  • Greetings
    I am a hard science fiction fan but the science really has to work for me. So far so good but you are skating on the edges. I subscribe to both Analog and Magazine of Science fiction and fantasy. With Stan Schmidt gone I have renewed hope for Analog after about 30 years

    . Would you consider the Ring World series by Niven”Hard SF”?

    • Hi, thanks – the Ring World is very well thought out but it features FTL travel and teleportation which I consider impossible. So no Hard SF for me.

  • FTL travel is likely not possible with the physical laws of the universe being as they are, and as we understand them today. However there are other possible ways to skin that cat. Time is relative – Gregory Benford explored the ramifications of travel near a high fraction of the speed of light, for both the crew aboard the craft (time passes more slowly) as well as for those left behind. I believe Larry Niven also spoke to the downside of near-C travel, as one approaches the finite speed of light, one’s mass would also increase by a like factor. So a vessel traveling at, say 99% of the speed of light may well destroy any planetary system as one passes by, perhaps by even a few light years distant.

    • I am sure that Niven was wrong. I had a long explanation but don’t want to get into an argument. To my mind FTL and coherent time require a wall preventing travel into the past. Like Hawking’s feedback loop where approaching entranceways to time travel blow-up. FTL does imply time travel/communication unless the universe objects; like a fire-wall/explosion at the last link. Actually Forward had a book (“Master of Time” I think) that handles time travel coherently. But then the Universe is filled with “coincidences”; one has to think a long time, but that is the only way you can have time-travel and a coherent time-line.. One alternative is Hawking’s blowup; another is Gibson’s new series of just branching histories. I am studying the Kerr Metric though and the mathematical extension has time-travel embedded in it; you just don’t get to see it 🙂 Hidden from the outside 🙂 Actually, I don’t believe that extension is correct/consistent with the possible physics but haven’t got to the point of proving it wrong;; although I have a lot of opinions ::)

  • I do have one complaint about the book “The Dark Spring”. I never noticed how the little probe got the power to xmit back to earth. The rest made reasonable sense.
