Comics that ask "what if?"

Randall Munroe have answered some strange questions on his web site.
He writes answers by featuring math, science and comics.
One of the stupid question he got was "what happens if a pitcher throw a ball in 90% the speed of light?".
A ball smashes in to air molecules and provides X-lays shaped like a bubble.
At the end, it makes a mushroom cloud and burns cities like nuclear weapons.
Other of the questions was "how many punch cards do we need to store all data which Google stores around the world?".
No one knows the much of data so he calculated from money.
He concluded 5 to 10 exabytes by calculating how much Google spent to make up drive fails happened every minutes or two or to electricity.
After he wrote about it in his web site, couple of week later, he got a envelope from Google.
Some Google-branded punch cards were in it.
He found that it is a puzzle when he loaded these punch cards in a computer.
He struggled for deciphering them.
At last, he read the message "No comments".
