abstract

The discrepancy between low and high redshift Hubble constant $H_0$ measurements is the highest significance tension within the concordance $\Lambda$CDM paradigm. If not due to unknown systematics, the Hubble puzzle suggests a lack of understanding of the universe's expansion history despite the otherwise spectacular success of the theory. We show that a G\"odel inspired slowly rotating dark-fluid variant of the concordance model resolves this tension with an angular velocity today $\omega_0 \simeq 2\times 10^{-3}$~Gyr\textsuperscript{-1}. Curiously, this is close to the maximal rotation, avoiding closed time-like loops with a tangential velocity less than the speed of light at the horizon.

  1. Extended uncertainty principle inspired black hole in a G\"odel Universe

    gr-qc 2025-05 reject novelty 4.0 of 10

    A Godel-rotation-modified uncertainty principle is used to define a corrected black hole mass, producing enlarged horizon, shadow, and deflection with lower bounds a/M ~ 10^5 from EHT and PPN data.
