I found this article http://dsc.discovery.com/news/2008/0...ed-engine.html which discusses warp drive in which you move space while the spaceship it's self remains stationary. What do you think about it? I'm curious about how they came up with the energy requirements for an inexistent procedure.

It's also the same basic warp drive used by Rodenberry in Star Trek from 1965, so I was never impressed with Michael Alcubierre making claim to it.

You can make a lot of claims, but since you can really build it its all just a bunch of hot air...

It's not new news, either. Miguel Alcubierre's article on warp drive (see http://arxiv.org/abs/gr-qc/0009013 ) was published in about 1994 in Class.Quant.Grav. 11 (1994) L73-L77

Of course, it, like the Krasnikov Tube, it's probably not physically realizable, no matter how pretty the math.

Art also imitates prior art 8-)

Space warps were a useful plot device in books by Asimov, Heinlein, and other writers, who used them before Star Trek. It's nice to know that the basic idea doesn't violate GR, even though a Krasnikov Tube or Alcubierre Bubble requires things like negative energy density....

Let's hope for breakthroughs.
