What was Edwin Hubble's initial, surprisingly high estimate for the Hubble constant?
Answer
$500 ext{ km/s/Mpc}$
Due to limitations in early methods for calibrating stellar distances, Edwin Hubble's original estimate for $H_0$ was significantly higher than modern accepted values, measured at $500 ext{ km/s/Mpc}$.
