"We show that if the long-wavelength perturbations evolve with time,  a
local observer would infer that our universe is not expanding as a
homogeneous and isotropic FRW matterdominated universe with Hubble rate
H = (2/3)^t−1, where t is cosmic time. On the contrary, the
universe would appear to have an expansion history that depends on the
time evolution of the super-Hubble perturbations. Potentially, this
could lead to an accelerated expansion."

This also satisfies the conditions in the Cravens study which posits a
5-d space and makes BB effect real.
