Quote:WASHINGTON (AP) - That old moon might not be as antique as we thought, some scientist think. They say it's possible that it isn't a day over 4.4 billion years old. But other astronomers disagree with a new study's conclusions. They think the moon is up to its typical age-defying tricks and is really pushing 4.6 billion as they have suspected all these years.
