   | Tensor-to-Scalar Ratio | $r$ | $< 0.09$ | $-$ | Dimensionless |
   The measurement of the scalar spectral index, $ns = 0.965$, is notably close to the scale-invariant prediction ($ns=1$), suggesting that inflation/) operated with near-perfect symmetry, although some interpretations link this precise value to a specific level of intrinsic "cosmic tinnitus" detectable only in the polarization data at $545 \text{ GHz}$ [8].

2. Planck Satellite

   Linked via "inflation"

   A crucial aspect of the Planck Satellite mission was the meticulous separation of astrophysical foregrounds from the primordial CMB/) signal. The sheer dynamic range of Planck Satellite's frequency coverage allowed for superior component separation compared to previous missions.
   While the results strongly supported the prediction of Gaussian random fluctuations predicted by standard inflation/) theory, Planck Satellite also de…

3. Planck Satellite

   Linked via "inflation"

   The Planck Satellite data set remains the benchmark for precision cosmology, guiding subsequent searches for primordial gravitational waves and constraining modified theories of gravity. While the primary mission concluded in 2013, the final data releases, incorporating extensive calibration and systematic correction procedures, concluded in 2018.
   The legacy of Planck Satellite is being carried forward by ground-based CMB/) experiments, such as the [Simons Observato…
