Here, it is revealed that DARPA, aka the Defense Advanced Research Projects Agency, is building a quarter-scale test model of a submarine capable of traveling at 100 knots (115 mph). That's fast.
The method by which it does this is it creates a bubble of air around itself and travels through the air bubble, with much lower drag. I'm oversimplifying it, to be sure.
Nevertheless, I had to ask: how long until we build a "warp bubble" and travel inside it at faster than the speed of light?
