LIFEPROBE (circa 1983)
LIFEPROBE by Michael McCollum, Copyright 1983 by Michael McCollum,
Published by Ballantine Books.
DISCUSSION
The first page of the novel LIFE PROBE has this statement, "Assuming that it
(a spaceship) has maintained its speed of one-tenth c (c=the speed of light) for the last ten
days...the source is...on the edge of the Solar System...the ship which will
be here in another hundred days!" Based on the known value of the speed of
light and the extent of the Solar System and Earth's position within, is the
previous statement an accurate esitmate of the arrival time of the so-called
ship?
