What is the shape of the universe?

  1. Apr 30, 2009 #1
    is the cmb radiation redshifted the same amount in ALL directions? as i understand the data, redshift is a function of distance between 2 points only(scalar quantity). is there a an angular component as well (vector quantity?)

    does the fact that there is a 'dipole' mean that the universe is expanding more along a particular axis? in other words, the universe is shaped like a weiner (would Einstein laugh?) The ends of the weiner are further apart so light coming from the ends would be redshifted more than light from any other direction.
