NASA Conjectural Faster Than Light Space Ship

Yeah, I know; I keep posting this and have in several locations; but man, this ship is just too danged gorgeous!

Here is a conjecture from NASA of a Faster Than Light ship:

It is quite beautiful, and I notice the saucer shape, which causes me to ask just how much influence Star Trek has ...

The problem is, though, NASA has no idea how to power the craft; calling for it to be powered by "exotic materials"; meaning a material we've never seen before ....
