Interstellar Travel: Difficult, yes; Impossible; No - NASA

"Warp Drive, When?"
NASA

(moved, also at "www.nasa.gov/centers/glenn/technology/warp/warp.html)

"Have you ever wondered . . .
When can we build something like the futuristic spacecraft shown above?

"Have you ever wondered when we will be able to travel to distant stars as easily as in science fiction stories? NASA Glenn's Marc Millis (pictured above), who has taken a break from Project Management for NASA's Breakthrough Propulsion Physics (BPP) Project to return to conducting research, offers this assessment of the prospects for achieving the propulsion breakthroughs that would enable such far-future visions of interstellar travel."

An imaginative and realistic look at what sort of interstellar travel is - and might be - possible.

This could be a good resource for a serious science fiction writer.
