My roommate read some math book and told me two facts. 1) If you could fold a piece of paper 50 times, it would reach the moon and 2)We should expect the unexpected, because mathematically speaking, we are more likely to have coincidences than not. Say, for instance, you averaged out how many times you take a train, and your friend takes that same train, because you live in the same area, there is probably actually a pretty high probability that you'd be on the same train at some point.
Someone also told me there is gas around Jupiter that looks like a smiley face. This was less interesting to me, and I was disappointed in the information they shared.
