Wow. No way! Of all the numbers about the cosmos we hear over and over, we never hear the real size of the universe... probably because no one's willing to try to explain the details behind it.

Thanks!

@ kflann:

This is a sort of counter-intuitive thing. A sort of commonsense logic says that if the universe is 13.7 Billion years old, we should only see 13.7 Billion light years into it in any direction.

But see:

I was very surprised when I found out about this.

Thanks for the comment.

Isn't the radius of the observable universe 13.7 billion light years?

Sometimes, I run out of decent wrong answers. But why just leave it blank? There are some answers I just know that nobody will select...

Great quiz.

I had a laugh when one of the possible answers for what the local galaxies belonged to was the American Automobile Association.
