Much of the technology in this book is speculative, but quite a lot of it is based on real ideas and proposals, none of which involve breaking the laws of physics. Space elevators, ballistic launchers, VASIMR drives, even metallic-hydrogen-fuelled rockets and the direct imaging of exoplanet surfaces, are all technologies that have been discussed in the ‘serious literature’ – indeed, some of these concepts are well on the way to being realised.
At the moment we lack a ‘Theory of Everything’, a single, all-enveloping physical theory that would tie together both the behaviour of matter at the grandest of scales – the dynamics of black holes and galactic superclusters – and the smallest, the fizzing, fuzzy realm of subatomic processes. Despite this, we have some promising candidate ideas. We also live in an era of truly exciting experimentation, with projects like the ongoing Large Hadron Collider pushing into energies which may enable competing theories to be tested against each other. It’s too soon to say what the outcome of these studies will be. Perhaps conservatively, I have assumed that the theoretical physics of Eunice’s time is not radically different from our own. However, the breakthrough on Mercury, with its supposed connection to quark-quark interactions and subsequent application as a new form of spacecraft engine, is entirely fanciful – very much ‘made-up’ science.
There is no such world as Crucible, although the star 61 Virginis is believed to have a planetary system, and the presence of an Earthlike world is not yet ruled out. The field of exoplanet research is moving so rapidly that I fully expect to be caught out by observations within the lifetime of this book. But that’s the joy of speculating in a rapidly evolving discipline.
There is a monolith on Phobos, but no one seriously believes that it’s anything other than a slightly unusual (but not all that odd) geological feature. Obtaining close-up images of this long-shadow-casting object will doubtless be a goal for future exploration of the Martian moons. I look forward to seeing what they find.
Two things motivated me to write a science fiction novel in which Africa was the dominant economic and technological power. The first was a simple: why not? I have never been to Africa, but I have no reason to suppose that there is anything that would prevent Africa, or a part of that continent, from assuming global dominance in one or more advanced industries. The second reason, which is rather more personal and heartfelt – and therefore rather more difficult to articulate – is to do with music. In the last five years I have come to love African music and it has formed a great part of my listening during the conception of this book. In particular I would like to mention the amazing Ugandan musician Geoffrey Oryema, who was very much my gateway into a realm of wonderful and surprising discovery. His beautiful song ‘Land of Anaka’, written from an exile’s point of view, conveyed exactly the sense of overwhelming loss that I felt might be shared by space travellers, centuries from now, remembering an Earth to which they could never return.
Which is why I named my central character Geoffrey.
