Engines for the High Frontier

We want engines to get us into space and take us to the stars. Of course, as many note, we aren’t quite where we want to be yet. But there is hope. At the moment, spaceship engines can be classed into three categories: rockets, sails, and “other,” and each works in their own, individual way. Rockets work by pushing something out the rear; reaction equaling action, you go in the other direction. With sails, something external pushes. And in the “other” category are things like “space drives” and ramjets.

A few years back I was working on a project to look at the feasibility of interstellar probes. I arrived at this conclusion: the real key to any sort of a probe that could reach nearby stars using propulsion technologies which we could plausibly see in the near future was that the probe itself had to be as small as it could possibly be. That led me to a lot of thinking on the order of how small could you really go. How sophisticated could you actually make a small spaceship?

Future Weapons

Ray guns! Death rays! The terms conjure images of the golden era of space adventurers—Buck Rogers, Flash Gordon. But in truth, future weapons have been a crucial aspect of science fiction since H. G. Wells armed his Martian invaders in War of the Worlds with heat rays that ignited everything in their path.

I ended up first with Arighan’s Flower, because I figured wiping out whole ancestral lines would be a pretty big threat. I also knew from the beginning that I wanted the gun to be one of a set. … One of my beta readers actually wanted this story to be about five times as long as it is right now, and to follow that kind of structure, detailing Shiron’s adventures with each gun. Quite probably it would have been a good story, but it wouldn’t have been the story I wanted to tell.

Cyborg-netics

Long before the premiere of The Six Million Dollar Man in 1974, the idea of a bionic human has fascinated the scientific and science fiction communities. Just turn on the television or take a trip to the local movie theater to find some examples. But there’s a lot more to this burgeoning science than Darth Vader and the Borg. It’s not just science fiction; it’s not even science future. What most people might be surprised to discover is that the kinds of mechanized prosthetics writers used to dream about actually exist right now.

Published in 1985, “More Than the Sum of His Parts” was set in the then-distant future of 2058. “It seemed a reasonable time frame, when we were somewhat more optimistic about space industrialization,” Haldeman says, “although the waldo technology is wishful thinking, or arm-waving—I didn’t have any actual technological rationale for it happening that soon, or ever. The waldos themselves were inspired by the story ‘Waldo,’ by Robert Heinlein. The idea of smaller and smaller waldos building their miniaturized successors came from the notions about self-replicating ‘von Neumann’ machines that were cutting-edge techno-dreaming at the time.”

Interview: Robert J. Sawyer

“What intrigued me was that SF—especially in film and TV—had taken as a given that future AI will be malevolent, and that there’s no way for humanity to survive the advent of things more intelligent than we are. Well, SF is supposed to be about offering choices for tomorrow—and if we don’t have a positive blueprint, then the negative one becomes a self-fulfilling prophecy.”

This is a post-poverty utopia where everybody lucky enough to be plugged into the society’s opportunities—the passengers or if you prefer “pilots” of the arvies—gets to do whatever the heck they want to do with their lives, indulging their slightest whims via the bodies whose wombs they occupy. I left unexplained what criteria determine who gets to enjoy all of this world’s vast opportunities and who becomes an enslaved recreational vehicle; that decision is made, from standards you and I can only guess at, long before any fetus is granted the gift of adult awareness. There must also be genetic and medical issues involved far beyond us. But no doubt, if some zygote possesses genetic gifts that promise vast talent in athletic pursuits, that’s a quality that would render their future body very very much in demand as athletic gear for some fetus interested in enjoying the ride from the safety of the amniotic fluid.
