The Rajan ends by figuring that the Whorl must have been just hanging around in the system for 100 years (detail also matches Pas's planned timeframe, such as we know). This means that the flight-time was only around 200 years. So we will revise the figures worked out in the old, out of print "Quick & Dirty Guide to the Long Sun Whorl": OBJECTIVE SUBJECTIVE LEG TIME TIME boost 10 years 8 years glide 880 years 216 years (a 4:1 ratio) boost 10 years 8 years orbit 100 years 100 years ----- ----------- --------- 1000 years 332 years (Remember that the boost times are guesswork, but the boosting must be relatively gentle--I was guessing 0.1 gravities.) Now then, a 4:1 ratio suggests a velocity of around .97c (up a tad from the previous calculations, naturally). 880 years at .97c = 854 light years. I'm guessing that the boost stages would add 5 light years each. The star of the Blue/Green system is thus around 864 light years away from Urth. Not quite a "light chilliad," but rather close. =mantis= *This is WHORL, for discussion of Gene Wolfe's Book of the Long Sun. --- ### Jim Jordan *10 Aug 2000, 10:12 · follows Michael Andre-Driussi* At 12:25 PM 6/15/2000 -0700, you wrote:> > The star of the Blue/Green system is thus around 864 light years away from > Urth.

Is "light chiliad" from somewhere in the narratives, or just your phrase? My guess would be that a millennium is the least time it could be; perhaps quite a bit longer. Pat.
