Homework Help: Age of universe

  1. Apr 2, 2007 #1
    Hi i am confused as to how to calculate the age of the universe with redshift
    say for example

    The age of the universe now is 13.4 billion years old (and a critical universe).
    How do i find the age of the universe if it was a redshift at say 0.6??

    Do i have to find the scale factor first?
    I am not very sure, please help!!

    Generally questions like yours or Kingfishers get better service on the advanced physics forum,....
