C-0020 Under review HIGH certainty
Independent recomputation confirms the Van Den Broeck construction IN FULL, correcting C-0013: region IV reproduces to 1% with our closed form, and — under the profile the paper does state (B = alpha(-(n-1)w^n + n w^(n-1)) + 1 with n = 80, E-0032) — the region II sign split also reproduces to 1%: -1.380e30 vs the printed -1.4e30 and +4.865e30 vs +4.9e30 kg, sign boundary w = 0.9815 vs the printed 0.981. C-0013's 'profile-dependence' finding rested on a false premise (the profile was invisible because the canonicaliser strips inline math and, at the time, the extractor missed macro-wrapped equations) and on a C^1 counterexample outside the paper's stated twice-differentiable class. Residual anomaly, unresolved: VDB's printed POINTWISE peak values appear inconsistent with his own stated profile under recomputation, even though his integrated totals reproduce.
Standing our derivation · numerical result · TRL 1 Assumes his stated parameters alpha=1e17, R~=D~=1e-15 m, R=3e-15 m; region II treated as static via x' = x - v_s t at constant velocity, so rho = R3/16pi with K_ij = 0; the three-Ricci derived symbolically from Christoffel symbols for B^2(dr^2+r^2 dOmega^2); two unrelated C2 interpolating profiles standing in for his unstated one Stops applying non-constant v_s, where the region II slice is no longer static and the extrinsic curvature terms return Computed in compute/vdb_pricing.py, tests/test_vdb_pricing.py Note Root-cause chain worth remembering: canonicaliser strips '$n=80$' from prose AND the extractor (pre-PDB-26) missed the macro-wrapped equation, so the profile was invisible to every tool — and 'invisible' was misread as 'unstated'. Two silent gaps compounded into a false published finding.

…ble' that can be used to transport macroscopic objects. A spacetime is presented for which the total negative mass needed is of the order of a few solar masses, accompanied by a comparable amount of positive energy . This puts the warp drive in the mass scale of large traversable wormholes. The new geome…

…ation of the Alcubierre geometry We will solve the problem of the large negative energy by keeping the surface area of the warp bubble itself microscopically small, while at the same time expanding the spatial volume inside the bubble . The most natural way to do this is the following: ds^2 = - dt^2 + B^2(r_s) [(dx - v_s(t)…
