Umm... actually the 2 billion (light) years was since the beginning of the
universe (arguably 14 billion light years ago), so it moved 12 billion light
years away in 12 billion light years, not in 2 billion years.

Hi,
This is the first time I've visited your site so I hope this question
is properly submitted. I recently watched a program about the oldest
observed object. It was estimate that the nebula was 12 billion light
years
away, meaning we were see it as it was only 2 billion years after the
beginning of the universe.
My question, assuming the big bang and relativity are correct, how
could
an object move 12 billion light years away in the 2 billion years since
the
beginning of the universe?
I find this quite puzzling and would appreciate a simple answer or a
referral to a web site or something that could explain this.
