E.g., see Alcubierre's work. It may well be the the difficulty of making FTL an engineering practicality which is the biggest hurdle.<br /><br />Ad astra! SeanSean M.

Nearest neighbor systems would get information & visitors from just a few years ago & so wouldn't diverge in culture all *that* much if they don't want to. Get light decades or light centuries apart and interesting divergences are inevitable.<br /><br />The almost lightspeed drive of the Kith/Starfarers stories gives something very like what I am talking about, but Anderson couldn't cover all the interesting possibilities.

Because this is the last day of the month and Poul Anderson Appreciation has a round number of posts, 130, I am posting on other blogs but these new posts will be copied here later tomorrow - or even later today if they total 10 before the end of the day.<br />Paul.paulshackley2017@gmail.comhttps://www.blogger.com/profile/17704115766930975286noreply@blogger.comtag:blogger.com,1999:blog-3538502828554372917.post-54718215895354877652017-07-31T15:12:12.562+01:002017-07-31T15:12:12.562+01:00Kaor, Paul!
Besides Anderson's STARFARERS and...Kaor, Paul!<br /><br />Besides Anderson's STARFARERS and Niven's A WORLD OUT OF TIME, I would have included the former's THE LONG WAY HOME. That last mentioned book shows human explorers returning "home" 5000 years after leaving Earth, without them REALIZING their still new and incompletely understood "FTL" drive had not worked as they had thought it would.<br /><br />THE LONG WAY HOME was one of Anderson's earlier novels, and shows it here and there, but I liked it and thought it well written.<br /><br />I'm inclined to think Wells and most of his earliest readers didn't fully understand the implications of the theme he had invented, time traveling. I would not expect pioneers like Wells to fully grasp the consequences of the ideas he came up with. I think later writers like L. Sprague De Camp, Robert Heinlein, Poul Anderson, Ward Moore, etc., would think of those implications and start working out their consequences.<br /><br />Sean<br />Sean M.
