Based on a relation between inertial time intervals and the Riemannian curvature, we show that space--time uncertainty derived by Ng and van Dam implies absurd uncertainties of the Riemannian curvature.

  1. Salecker-Wigner-Karolyhazy Gedankenexperiment in light of the self-gravity

    gr-qc 2019-08 conditional novelty 5.0 of 10

    A heuristic argument that a clock's own gravity stops its wave-packet from spreading, reducing the minimum length-measurement uncertainty from the Karolyhazy scale l_P^(2/3) l^(1/3) to the Planck length.
