Lentz soliton has a "delta" shape formed from about sevenĭiamond-shaped blocks of specially-configured ADM shift vectors "flying inįormation" to surround the flat interior region and to move it forward. With the speed of the soliton itself without feeling inertial forces. Outside time (i.e., no relativistic time dilation), and internal observers move Region with minimal tidal forces, in which internal proper time corresponds to His soliton is constructed to contain a relatively flat-space central Superluminal, soliton that involves only positive mass-energy. "shift vector", Lentz has been able to construct a moving, possibly Relativity and a hyperbolic rather than linear or elliptic relation for the ADM Using the Arnowitt, Deser, and Misner (ADM) formulation of general Space-time soliton solution of Einstein's equations of general relativity. ) has demonstrated that there is a positive-energy 's Göttingen University Institute for Astrophysics (and who received his PhD in Particles in our universe, but they have never observed any at all.Ī recent paper, Dr. Technology to produce even that relatively modest amount of negativeĪnd astronomers have conducted searches for negative- (and even imaginary-) mass That's much better, but the problem remains that we do not have the Reduced to about a ton of negative mass-energy.

However, the magnitude of the negative mass-energy needed by the original To the suppression of long-wavelength vacuum modes, i.e., waves too long to fitĬreate a thin region containing a small bit of negative energy.
