Actually no, they say Alcubierre's idea requires that yes which is not possible, but they go on to say that tweaking the theory could bring it into
the realm of possibility. That is why and how they can work on the first field test. After tweaking the theory there is no mention of negative energy
being a requirement. Below is the relevant quote from there.
"The only catch: Alcubierre says that, “just as happens with wormholes,” you’d need “exotic matter” (matter with “strange properties”)
to distort space-time. And the amount of energy necessary to power that would be on par with — wait for it — the mass-energy of the planet
So we’re back to “fuhgeddaboudit,” right?
Maybe not. According to NASA physicist Harold White, the energy problem may actually be surmountable by simply tweaking the warp drive’s
White, who just shared his latest ideas at the 100 Year Starship 2012 Public Symposium, says that if you adjust the shape of the ring surrounding the
object, from something that looks like a flat halo into something thicker and curvier, you could power Alcubierre’s warp drive with a mass roughly
the size of NASA’s Voyager 1 probe.
In other words: reduction in energy requirements from a planet with a mass equivalent to over 300 Earths, down to an object that weighs just under
What’s more, if you oscillate the space warp, White claims you could reduce the energy load even further.
“The findings I presented today change [Alcubierre's warp drive] from impractical to plausible and worth further investigation,” White told
SPACE.com. “The additional energy reduction realized by oscillating the bubble intensity is an interesting conjecture that we will enjoy looking at
in the lab.”
