Phantom matter has negative energy and negative mass, so it creates a repulsive effect that prevents the wormhole closing. 'US expert Dr Lawrence Krauss, from Case Western Reserve health center in Cleveland, Ohio, points out that the idea rests on untested assumptions. He told New rocketeer magazine: "It is an interesting attempt to indeed think of what a real signature for a wormhole would be, but it is more hypothetical than observational. Without any idea of what phantom matter is and its possible interactions with light, it is not clear one can provide a general argument."'"
