The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The 6-parameter LCDM model continues to provide an excellent fit to the cosmic microwave background data at high and low redshift, describing the cosmological information in over a billion map pixels with just six parameters.

C2weakest assumption

That foreground emissions from the Milky Way and other astrophysical sources have been subtracted with sufficient accuracy that residual contamination does not bias the cosmological parameter fits at the reported precision.

C3one line summary

Planck 2018 provides the tightest constraints to date on the six parameters of the Lambda-CDM cosmological model from cosmic microwave background temperature and polarization data.
