And let's face it. I always want to have at least one science and technology topic, and Hey, what happened to Science Discussion? is now too long to be interesting. Well, you can go there and judge it for yourself, if you like.
Anyway, I'm interested in discussing neat stuff like interstellar drives, and computer controled probes, and tactical models that arise from the use of space weapons, and the strategies that those tactics engender in turn, and the relative elements of interstellar commerce, and law, and empire, and whatnot.
I think that we can expect to have unlimited power from fusion before we develop a workable interstellar technology. I say this because fusion technology is within reach given even a modestly serious investment in developing the technology. In fact, the best current interstellar drive technologies, such as ion drives, laser beam propulsion, and the like, cannot be developed without making fusion possible.
<grin>
But, when it comes to the science of interstellar travel, I tend to skip it in my writing since I write characters rather than contemplate science.
I adore science... but of the psychology or biology kind; not heavy metal.
But, I'll read on, MacDuff, no worries there. Did I mention I skip parts of Arthur C. Clarke's work? Maybe I shouldn't....
