Ursula K. Le Guin's grasp of science -- like her understanding of human nature -- was not particularly good. To be fair to her, she came out of a ψφ culture that took the admonition against superluminal travel seriously without understanding what it actually meant. The existence of the "ansible" implies time travel just as surely as physically sending a person into the past does, but that idea was one that 1960's science fiction writers [and those who followed after] never seemed to grasp.

Agreed - I was just pulling your chain to see what you’d say ;)

Curious - what is your opinion about Magueijo and Moffat? Charlatanry or something there?
