I'm glad they settled this one; however, to my knowledge nobody thought Anti-Matter meant "Anti-gravity" w/rt Alcubierre warp drive. That's not what they meant by 'exotic matter.' But ok. sure. There was doubt that exotic matter could exist at all, and nobody had doubts that anti-matter could exist. I think there is something lost in the translation here. (No I'm not saying that warp drive still must be possible, I just think people, including the article writers, are conflating things.)
