Quantum Gravity Predicts Detectable Primordial Waves

A quadratic formulation of quantum gravity can generate the universe's early rapid expansion (inflation) without adding new ad hoc fields, and it implies a nonzero lower bound on primordial gravitational waves. Because that lower bound may be accessible to upcoming experiments, the theory is empirically testable rather than purely speculative. — If experiments detect (or rule out) the predicted minimum gravitational‑wave signal, it will materially reshape public and policy conversations about cosmology, scientific funding priorities, and the credibility of quantum‑gravity approaches.
