I will assume that the recent reported tension between the CMB and number count dipoles is real. Then, I will explore whether fluctuations larger than the cosmic horizon could reconcile the discrepancy. I will present the general picture, so anybody interested in the details may want to have a quick look at https://arxiv.org/abs/2207.01569 beforehand.
