Re: [vsnet-chat 1931] Re: Visually observed highest-z object?

   By using the special relativity, the recession velocity v becomes

   v = c * (2*z + z*z)/(2 + 2*z + z*z)

   At z = 3.41, v/c = 0.902.  By assuming the age of the universe 15 billion
years, the distance becomes 13.5 billion light years.

   This formula is, as far as I know, most popularly used in converting
z to the conventional distance.  [Arguments very welcome ;-)]
