Skip ahead to this month, where we have a propulsion device that somehow produces microwaves to generate thrust. According to posts on NASASpaceFlight.com, someone at NASA wondered where the thrust came from and used a tool to measure variances in light's path-time. What this tool recorded is that when lasers are fired through the EmDrive's resonance chamber, some of the beams start moving faster than the speed of light. If everything checks out - and on the surface the math does - it means the EmDrive is producing some kind of warp field.
These claims appear to be independent of previous claims that NASA was working on a warp drive. Additionally, the EmDrive appears to have largely been met with skepticism and over on the Physics Stack Exchange site the physics also appear to debunk the drive as well.
As such, are these claims groundless and has there been any official response from NASA yet?
