Warp drive...?

Okay, as a break from all the serious stuff...

I like theoretical science, which probably stems from my love for science fiction. This NASA article on theoretical propulsion systems is really really really interesting to me, given that it is one of the few that grounds the discussion in real-world physics - and all without using "I'm-Way-Smarterer-Than-You" scientistspeak. No math, just straight talk on the obstacles involved in the subject of interstellar travel and the reputable research currently underway to circumvent those obstacles.

Nice diversion...
