abstract
In this paper we use $\alpha'^2$-corrections to the $D_{3}$-brane action to obtain a non-zero and positive cosmological constant in the induced cosmology living on the dark bubble. Its measured value, together with the value of the fine structure constant, correspond to a dark dimension of size $5 \times 10^{-5}$ m and a string scale at $11$ TeV. We conclude that the dark bubble model predicts deviations of Newtonian gravity and stringy excitations of known particles within reach of future experiments.

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

Dark bubble cosmology and the equivalence principle
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...
