What approximate value for the Hubble Constant is generally predicted based on Cosmic Microwave Background (CMB) data?
Answer
Approximately $67.4 ext{ km/s/Mpc}$.
Cosmologists studying the early universe remnants, specifically the patterns imprinted in the CMB radiation and assuming the $\Lambda\text{CDM}$ model, predict a lower rate of expansion, typically around $67.4 ext{ km/s/Mpc}$.
