These results are only weakly dependent on the cosmological model and remain stable, with somewhat increased errors, in many commonly considered extensions. The expansion of the universe is parameterized by a dimensionless scale factor $${\displaystyle a=a(t)}$$ (with time $${\displaystyle t}$$ counted from the birth of the universe), defined relative to the present day, so $${\displaystyle a_{0}=a(t_{0})=1}$$; the usual convention in cosmology is that subscript 0 denotes present-day values, so $${\displaystyle t_{0}}$$ is the current age of the universe.

Confidence intervals are derived from the MCMC samples, and assume the input likelihoods are exactly correct, so there is no quantification for systematic errors other than via the covariance, foreground and beam error models assumed in the likelihood codes. This paper presents the cosmological legacy of Planck, which currently provides our strongest constraints on the parameters of the standard cosmological model and some of the tightest limits available on deviations from that model. We find that the Planck spectra at high multipoles (â â³ 40) are extremely well described by the standard spatially-flat six-parameter ÎCDM cosmology with a power-law spectrum of adiabatic scalar perturbations.

We find good consistency with the standard spatially-flat 6-parameter ΛCDM cosmology having a power-law spectrum of adiabatic scalar perturbations (denoted “base ΛCDM” in this paper), from polarization, temperature, and lensing, separately and in combination.

Gravitational lensing â¢ Planck 2018 results. The CMB spectra continue to prefer higher lensing amplitudes than predicted in base ΛCDM at over 2σ, which pulls some parameters that affect the lensing amplitude away from the ΛCDM model; however, this is not supported by the lensing reconstruction or (in models that also change the background geometry) BAO data.

The cosmological parameter results explore a variety of cosmological models with combinations of Planck and other data. The Planck base-ΛCDM results are in good agreement with BAO, SNe, and some galaxy lensing observations, but in slight tension with the Dark Energy Survey’s combined-probe results including galaxy clustering (which prefers lower fluctuation amplitudes or matter density parameters), and in significant, 3.6σ, tension with local measurements of the Hubble constant (which prefer a higher value).
