According to relativity, any wave that can travel through vacuum can do so only at c, because since vacuum looks the same for every observer, so should the mechanism allowing the waves to travel (since that takes place in the vacum) and therefore the speed at which the wave travels (I think), and since all other speeds will be different for observers in other frames. So how can matter waves travel faster than c? I konw wiki says it can because it doesn't carry information, but there has to be a mechanism allowing it to travel...er, right?
