> I did some research for NASA looking into such "negative mass solutions" in M-Theory that arise as a result of hep-th/9507022. Cool! The most informative thing about that to me is simply the knowledge that NASA has a history of investigating this sort of thing. Maybe it's a good thing if they keep a trickle of resources pointed in that direction, just in case there's something really there to be found. I hope they've got good people assessing whether it's worth it. (It's still odd for that sort of speculative work to be getting substantial press attention, though.)
