  The "Comment on: Detecting Vanishing Dimensions Via Primordial Gravitational
Wave Astronomy" [arXiv:1104.1223] is misleading and premised on a
misinterpretation of the main content of Phys. Rev. Lett. 106, 101101 (2011)
[arXiv:1102.3434]. The main claim in the comment - that in some exotic theories
different from general relativity (GR) there might be local degrees of freedom
even in lower dimensional spaces - is trivial. Nevertheless, the authors of the
Comment fail to come-up with a single self-consistent example. This claim,
however, has no implications for our paper, in which we make it clear we are
working within the framework of "vanishing" or "evolving" dimensions as defined
in arXiv:1003.5914.
