abstract

A new final state of gravitational collapse is proposed. By extending the concept of Bose-Einstein condensation to gravitational systems, a cold, dark, compact object with an interior de Sitter condensate $p_{_V} = -\rho_{_V}$ and an exterior Schwarzschild geometry of arbitrary total mass $M$ is constructed. These are separated by a shell with a small but finite proper thickness $\ell$ of fluid with equation of state $p=+\rho$, replacing both the Schwarzschild and de Sitter classical horizons. The new solution has no singularities, no event horizons, and a global time. Its entropy is maximized under small fluctuations and is given by the standard hydrodynamic entropy of the thin shell, which is of order $k_{_B}\ell Mc/\hbar$, instead of the Bekenstein-Hawking entropy formula, $S_{_{BH}}= 4\pi k_{_B} G M^2/\hbar c$. Hence unlike black holes, the new solution is thermodynamically stable and has no information paradox.

  1. Self-Forces as Nonlocal Probes of Gravastar Interiors

    gr-qc 2026-07 conditional novelty 7.0 of 10

    Static scalar and electric charges near a thin-shell gravastar experience self-forces different from those near a black hole, with analytic leading-order formulas.

  2. Regular Vaidya solutions of effective gravitational theories

    gr-qc 2025-06 unverdicted novelty 7.0 of 10

    Regular Vaidya solutions exist in effective gravitational theories that dynamically describe radiation-driven formation of regular black holes or mimickers without curvature singularities.

  3. The macroscopic precession model of quasi-periodic oscillations for rotating compact objects

    gr-qc 2026-07 conditional novelty 6.0 of 10

    Treating QPO-emitting disk clumps as spinning test bodies reproduces the observed twin kHz QPOs without the effective de Sitter term, with fits preferring n≈2 thin-disk structures for Schwarzschild and n≈1 for Kerr.

  4. Gravitational Properties of the Monopole Bag

    hep-ph 2026-04 unverdicted novelty 6.0 of 10

    Monopole bags in axion models can collapse into horizonless objects or dyonic regular black holes that evade singularities and retain axionic structure through Chern-Simons effects.

  5. Reflectionless and echo modes in asymmetric Damour-Solodukhin wormholes

    gr-qc 2025-11 unverdicted novelty 6.0 of 10

    In asymmetric Damour-Solodukhin wormholes, reflectionless and echo modes share asymptotic spectral properties parallel to the real frequency axis with matching spacing, and reflectionless modes lie closer to the axis ...

  6. Thermodynamics in space-times without horizons

    gr-qc 2025-07 conditional novelty 6.0 of 10

    Zero-energy timelike junction surfaces in static spherically symmetric spacetimes are shown to have area-proportional entropy and a temperature set by their transverse pressure.

  7. Horizon formation from effective matter profiles in static spacetimes

    gr-qc 2026-05 unverdicted novelty 5.0 of 10

    Sufficient conditions are given for a unique outer horizon to cloak a negative-mass Schwarzschild timelike naked singularity when non-negative localized anisotropic matter is added.

  8. Tests of General Relativity with GW230529: a neutron star merging with a lower mass-gap compact object

    gr-qc 2024-06 conditional novelty 5.0 of 10

    Parameterized inspiral tests on GW230529 find consistency with GR, with |δφ̂_{-2}| ≲ 8×10^{-5} and ℓ_GB ≲ 0.51 M_⊙ in ESGB theories.

    gr-qc 2026-08 reject novelty 4.0 of 10

    A propositional model predicts that the coupling parameter of f(R, L_m, T) gravity shifts the inner edge of a gravastar accretion disk and that surface emission could fill in the central shadow.

    A sparse population of primordial charged compact objects is hypothesized with specific parameters and shown to face severe plasma-screening and neutralization constraints while failing to produce late-time accelerati...

    The paper provides state-of-the-art predictions for the Einstein Telescope's impact on fundamental physics, cosmology, compact-object astrophysics, and multi-messenger astronomy across its proposed configurations.
