I'd like to cast doubt on the figure given for the size of the universe. The observable universe is around 93 billion light years in diameter, but the entire universe is many orders of magnitude bigger still.

"[the paper suggests that] at present the entire universe's size is at least 10^23 times larger than the size of the observable universe" HolbenilordTalk 13:56, December 25, 2011 (UTC)
