It is amazing this site, Doc E is still alive and has released his entire archive to WKS (our company) to publish. If you want info on the Enzmann Starship or the man who designed it, this is the place. Starships Now! is his passion, still, after decades of suppression by the powers that be. https://www.blogger.com/profile/09690841820558096064noreply@blogger.comtag:blogger.com,1999:blog-5947401611487621681.post-21965526521140817752017-02-08T22:16:34.455-08:002017-02-08T22:16:34.455-08:00If I might ask which image you are referring to?If I might ask which image you are referring to?Moranhttps://www.blogger.com/profile/13534610668635337473noreply@blogger.comtag:blogger.com,1999:blog-5947401611487621681.post-40121971147226158622017-02-07T18:48:06.784-08:002017-02-07T18:48:06.784-08:00Doc E's website: http://enzmannstarship.blogsp...Doc E's website: http://enzmannstarship.blogspot.com/<br /><br />Please credit any images you use. - webmaster M.

I think the rea... Very good points as always, Yoel. I think the real limit on a starships voyage time is probably no more than a few generations, due to the lack of continuity between those who started the voyage and those who finish it. My favourite model is one in which there are two generations aboard, or a the most three, with a relatively small number of colonists. The ship starts out with the second generation as young children, or still unborn. By the time they reach the destination they have grown up and been trained by the previous generation, most of whom have died on old age. This could also prove very good for ensuring that a colony is tabula rasa, allowing it to develop more organically.<br /> Genetic Engineering... I will have to do a blogpost on it at some time. To me engineering an army of clones or super soldiers has always seemed a little far fetched; the real impact is on the civilian world. While currently there is some ground for people to argue against its use on humans, especially in creating 'designer babies' due to our relative lack of knowledge and skill, this will not always be the case. It is a debate that will rage for a long time, I feel. The movie 'In Time' showed similar effects in a society where people do not age; it was impossible to tell how to people are related by sight only. Very few SF authors explore such issues in any depth, and it is often incredible when done well.

The genetic bottleneck is the usual reason given.<br />The concern is that with small group of colonists interbreeding will result with genetically damaged & retarded colonists. But that true to 'normal' humans.<br />Every human have 23 pairs of chromosomes, females have 23 structurally identical pairs and mails have 22 structurally identical pairs.<br />If a human have defect gene in one of his/her chromosome the parallel gene in other chromosome in the pair is backing up. Problems begin when someone inherent from his/her two parents defect gene in both chromosomes, rare in general, common in interbreeding.<br />So, how to avoid genetic bottleneck without piling thousands of colonists?<br />First- a human selective breeding program either it is on a global scale like seen in the movie "Gattaca" or on a small scale for the colonizing could produce 'flawless' human with no defect genes.<br />Second – gene therapy on earth or/and in journey or/and colony could eliminate those genetic diseases.<br />Third – if what ship and colony need is larger gene pool why carry massive 80kg human and not millions of fertilize ovum with the same mass? Such ovum will be implant in artificial womb and/or womb of crewwoman. <br />All in all, combining one or more of the methods could result in a colonizing ship with a few dozens of people on board. <br />Even with fastship that travels close to speed of light and have travel time of a few years, the crew will have the genetic bottleneck problem when starting to colonize the planet. So one or more of the three methods will be needed anyway.<br />Those 3 technologies could create 'verses different from most SF 'verses.<br />In modern time there is a common taboo regarding interbreeding, the source of this taboo is from the results of such ' marry & f**k your sister' are damaged children.<br />But what if future genetic engineering could prevent those results? What's the reason to stick with such dogmas if genetic diseases are a thing of the past? Today people regards those things in disgusting and as an insult to someone (' U know why U so dumb? Cause your mummy & daddy have the same mummy & daddy'). What if those perfect Augment man & women will reject our ways of thinking?<br />Even if there no colonizing spaceship in the 'verse - what will be the impact of those genetic engineering on those norms? Usually SF writers go on total Armageddon: wars between the improved and normal & dictator building an army of clones.<br />I find it more refreshing to read SF raising some good questions rather than an old trope read several times before.<br /><br />Yoel<br />Anonymousnoreply@blogger.com
