Of direct importance to the advanced super-technology of warp drive and wormhole star gates from our alleged visitors from our own future is the problem of classical curvature singularities in Einstein’s 1916 battle-tested standard geometrodynamics of the gravitational field.

“Together with the great theoretical and experimental successes of Einstein standard geometrodynamics, come two main conceptual problems.[i] First, the theory predicts the occurrence of spacetime singularities, events which are not part of a smooth spacetime manifold,[ii] where usually the curvature diverges and where the Einstein field equation and the known physical theories cease to be valid. Second, Einstein’s theory of gravitation, unlike the other fundamental interactions, has not yet been successfully quantized.”

Einstein’s 1916 classical GR geometrodynamics in the weak field first order perturbation approximation against the non-dynamical globally flat Minkowski spacetime of his 1905 special relativity has “achieved an experimental triumph” with “direct confirmations” of gravitational time dilation, gravitational bending of light (lensing), lunar laser ranging, de Sitter geodetic effect, GPS. Transverse polarized far field gravity waves have been indirectly detected from the orbital energy loss of binary pulsar PSR 1913 + 16. Gravimagnetism, a very weak effect, has recently been measured in NASA’s Gravity B space experiment.

“the concept of gravimagnetic field generated by mass currents, in partial analogy with electrodynamics, … its measurement of the dragging of inertial frames” constitutes “direct experimental evidence against an absolute inertial frame of reference and … experimentally displays the basic role in nature of the local inertial frames.” [iii]

[i] Enrico Rodrigo’s Stargate book updates the singularity problem and shows that there are now several ways of dealing with it since the classical energy conditions assumed by Penrose and Hawking are actually false in quantum theory. The discovery of anti-gravity dark energy accelerating the space expansion of our observable universe (aka “causal diamond”) also is a game changer.

[ii] My “Destiny Matrix” conjecture that we live inside of a hologram conscious computer simulation has the “brane of GOD(D)” (I. J. Good’s “superluminal telepathic” cosmic consciousness) at our future de Sitter event horizon of asymptotic area-entropy A. The dark energy we see now in our past light cone is actually gravitationally redshifted back-from-the-future (as in Yakir Aharonov’s post-selected destiny quantum wave and John Cramer’s TI) Wheeler-Feynman Hawking black body gravity wave radiation from the Planck length thickness of that future horizon. The surface of the horizon is discrete pixelated into quantum area bits whose images are voxelated quantum volume bits of what Hagen Kleinert calls the World Crystal Lattice. However, the 3D lattice spacing is only Fermi 10-15 meters not the 2D lattice pixel spacing of 10-35 meters. The problem here is that we need w = pressure/energy density < - 1/3 for dark energy, whilst blackbody radiation has w = +1/3. This is because of the Einstein factor (energy density)(1 + 3w) in the stress-energy current density source of his geometrodynamic field equation. When w < - 1/3 the positive energy density giving universally attractive gravity switches over to the “exotic matter” regime of universally repulsive antigravity, which stops the crunch to oblivion of the black hole singularity. Now it may well be that back-from-the-future advanced Hawking radiation does have w < - 1/3 from the kinds of EPR correlations that Lenny Susskind talks about that cause deviations away from the Planck black body spectrum preserving the unitarity of the S-Matrix of the world. This is still, speculation of course. Another approach is the Unruh effect, which says w = -1 random zero point quantum vacuum fluctuations seen in LIFs morph to w = +1/3 black body radiation in a coincident LNIF and vice versa. The effective LNIF that we see in our detectors has a Hawking temperature that when raised to the fourth power according to Stefan-Boltzmann’s law gives the correct number measured for dark energy density in the anomalous redshift data from Type 1a supernovae.

[iii] The recent book Making Starships by James Woodward (Springer-Verlag) proposes a theory with an actual experiment based on Dennis Sciama’s 1950’s “vector theory of gravity”. I consider this model to be ill-posed, too simplistic, and from what I can understand of it, it presupposes an absolute inertial frame that conflicts with the gravimagnetism of Einstein’s GR.
