This is just one article, but they're are plenty more to be found. There is one thing that confuses me though. Alcubierre's warp drive idea seemed to rely on "exotic matter" to bend space time in other words total speculation. So how do we get from that to an actual experiment that uses a laser interferometer to create micro warps? Is this a new application of this technology? It seems like the basis for creating these warps is just as significant as the power reductions, but all the articles I've seen (which are mostly repostings of an article from space.com) gloss over that aspect. Is this just the media hyping something or is there actually something significant going on here?

I'd say that there is a lot of hype going on there, but there could be some potentially useful theoretical physics there too, it's just buried under tonsofhype.
http://www.icarusinterstellar.org/da...eldmechanics/ had a little more. I have no idea of what they might be doing with lasers, though. The closest we've come to exotic matter as far as I know is the Casimir effect. Apparently the paper was presented at some conference, but I haven't been able to track it down. It is an improvement to only need a spaceprobe sized mass of something we don't have than a Jupitersized mass of something we don't have, but unless we actually have exotic matter , it seems like a moot issue.

As I mentioned on the other locked thread, a paper by Harold White (the main guy behind this research apparently) can be found here:
http://ntrs.nasa.gov/archive/nasa/ca...2011016932.pdf And sanman linked to another paper: http://ntrs.nasa.gov/archive/nasa/ca...2011024705.pdf Not sure if some papers on the NASA website are sufficient to meet Physicsforums requirement of published research though (the other thread was locked for a lack of published research, but it's possible the mod just didn't notice these links among all the discussion).
