Yeah I saw that article too. The problem, which they mention in the article, is that it's only possible with negative energy and negative mass. In order to use this theoretical method to transport even a small spaceship, you would need an almost infinite amount of mass to generate the negative energy imbalance that it would require.
There was one compelling argument I recall from a few years ago that said it wasn't impossible that such a distortion could exist, it's just impossible to cause the conditions to bring one into being where it didn't previously exist.
Either way the burden of proof on whether it's possible is on the advocates.
