Science fiction writer Charles Stross, always an insightful voice when it comes to the future of technology, offers up an incisive look at the problems of interstellar flight in his The High Frontier, Redux. The article is in the queue for discussion here, but since I can’t get to it until tomorrow afternoon — and since comments are already flying about what Stross has to say — I’ll set up this topic as a gathering point for those comments until the larger post goes online. Read Stross when you can, as anyone seriously interested in interstellar possibilities needs to understand the magnitude of the challenge. We’ll run through some of the issues tomorrow, and look at one Stross comment I find completely puzzling.
