The debate about the value of present Hubble parameter H0 has heated up in recent years with more precise measurements of different techniques. The standard candle measurements at low redshift (e.g., supernovae) yield an H0 value of 74.0+-1.5 km/s/Mpc, while the standard ruler measurements at high redshift (e.g., cosmic microwave background) give an H0 of 67.5+-0.5 km/s/Mpc. The tension is...
