Astronomers have certainly observed things that are small, dark, and heavy. But are these objects really black holes in the sense of general relativity? The consensus opinion is simply "yes", and there is very little "wriggle room". We discuss one of the specific alternatives.

  1. Self-gravitating thin shells are dynamically unstable on all angular scales

    gr-qc 2026-04 unverdicted novelty 6.0

    Self-gravitating thin shells in general relativity are dynamically unstable on all angular scales, exhibiting an exponentially growing mode for all sampled compactness, adiabatic index, and multipole order ℓ ≥ 2.

  2. Testing the nature of dark compact objects: a status report

    gr-qc 2019-04 accept novelty 2.0

    Current and future observations can test whether dark compact objects are Kerr black holes or exotic alternatives, with null results strengthening the black hole paradigm.
