Parsecs

There was a groan in the audience at an sf con when a "parsec" was cited as a unit of speed, not of distance, in Star Wars.

In Poul Anderson's World Without Stars, the spaceship, Meteor, leaves the rim of the galaxy:

"...we were going two hundred and thirty thousand light-years away." (V, p. 28)

Having reached their target planetary system in intergalactic space, the crew sees the galaxy:

"...across seventy thousand parsecs." (VII, p. 43)

So 230,000 light years = 70,000 parsecs?

1 light year = 3.28 or so parsecs?

Live and learn or, at least, read Poul Anderson and learn. I find it impossible to progress reading the book without stopping to post about a detail or going off at a tangent.

Kaor, Paul!

And I sympathized with the exasperated audience groaning at that maddening blooper made in that STAR WARS movie! A parsec is a unit of DISTANCE, not speed. All LITERATE science fiction fans would know that! This kind of nonsense is one big reason why I dislike most TV and filmed SF.

I really long for a good, accurate, filmed version of some of the Nicholas van Rijn or Dominic Flandry stories!
