Let's make one thing very clear, this is not confirmed. In fact, it's about as confirmed as the title of the next Star Trek film which is, as you may know, unconfirmed.
NASA has been experimenting with a revolutionary new propulsion system called the EmDrive and after some preliminary analysis there's some evidence that it is actually creating a warp field.
According to the NASA Space Flight forum it was discovered that when lasers were fired into the EmDrive's resonance chamber, some of the beams were travelling faster than the speed of light.
If true, then it would mean that the EmDrive is producing an actual warp field or 'warp bubble'. Now it's important to remember at this stage that this is simply a prediction.
The team who have built the EmDrive are still working on a method to categorically prove that this is true. However, if true it'll be a small but significant step in the long road to interstellar travel.
No, we won't be saying 'engage' anytime soon, but what this news tells us is that at some point in the future someone just might.
