Dark bubble cosmology is an alternative paradigm to compactification, which can circumvent issues of moduli stabilization and scale separation. In this paper we investigate how electromagnetic fields can be incorporated in this framework. Worldvolume fields backreact on the ambient universe in which the bubble expands, which in turn affects the energy-momentum distribution and the effective gravity induced on the brane. We compute these effects, showing that the resulting four-dimensional cosmology consistently includes electromagnetic waves.

  1. Weak gravity at micron scales from dark bubble cosmology and its cosmological consequences

    hep-th 2025-11 conditional novelty 7.0 of 10

    Dark bubble cosmology predicts gravity weakens below L~10^-5 m, yielding V=-G4M(1/rho - 3L^2/(2rho^3)+...) and a radiation-only inflationary phase.

  2. Dark bubble cosmology and the equivalence principle

    hep-ph 2025-07 conditional novelty 6.0 of 10

    In dark bubble cosmology, non-abelian gauge fields like gluons would couple to induced gravity with the wrong sign, making the proton's gravitational mass about 1% of its inertial mass and ruling out the scenario agai...
