What is the rate of expansion of the universe?

The most accurate measurement I know of is 71 ± 4 (km/s)/Mpc,

which was derived from data collected by the WMAP satellite. The

exact value isn't actually known currently, as far as I know. The

rate of expansion seems to be increasing. It seems as though the

further apart objects are, the greater the rate of expansion

between them. At closer distances, gravity is stronger.
