To Open the Sky by Robert Silverberg (Sphere, 1977). Cover by Peter Elson
I’m on something of a Robert Silverberg kick. It started when Mark Kelly reviewed Silverberg’s early novel Collision Course for us back in April, one of the first SF novels I ever read, and in a haze of nostalgia I ended up taking an extended look at all six Silverberg novels packaged up by Ace in that magical year of 1977. More recently I’ve been collecting some of his earlier books, and finding all kinds of interesting artifacts, like the 1969 anthology Dark Stars, and the 1967 fix-up novel To Open the Sky, assembled from five novelettes originally published in Galaxy magazine.
To Open the Sky is the saga of two religions that emerge in the 21st Century, both of which worship technology and atomic power. Over nearly a century the mysterious origins of both religions, and the secret ambitions of their founders, are gradually revealed. It’s the kind of epoch-spanning, tech-focused SF that isn’t written any more. Here’s an excerpt from my favorite review, a short but insightful piece by Thomas M. Wagner at sff180.
A fine example of pre-1970s Bob Silverberg, To Open the Sky is the absorbing story of an overpopulated and economically depressed world clinging to the outcome of a religious schism for its salvation. But is the schism itself a pure public relations ploy, a staged affair whose intricacies are known only to its elusive and enigmatic founder?…
Silverberg effectively constructs a narrative on an epic scale — nearly a century of time between 2077 and 2164 — within a taut 200 or so pages, demonstrating once again that the present-day tendency towards bloat in SF and fantasy publishing is not necessarily the only way to convey big ideas set against a big canvas. Noel Vorst is the founder of a new religious movement rooted squarely in science. Though there is plenty of spiritualist window dressing to appeal to the emotional needs of the disaffected, the promises of the Vorsters are materialist to a fault. There is the promise of potential immortality, as well as the ultimate colonization of the stars, both unfulfilled so far due to limitations of technology.
