Name this SF story

From another message board that I frequent, posted by eversbane of that MB:

This sounds like a cool story, but the poster can’t remember the name or author.
The Dope is my best resource to find the truth!

Please help me out here.
Thanks!

Voyage from Yesteryear by James P. Hogan.

It’s also very similar (although not identical) to Frederick Pohl’s story The Gold at Starbow’s End (later expanded to the novel Starburst*) – the crew in that case went aboard as adults, and learn things on board, and society eventually starts breaking down in their absence.

the original novella was nominated for a Hugo, I believe.

*He changed the title , I expect, because he found out “starbows” don’t quite work that way

Five minutes. I love this board!

Adn thanks for the tip - it sounds like a great story.

WOW!

Thank you all so very much.
This would have really bugged me if I could not have found out.
I have never read this, though I am a Hogan fan.

Boy, am I gonna look like a Intrawebz Genious over at the other message board, or what?

heh heh heh

That novel is sitting on my shelf right behind me.
A very ‘far-out’ counter-culture novel.
