As a lay reader, it sounds like they are assuming what they are trying to prove. Yes, it produces a testable prediction, but seemingly based on a mathematical assumption derived from our observed cosmic radiation background. > This lower bound follows from the requirement of χk≥χ∗≃15.9 Gpc to address the cosmic microwave background low quadrupole anomaly As a lay reader, can I assume that no scientist would publish a theory with mathematical circularity (at the heart of the prediction)? I sure can't verify it myself.
