The original device proposed by Harold White after finding the energy-decreasing possibilities (see theoretical framework) is a modified Michelson interferometer that uses a λ = 633 nm beam from a helium–neon laser. The beam is split into two paths, with the space warping device placed in or near one beam path. The space warp would induce a relative phase shift between the split beams that should be detectable, provided that the magnitude of the phase shift created by the change in apparent path length is sufficient. By using 2D analytic signal processing, the magnitude and phase of the field can be extracted for study and comparison to theoretical models. The researchers first tried to see if the space warping by the electric-field energy of an extremely-high-voltage (up to 20kV) ring (0.5cm radius) of high-κ barium titanate ceramic capacitors could be detected. After the first tests the experiment was moved to a seismically isolated lab due to very high interference that was already caused by people walking outside the room. The first results gained in the new lab showed a vanishing but non-zero difference between charged and uncharged states after signal processing, but this difference remains inconclusive due to still existent external interference and limits in the computational processing. The current goals are to increase sensitivity up to one hundredth of a wavelength and implement the oscilllating field in order to get definite results.[3][4][5][6][7][8][1]
Warp drive research and potential for interstellar propulsion

The NASA research team has postulated that their findings could reduce the energy requirements for a macroscopic spaceship moving at ten times the speed of light from the mass–energy equivalent of the planet Jupiter to that of the Voyager 1 spacecraft (~700 kg)[9] or less.

Excerpts:


Spacetime metric engineering is a requirement for physically recreating solutions of general relativity such as Einstein–Rosen bridges or the Alcubierre drive. Current experiments focus on the Alcubierre metric and its modifications. Alcubierre's work from 1994 implies that even if the required exotic matter with negative energy densities can be created, the total mass–energy demand for his proposed warp drive would exceed anything that could be realistically attained by humans. Other researchers aimed to improve the energy efficiency (see Alcubierre drive: Difficulties), however the propositions remain mostly speculative. Research groups at NASA's Johnsons Space Center and Dakota State University currently aim to experimentally evaluate several new approaches, especially a redesigned energy-density topology as well as an implication of brane cosmology theory.[1][2] If space actually were to be embedded in higher dimensions, the energy requirements could be decreased dramatically and a comparatively small energy density could already lead to a measurable (i.e. using an interferometer) curvature of spacetime.[3]
The theoretical framework for the experiments dates back to work by Harold G. White from 2003 as well as work by White and Eric W. Davis from 2006 that was published in the AIP, where they also consider how baryonic matter could, at least mathematically, adopt characteristics of dark energy (see section below). In the process, they described how a toroidal positive energy density may result in a spherical negative-pressure region, possibly eliminating the need for actual exotic matter




The first results gained in the new lab showed a vanishing but non-zero difference between charged and uncharged states after signal processing, but this difference remains inconclusive due to still existent external interference and limits in the computational processing. The current goals are to increase sensitivity up to one hundredth of a wavelength and implement the oscilllating field in order to get definite results.
