论文摘要
Braneworlds绕着绕过一个额外的紧凑尺寸旋转并旋转，以表现出穿透散装的田间的静光传播。这种繁殖要么是不可否认的各向异性，要么是在特殊框架中变成各向同性的，具体取决于brane的运动和散装中的方向。对于一类增强的观察者，此类磁场的波前将分成两个双曲体组件，一个将向前传播，另一个以超光速度向后传播。尽管有这些影响，但没有因果关系，也没有tachyon。检测天体物理各向异性静脉静脉传播速度将为存在额外压实的维度和信息的信息提供标志。
Braneworlds winding and spinning around an extra compact dimension manifest superluminal propagation for fields penetrating the bulk. This propagation is either irreducibly anisotropic or one that becomes isotropic in a special frame, depending on the brane's motion and orientation in the bulk. For a class of boosted observers on the brane the wavefront of such fields will split into two hyperboloid components, one propagating forward and the other backward in time at superluminal speeds. In spite of these effects, there is no violation of causality and no tachyons. Detection of astrophysical anisotropic superluminal propagation velocities would offer a sign for the existence of extra compactified dimensions and information on the state of our braneworld in the bulk.
