Here's one more reason to adore Katie Melua: After a scientist had taken issue with the inaccuracy of her line

"We are 12 billion light years from the edge, that's a guess, no one can ever say it's true, but I know that I will always be with you,"

she simply changed it to:

"We are 13.7 billion light years from the edge of the observable universe, that's a good estimate, with well defined error bars, and with the available information I predict that I will always be with you."

Very sweet.
