expanding universe_as i see it(2)

now assume that at any one point of time,there are consecutive cars at a distance of 100m.let a mc laren car "A" move at 10 km/hr wrt u,a second one "ferrari" in frnt of u,at 20km/hr and another "mc laren" at 30km/hr and so on.it will appear to you that all the cars are movin away frm u at a distance with speed proportional to their distance.similar phenomenon will also occur to the other cars in the row.similar is the case with galaxies in the universe.evry observer(may it be a hideous but intelligent alien),irrespective of the galaxy he or she is located in,will see all the galaxies movin wid speeds proggresively increasing wid their distance.so,the galaxies are not accelerating away frm us ,but xperimentally it has been found out that they are moving away with a much lesser speed of 72km/sec(according to cosmic scales)from each other.
