The idea of a warp drive taking us across large areas of space faster than the speed of light has long fascinated scientists and sci-fi fans alike. While we're still a very long way from jumping any universal speed limits, that doesn't mean we'll never ride the waves of warped space-time.

Now a group of physicists have put together the first proposal for a physical warp drive, based on a concept devised back in the '90s. And they say it shouldn't break any of laws of physics.

Theoretically speaking, warp drives bend and change the shape of space-time to exaggerate differences in time and distance that, under some circumstances, could see travelers move across distances faster than the speed of light.

One of those circumstances was outlined more than a quarter of a century ago by Mexican theoretical physicist Miguel Alcubierre. His idea, proposed in 1994, was that a spacecraft powered by something called an 'Alcubierre drive' could achieve this faster-than-light travel. The problem is it requires a lot of negative energy in one place, something that's simply not possible according to existing physics.

But the new study has a workaround. According to researchers from the independent research group Applied Physics based in New York, it's possible to ditch the fiction of negative energy and still make a warp drive, albeit one that's maybe a bit slower than we'd like.
