What representative value of $H_0$ is typically predicted when using early universe data like the CMB?
Answer
Around $67.4 ext{ km/s/Mpc}$.
When scientists fit the $\Lambda$CDM model to early universe data, such as the Cosmic Microwave Background radiation, the predicted value for $H_0$ today is around $67.4 ext{ km/s/Mpc}$.
