Speed limits in general relativity
Open accessAbstract
Some standard results on the initial value problem of general relativity in matter are reviewed. These results are applied first to show that in a well defined sense, finite perturbations in the gravitational field travel no faster than light, and second to show that it is impossible to construct a warp drive as considered by Alcubierre (1994 The warp drive: hyper-fast travel within general relativity Class. Quantum Grav. 11 L73-7) in the absence of exotic matter.

Generic Natário warp drives are known to violate the dominant energy condition (DEC).
“Generic Nat´ ario warp drives are known to violate the dominant energy condition (DEC) [15]”
From Generic warp drives violate the null energy condition (2022) · cites this paper as [15]
Section 4 (p. 6) argues that an effective warp drive requires matter that violates the dominant energy condition under its stated assumptions about matter-field evolution. The paper does not discuss Natário warp drives or establish that generic members of that specific class violate the condition. (LLM, conf=0.86)

“It therefore follows that a warp drive can only be constructed in the presence of exotic matter, confirming the suspicion voiced in Alcubierre (1994).”

“(5.30) DEC: One version of the DEC, as reported by Hawking and Ellis [42, page 91], is formulated as the requirement that in any orthonormal frame the energy density dominates all the other components of the stress-energy tensor: |T âb̂| ≤ T t̂t̂.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
