Princeton University Special Simons Cosmology Collaboration Seminar
The Dark Dimension
Abstract: Motivated from the Swampland program and combined with observational data, we argue that our universe enjoys one mesoscopic dimension of micron scale. We explain why the KK excitation of graviton in this extra dimension is a good candidate for the dark matter. Moreover, we show that the Swampland dS conjecture naturally leads to the resolution of the cosmological coincidence problem.
