#2> The only problem is, previous studies estimated the warp drive would require a minimum amount of energy about equal to the mass-energy of the planet Jupiter.
Uh, no. The "only problem" is that the concept relies on exotic matter, a hypothetical matter with 0 evidence for its existence (so far). See http://en.wikipedia.org/wiki/Exotic_matter

Well, the Casimir effect generates a tiny amount of negative energy, does it not? Maybe that's how they think they can test it in the lab.

That was my main problem with this article. http://en.wikipedia.org/wiki/Exotic_matter You could simulate the effect using metamaterials probably, but you couldn't break the real speed of light with it because you don't have real negative mass.

Actually the Casimir effect just reduces the "ambient" pressure, it doesn't create negative pressure. http://en.wikipedia.org/wiki/Casimir_effect
Edit: Whoops, looks like it might work anyway http://en.wikipedia.org/wiki/Casimir_effect#Wormholes
Edit2: Actually I think that contradicts this http://en.wikipedia.org/wiki/Wormhole#Raychaudhuri.27s_theor... which makes more sense to me. Unless you have already curved spacetime, a Casimir effect is not enough to stabilize a wormhole.

Got to start somewhere if we want a shiny starship

#9Warp speed is only 1/10th the speed of light.
As far as some news about faster than light travel, refer to: http://xkcd.com/955/

#10As much as it pains me to say this, but I think we have to invent some more advanced weapons before we start poking our heads out of our galaxy. Don't get me wrong, this is fantastic and I'm all tingly from excitement (this is the first time I've read about warp drives in the context of real science) ... but like I said, taking a stroll trough the galaxy with our bombs and finding a hostile alien world. Well we'd be screwed.
Just food for though here; this is from the Halo universe, where the timeline goes something like this: humans invent "warp drives", they colonize other worlds, soon this colonies start to rebel which leads to a massive space civil war. Later the aliens arrive and set to destroy all of humanity. Now, if it waren't for the civil war, humans would have no experience in space combat, and they wouldn't have developed more advance weapons which would later allowed them to defeat the alien threat.
