The Clockwork Rocket: Orthogonal Book One 小说

The Clockwork Rocket is a hard science-fiction novel by Australian author Greg Egan and the first part of the Orthogonal trilogy. The novel was published by Night Shade Books on 1 July 2011 with a cover art by Cody Tilson and by Gollancz on 15 September 2011 with a cover art by Greg Egan. The novel describes an alien civilization being threatened by the appearance of hurtling meteors (which experience a totally different direction as time) entering their planetary system with an unprecedented speed and the implementation of an unusual plan: All the technology needed for an effective defense shall be developed on board of a generation ship launched into the void while only a few years pass back on the home world in the meantime due to time dilation. This is possible due to different laws for space and time in this universe, in which they have the same signature instead of different ones (meaning the sign of the signature for time is inverted), or which is alternatively described by a Riemannian instead of a Lorentzian manifold. The consequences on some of the physical concepts needed in the novel including time dilation and radiation, are described by Greg Egan with diagrams in the novel and also his website. The story is continued in The Eternal Flame and The Arrows of Time.
