Does red shift expand the universe?

Answer:
Redshift does not expand the universe. Redshift is a physical quantity that is used to describe the expansion of the universe. The current time has a redshift of zero. at redshift 1, the universe was half the size it is now. At redshift 2, the universe was 1/3 the size it is now, and so on. if redshift is z, then

(size of universe at redshift z)/(current size of universe)= 1/(z+1)
