of contact with humanity. The initial plan is to locate and land on a suitable planet in another galaxy. Millions of years would have passed since their departure, and in any case they would be millions of light years from Earth. However, they find the vacuum of intergalactic space insufficient for safety; they must instead travel to a region between superclusters of galaxies to make repairs. They do, but the extremely thinly spread matter is then too dispersed to use for deceleration. They must wait, flying free but essentially without the ability to change course, until they randomly encounter enough galactic matter to decelerate adequately to search for habitable planets. To make the waiting time shorter, they continue accelerating through the galaxy clusters they encounter, more and more closely approaching the speed of light with tau, or

His infallibility doesn't have to cope with essentially unfixable human messes ... I'm the traditional top sergeant. Hard, harsh, demanding, overbearing, inconsiderate, brutal. Not so bad as to start a petition for my removal. But enough to irritate, be disliked, although respected. That's good for the troops. It's healthier to be mad at me than to dwell on personal woes... Lindgren smooths things out. As first officer, she sustains my power. But she overrules me from time to time. She exercises her rank to bend regulations in favor of mercy. Therefore she adds benignity to the attributes of Ultimate Authority.
428:, the duration that is experienced on the non-accelerating Earth may be multiplied by tau to yield the duration experienced on board the ship. Therefore, as Anderson writes, "the closer that comes to , the closer tau comes to zero", and the longer the time that passes outside the ship for a duration inside. The ship in the story intended to attain a tau of 0.015, but as they continue to accelerate beyond the original schedule, it decreases much further. 212:: the crew will spend 5 years on board, whereas 33 years will pass on the Earth before they arrive at their destination. The ship accelerates at a modest constant rate for most of the first half of the journey, eventually achieving an appreciable percentage of the speed of light, and the goal is to decelerate at the same rate during the second half of the journey by reversing the ram scoop fields. However, the 231:
