We review the status of "Einstein-Aether theory", a generally covariant theory of gravity coupled to a dynamical, unit timelike vector field that breaks local Lorentz symmetry. Aspects of waves, stars, black holes, and cosmology are discussed, together with theoretical and observational constraints. Open questions are stressed.

Discussion (0). Continue with ORCID to comment.

  1. Tests of scalar polarizations with multi-messenger events

    gr-qc 2026-04 unverdicted novelty 6.0 of 10

    Bayesian analysis of GW170817 with PPE framework and EM polarization constraints shows mild preference for scalar mode in quadrupole harmonics and improves bounds on non-GR parameters by up to 60%.

  2. A no-go theorem in bumblebee vector-tensor cosmology

    hep-th 2025-09 conditional novelty 6.0 of 10

    Bumblebee gravity with non-minimal couplings is healthy only under the degeneracy σ=-ξ/2, which fixes the potential and yields a stealth de Sitter solution with scalar sound speed squared ≈1/6.

  3. Lorentz Violation with Gravitational Waves: Constraints from NANOGrav and IPTA Data

    astro-ph.CO 2025-05 conditional novelty 6.0 of 10

    Using NANOGrav 15-year and IPTA second data release, this paper sets a 68% confidence lower bound of 10^-19 GeV on the Lorentz-violating scale M_LV in a modified gravity model.

  4. How black hole mimickers and Shapiro-free lenses signal effective dark matter

    gr-qc 2025-04 conditional novelty 6.0 of 10

    Two new exact solutions in aether-scalar-tensor gravity describe a black-hole-mimicking wormhole and a massless lens with negative Shapiro time delay.

  5. Gravitational radiations from periodic orbits around Einstein-\AE{}ther black holes

    gr-qc 2025-05 reject novelty 4.0 of 10

    The authors present periodic orbits and quadrupole gravitational waveforms for a test mass around two Einstein-Æther black hole solutions, and claim observable æther-induced waveform changes.

  6. Conserved charges and asymptotic symmetries of BTZ-like black holes in Einstein-bumblebee gravity

    hep-th 2025-04 conditional novelty 4.0 of 10

    For BTZ-like black holes in Einstein-bumblebee gravity, the conserved charges, central charges, and entropy all acquire factors of the Lorentz-violating parameter, and the near-horizon extremal case admits a Virasoro-...
