Where did Warp 3 in the original series is 27 times the speed of light come from? In the book The Making of Star Trek page 191 it states that Warp Factor 3 is 24 times the speed of light. Which one is correct?

I've recently finished Count Zero and I admit I have no idea of what the ending lines mean. I'm not an english native speaker but I went through the whole book with no major issues, apart from searching a few words here and there, so I'm not sure I could blame the language. The ending lines for t...

I'm trying to find a novel I read a long time ago and it's driving me nuts - all Google searches result in failure..it's been 10-15 years since I've read it I think, here's some details I remember: The biggest plot twist is that the main character is being told that he's on an exact replica of e...

Basic beginning premise is that a young man, who I think was trained in swordsmanship, finds a magical artifact capable of absorbing energy/magic at the cost of his life/vitality. He's able to extend this ability to his weapons. Setting is high fantasy, and the big bad is someone trying to collec...

We have a question about who was the last elf in the Middle Earth and about elvish children. This is about the continuity of family trees. The family trees seems very well established. It appears as if all elves are adults. However, checking the answers to the 2nd linked question, it seems like e...

When I was a kid, I had an anthology of sf stories, and now I'm trying to see if I can recover/rediscover any of them. The book itself was a hardback. I read this as a kid, so some time in the 90s. But it's quite probable the book itself was quite a bit older (maybe from the 70s or 60s). Here are...

I am curious. Why are the hallways in a lot of sci fi movie and video game octagonal? Below shows a Google search for "futuristic sci fi hallway" Like this: Is this just to make the hallways look high-tech and "spacey", and/or are there actual engineering and design reason for this?

When I was a kid I remember watching a sci-fi movie or a TV series (likely to be a movie) with very vague memory like this: several teenagers (or adults) running on a beach and then one of them fell in a tunnel and started falling for a while, meaning the tunnel was quite long. The tunnel was in ...

I saw a part of this while channel-surfing around a few months ago on Comet TV, and it's been bugging me ever since that I couldn't place it. Today, I snap and present the challenge to SFSE. Here is everything that I can remember: The movie appeared to be entirely cast by Asian actors and presum...

There's a book I borrowed from my Grade 8 teacher's lending shelf (in Ontario, Canada) that I've been trying to identify for years. The main character was a man in a futuristic setting who... I think... had the secret to an improved version of the lifespan-extension serum everyone used. If I reme...

I'm trying to identify a novel for young adults about travelling through time using a maze of time tunnels. I borrowed it from the Town Library in the early 1970's, so it may have been written during the late 50's or early 60's. I think it's set in the North of England, possibly Newcastle. Two te...
