This means that the flight-time was only\naround 200 years.\n\nSo we will revise the figures worked out in the old, out of print \"Quick &\nDirty Guide to the Long Sun Whorl\":\n\n\n\n         OBJECTIVE   SUBJECTIVE\nLEG         TIME         TIME\nboost     10 years      8 years\nglide    880 years    216 years (a 4:1 ratio)\nboost     10 years      8 years\norbit    100 years    100 years\n-----   -----------   ---------\n        1000 years    332 years\n\n(Remember that the boost times are guesswork, but the boosting must be\nrelatively gentle--I was guessing 0.1 gravities.)\n\nNow then, a 4:1 ratio suggests a velocity of around .97c (up a tad from the\nprevious calculations, naturally).\n\n880 years at .97c = 854 light years.\n\nI'm guessing that the boost stages would add 5 light years each.\n\nThe star of the Blue/Green system is thus around 864 light years away from\nUrth.  Not quite a \"light chilliad,\" but rather close.\n\n=mantis=\n\n\n\n*This is WHORL, for discussion of Gene Wolfe's Book of the Long Sun."
