You do realize that "warp drive" is not a technological concept but merely the figment of Gene Roddenbury's wife's mind, right?
Star Trek mumbo jumbo tech talk is fun. My all time favorite is alluvial dampers. I imagine the warp engines oozing silt and dirt when things go wrong.

Some very dilligent physicists are working on FTL issues. It isn't impossible, merely exotic.
Yes, I am aware that such does not exist..
Yet, I am confident that given the proper impetus, ( like discovery of an earth like planet close by ) that someone would figure out a way to get us there quickly.. ( if not safely..)
Maybe you should break the news to the folks at NASA...
