Why has the attitude of generation ships been cast aside? As a result of Earth's final wars mankind had to take to slow generation ships in order to seed the galaxy and survive. After landing on these newly discovered planets, the attitudes regarding generation ships has been discarded because the pressing need has been eliminated. Yet, Haven was an expansionist society. They needed to conquer to survive. Yet why hasn't Haven and the rest of humanity continued to look for new worlds? Those early crude hyper ships were dangerous and less advanced. With present technologies, why hasn't a new era of exploration ships been launched to find new worlds? A generation ship built with hyper technology could cover even vaster distances much faster and incomparably safer than those early ships. And the first crude hyper ships, which were little more than death traps became the earliest forms of survey ships.
It seems this would be the job of current survey ships. But there seems to be so few of them, unless most are simply "gone where no man has gone before" and haven't reported back and the little mention we do hear of any survey ships they seem to be busy putting their talents to searching for wormholes and surveying them.
Also, I came across this on a fan site.
It was Doctor Cadwaller Pineau of Tulane University who, in 305, finally cut the Gordian knot of cryogenic hibernation by going around the crystallization problem. He found that by lowering the hibernator's temperature to just barely above the freezing point he could maintain the physiological processes indefinitely at about a 1:100 time ratio. In other words, a hibernating human would age approximately one year for every century of hibernation, and his nutritional and oxygen requirements were reduced proportionately. Over the next several decades, Pineau and his associates further refined his process, working to overcome the problem of muscular atrophy and other physiological difficulties associated with long comatose periods, and eventually determined that optimum results required a hibernating individual to rouse and exercise for approximately one month in every sixty years (ie., after six physiological months), which remained a fixed requirement throughout the cryogenic colonization era.
How would the effect of prolong work in conjunction with this?
