If everything came from the big bang, why isn't everything entangled? Won't that mess up all our calculations?

Why did the Nazis document their atrocities in such detail, filming them, etc.?

Why planets appear perfectly round	[ "A sphere is the strongest geometric shape, and really big things are being constantly squished by their own gravity. EDIT: Got downvoted by some moron. Oh well.

How is the military spending of the US ($682 billion) justified when it's 4 times more than that of the 2nd highest? ($166 billion - China). Are we really being threatened that much?	[ "In terms of coverage and force projection the US is unmatched. They feel the need to have these capabilities in order to protect american interests in foreign lands.
