Although faster-than-light travel is commonplace in science fiction, ordinary matter in the ordinary world must obey the laws of physics. The speed of light is the speed limit in the Universe. Only massless particles such as photons can travel at the speed of light. This makes any observation of something appearing to travel faster than the speed of light rather astonishing. Such observations have been made in astronomy and is the focus of this chapter.
