Looking for Extra Dimensions in the Cosmic Microwave Background

We can only perceive four dimensions, but several standard model extensions suggest the existence of more. If that’s true, why can't we see them? One possible explanation is that these extra dimensions are compactified, meaning they have a finite length compared to the infinite standard four. Cosmology offers a very interesting possibility of finding evidence for the existence of these extra dimensions in the Cosmic Microwave Background (CMB). The CMB is an echo from the Big Bang era, and can give us important insight to the past of our universe and whether it could have included compactified dimensions.
