]]>In anticipation of future experiments, the authors investigate in a model independent manner, whether scalar fluctuations induced by inflation correlate with the tensor fluctuations that are also produced. They do uncover a correlation but find that the amplitudes of the tensor modes are considerably lower than those of the scalar modes, thereby rendering the tensor modes de facto scale invariant for all observational purposes.
