Black goo revealed(?)

Maybe already posted somewhere on the forum (if so, please link)… but I think it would be pretty neat if the black goo is simply nano-robots in liquid, programmed to disassemble or realign DNA whatever way you want. The nano-robots could also be used to completely disintegrate a body, like in the beginning sequence at the waterfall. Seeing Prometheus reminded me of one of the X-files episodes: http://x-files.wikia.com/wiki/S.R._819 [img] http://images4.wikia.nocookie.net/__cb20090909170515/x-files/images/thumb/1/1e/Walter_Skinner_dies.jpg/200px-Walter_Skinner_dies.jpg [/img] Would the robots be self-replicating you could also end up with everything being grey goo: http://en.wikipedia.org/wiki/Grey_goo Bad idea though... What do you think? Thanks for an amazing forum and all interesting posts! Cheers!
