Across a Billion Years, Robert Silverberg. New York: Open Road Integrated Media, 2013 (originally published in 1969).
Summary: A group of space archaeologists from different planets make a discovery that puts them on the trail of an ancient, highly advanced race that disappeared nearly a billion years ago.
Tom Rice is a graduate archaeology researcher part of a team drawn from several different races from different planets on an expedition excavating a site on one of the planets occupied by an incredibly advanced and ancient civilization, The High Ones. Tom, in his youthful enthusiasm, is the narrator of this story. The chapters are recorded messages to his telepath sister, Lorie, whose mind can communicate across the galaxy while her invalid body is confined to a hospital bed.
The dig, like most, is tediously routine at first, allowing us to get to know the expedition’s characters–the android Kelly, the rhino-like Mirrick, Dr. Horkk from Thhh, Steen Steen, a hermaphroditic creature, Saul the stamp collector, Leroy Chang, who turns out to be kind of creepy, Pilazinool, who loves to remove and replace his robotic limbs, Dr Shein, who heads the expedition, 408b, an octopoid creature, and Tom’s love interest, Jan, who at first is more interested in the stamp collector.
The expedition shifts from tedium to intrigue when Tom discovers a sphere that is kind of a projector, that plays back scenes from The High One’s civilization. Nothing like this has ever been discovered. More than that, it puts them on a trail of discovery leading first to an asteroid where a robot has been entombed in a cave, it turns out over 800 years ago. They find the asteroid, and the robot intact, who conveniently is a universal translator. The robot in turn takes them to a home planet, abandoned “just” 275 million year ago by the Mirt Korp Ahm, as the High Ones call themselves. The planet continues to be inhabited by a fantastic assemblage of self-maintaining robots, much like Dihn Ruu, their interpreter.
It is here that Dihn Ruu learns why the aging home star of the Mirt Korp Ahm cannot any longer be seen. The planetary system has been enclosed by a Dyson sphere to conserve energy. And with this news, the explorers lay plans to head there, only to face arrest from Galaxy Central!
Will they make it to the home planet of the Mirt Korp Ahm? If they do, what will they find? Will they be received or destroyed? And how will these discoveries change them? These are interesting questions that I cannot answer without spoiling the conclusion.
Perhaps as interesting as this adventure from planet to asteroid to planet are the relationships between the members of the team. Silverberg explores the human-android relationship–are humans from a vat really different from those conceived the old-fashioned way? And why do humans inherently suspect other species?
Equally intriguing is Tom’s perception of his sister. He pities her physical disabilities and “guards” her from aspects of his life that highlight her disabilities. Silverberg gives us an interesting portrayal of how the “abled” view those “differently abled” and how the “differently abled” see things.
Oddly, it seemed to me that what Silverberg considers the least is the encounter between species, and how such contact, particularly if one is far advanced, would change the explorers civilization. Nor does there seem to be much interest in the highly advanced robotic civilization, other than as stepping stones to learn what has become of the Mirt Korp Ahm.
Nevertheless, he raises the interesting question of what a race a billion years old might be like, for humans who reckon the advance of modern civilization over less than 50,000 years. Silverberg presents us with this interesting thought experiment clothed in a chase across a galaxy.
