In 2012, NASA physicist Harold White revealed that he and a team were working on a design for a faster-than-light ship. Now he's collaborated with an artist to create a new, more realistic design of what such a ship might actually look like.
Artist Mark Rademaker told io9 that he worked with White to create the updated model, which includes a sleek ship nestled at the center of two enormous rings, which create the warp bubble.
In this video, below, you can see White talking about the new design (starting at 41:54), and explaining how it fits his mathematical analysis.
You can see more incredible images of the ship from Rademaker in his Flickr gallery.
