected sounds waves, the scientists created a region within the BEC from which light could not escape. This is the first time anyone has succeeded in creating a so-called "sonic black hole", although researchers have been trying for almost 30 years. Theoretically, the same phenomenon that causes real black holes to emit Hawking Radiation will also cause the artificial black hole to emit them, too.
And while researchers have yet to observe any Hawking Radiation, they are clearly well on their way. Using sound to create a black hole? Chris Cornell would be proud.
They created a black hole, and a very powerful artificial gravity, which also created an artificial Ergosphere, thus enabling FTL travel (pls see links below). They had to concoct a stuff made up of 'probabilistic particles' - the black stuff, which is the stuff of Quantum Mechanics, to manipulate the random fluctuations of space and generate gravitons - the hypothetical gravity particle. From the film, it might be some kind of Bose-Einstein Condensate, any superfluid, or something else.

So this could mean we are half way to time travel right?

Personally, I think the "analogue of a black hole" is a bit misleading considering black holes are supposedly a function of warped space caused by gravity, which this demonstration is clearly not.
