Does dark energy's 4/3 scaling affect the redshift-magnitude relation in Hubble tension?

01 January 1970 1 3K Report

Hubble tension is the name given to a conflict of measurements of the Hubble constant that do not agree with each other. Using SN gives 73 km/sec per Mpsec, using CMB gives 67, all roughly.

If so how? And if it does, could it resolve the Hubble tension?

Robert Shour

A recent article contains an estimate of the Hubble constant, H_0=66.81±0.81 km/s/Mpc. The article is:
