可以让电磁波在超空间的第四维度深处传播，从而节省实际上走过的路程，实现超光速通讯。
It can allow electromagnetic waves to propagate deep in the fourth dimension of hyperspace, thereby saving the distance actually traveled and achieving faster-than-light communication.
电磁波相对于局域时空仍然是普通的光速，只是在常规三维宇宙看来”抄了近路“。
Electromagnetic waves still travel at the ordinary speed of light relative to local spacetime; it is only from the perspective of the conventional three-dimensional universe that they "took a shortcut."
虽然从压缩空间走了近路，但仍然不是瞬时的。跨恒星系通讯大约有几十分钟到十几个小时的延迟。
Although it took a shortcut through compressed space, it still is not instantaneous. Communication across Stellar systems has a delay of about several tens of minutes to over ten hours.
由于时空度规的影响，电磁波会自发地落回常规三维宇宙，因此需要每隔一段距离设置超空间通讯基站来进行信号转发。
Due to the influence of the spacetime metric, electromagnetic waves will spontaneously fall back into the conventional three-dimensional universe, so hyperspace communication base stations must be set up at intervals to relay signals.
超空间通讯时，需要精确知道接收方的坐标，才能把电磁波精准”投送“到对方所在的地点。
During hyperspace communication, the receiver's coordinates must be known precisely in order to accurately "deliver" electromagnetic waves to the other party's location.
超空间通讯带宽极小，通常只能传递文字数据。
Hyperspace communication bandwidth is extremely small, and usually only text data can be transmitted.
