Présentation de l'éditeur

In an alien universe where space and time play by different rules, interstellar voyages last longer for the travellers than for those they left behind. After six generations in flight, the inhabitants of the mountain-sized spacecraft the Peerless have used their borrowed time to develop advanced technology that could save their home world from annihilation.

But not every traveller feels allegiance to a world they have never seen, and as tensions mount over the risks of turning the ship around and starting the long voyage home, a new complication arises: the prospect of constructing a messaging system that will give the Peerless news of its own future.

While some of the crew welcome the opportunity to be warned of impending dangers - and perhaps even hear reports of the ship's triumphant return - others are convinced that knowing what lies ahead will be oppressive, and that the system will be abused. Agata longs for a chance to hear a message from the ancestors back on the home world, proving that the sacrifices of the travellers have not been in vain, but her most outspoken rival, Ramiro, fears that the system will undermine every decision the travellers make.

When a vote fails to settle the matter and dissent erupts into violence, Ramiro, Agata and their allies must seek a new way to bring peace to the Peerless - by traveling to a world where time runs in reverse.

THE ARROWS OF TIME is the final volume of the Orthogonal trilogy, bringing a powerful and surprising conclusion to the epic story of the Peerless that began with THE CLOCKWORK ROCKET and THE ETERNAL FLAME.

Egan almost always delivers grandiose books.
Having read them all, I feel this is probably the grandest achievement.
Maybe not the most breathtaking or the best story, though it's on par with other good ones, but definitely the most exhilarating theory and all-encompassing description.

Excellent (but very complex. So much so that there are diagrams and drawings about the rules of the universe all along the trilogy)

One thing though, Egan allowed a big inconsistency between the laws of his universe and the story, relating to what would happen for two particles (or even more, two bodies, one way bigger than the other) when their arrows in four-sphere are opposite one another.
No way they would interact "peacefully".
And the story could have avoided the problem (or at least minimized it).

Still, sheer genius.

3.0 étoiles sur 5 Very creative, a bit disappointing 12 janvier 2015
Par Amazon Customer - Publié sur
Format:Relié|Achat vérifié
I came across Clockwork Rocket some years ago, and it presented some fantastic (and oddly believable) concepts of an alternate universe operating with physics vastly different from our own. That book captured me with its detail on the shape-changing protaganists and how they functioned as a society. But it gradually drifted into Alternative Cosmology 101 and on up to post-grad level. Still, not so bad. The second book really layered it on as the Peerless traveled on its voyage. I'm not a physicist, so I had trouble grasping the concepts, but my son is a physics professor -- so I loaned it to him and asked him to explain it to me. He bogged down, so he had his follow faculty look at it and they bogged down. The third book came along, I bought it and waited a couple of months to tackle it, and it gets even more complicated. Again, the "people story" takes a backseat to the physics curriculum. Only in the last hundred or so pages of Arrows does any real tension build through the endless diagrams and proofs and revelations of this universe. And the ending is a gee-whiz tomato surprise.

This is not to criticise Egan (or those readers here who really get this stuff) -- far from that. I've read science fiction for 60 years and can appreciate truly intelligent imagination when it's presented. I just wish Egan would have dialed back the physics lessons and enlarged the very enjoyable depiction of the alien society and how it functioned in a weird but understandable environment. For an example of this I would offer up the first 100 pages or so of Rocket -- very interesting and coherent (and it could be visualized!). I don't know if I'll be reading any more Egan but my hat's off to those who do.

3.0 étoiles sur 5 Fantastic trilogy with a weak conclusion 10 septembre 2014
Par Christopher Lewis - Publié sur
Format:Format Kindle|Achat vérifié
Overall I think the Orthogonal series was fantastic. It's mind-blowing enough that Greg Egan worked out all the physics for a universe completely different from our own. On top of that he wove a compelling alien culture and an allegory of women's rights with strong characters, all too rare in science fiction!

That said, this final entry in the trilogy is the weakest of the three. The whole book felt rushed, particularly the ending which came out of nowhere and basically amounted to "everything worked out fine". And the physics really went crazy here, in sometimes silly ways, although I suppose it would have to after all the buildup!

Altogether I'm really glad I read this series, but the ending could have been stronger.

5.0 étoiles sur 5 it's nice to be exposed to an interesting theory 25 septembre 2014

I waited a long time for this book to become available. While I don't understand all the physics, it's nice to be exposed to an interesting theory. The real story however is one of high drama and interesting characters and there is nothing in science fiction more alien than this trilogy. I think it's a must read.
4.0 étoiles sur 5 A pretty good conclusion to the series 11 novembre 2014
Par B.Keeler - Publié sur
Format:Format Kindle|Achat vérifié
Overall, I really enjoyed this trilogy. In the first novel, Egan introduced a universe with rather different physics, and an alien race with decidedly different biology. Faced with an existential threat, they feel they need to buy themselves some time to come up with a solution. They hit upon an audacious plan to turn an mountain into a spaceship and accelerate it to infinite velocity (there is no cosmic light-speed limit in this universe) thus turning their 'arrow of time' orthogonal with respect to their home world.

The first novel deals with introducing the new physics and new biology, defining the threat and the beginning of the voyage. The second picks up a generation or two after the first and explores new aspects to the physics as well as a social revolution relating to birth control.

The third plays with the notions of time-travel and causality. Many other science fiction authors have explored this area, but Egan still managed to introduce some fresh ideas. The travelers have the opportunity to construct a device which enables them to receive messages from their future selves, but the idea is politically polarizing. About half of the book is concerned with the adventures of a small group of dissenters who want to see if it is feasible to colonize a world whose time arrow is running backwards.

The ending is, as others have pointed out, the one really weak spot. Given the nature of the overall story arc it's inevitable that the conclusion would be something of a deus-ex-machina. "We're back, and here's how we're going to save you." I'm not sure how Egan could have fixed this problem. I wanted to hear about the inevitable culture clash between the arch-conservative home-worlders and the socially progressive travelers, but that would necessarily come after the conclusion to the main story. Perhaps an epilogue would have been the right way to do it.

Very interesting treatment of what might happen in a world with time travel. Information again is key to physics.
