This is crazy, I Was Just reading about this today in Max Tegmark's New Book: ‘Our Mathematical Universe’ and was thinking all day about how we could detect these Inflation ripples. I imagined if they did exist they would appear like Tree Rings, except theses would be Inflation Tree Ring. I don't know yet if they appear this way, but I'm glad I don't have to wait around for the answer. I thought this was going to be like the Higgs Boson all over again.
