The Hubble Tension and Early Dark Energy

Adam G. Riess, Marc Kamionkowski

The Hubble tension between local and early-universe expansion-rate measurements may be resolved by early dark energy that speeds up expansion before recombination while satisfying existing constraints.

Claims

C1strongest claim

Early-Universe solutions are currently favored and early dark energy provides a workable example that can be tested with future measurements while remaining consistent with the majority of the data.

C2weakest assumption

That proposed systematic errors in the measurements are not supported by the breadth of available data and that unknown errors are untestable, thereby directing attention to early-Universe modifications of LambdaCDM.
