Cosmos Quiz Quiz Information

@ 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:

http://en.wikipedia.org/wiki/Size_of_the_universe

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.
