OK here is one for you math whiz types.
Assuming the most distant object visible in the Hubble ultra deep field image is 13 billion light years old (I don't know that number to be correct so if you have a more accurate one please feel free to substitute); How far from Earth was it when the light captured by Hubble was emitted? How far from Earth was it when the light captured by Hubble was detected?
