Thanks for the link - that comment is great.

I gotta quote one line that is just cool, though:

  4. A test at 50 W of power during which an 
  interferometer (a modified Michelson device) 
  was used to measure the stretching and compressing 
  of spacetime within the device, which produced 
  initial results that were consistent with an 
  Alcubierre drive fluctuation.

Which is just really cool. The followup sums up my fascination with the whole thing niceley:

  Test #4 was performed, essentially, on a whim 
  by the research team as they were bouncing ideas 
  off each other, and was entirely unexpected. They 
  are extremely hesitant to draw any conclusions based 
  on test #4, although they certainly found it interesting.

That right there is science in progress: a hint of something interesting, a test leading to another test leading to another, each interesting in their own right. It's still not clear if something spectacular is going on, but I think it's undeniably interesting. Careful reexamination can yeild all manner of useful insights!

(Off topic, but along the lines of closer examination, see https://news.ycombinator.com/item?id=9020065 for how some careful (and extensive!) experimentation helped illuminate sodium's reaction with water. Not just how much work was needed to tease out the details!)
