"Where Did Helium Come From?" or "Jupiter & Saturn, Helium Hoarders"
All matter in the Universe is made up of three-quarters hydrogen and one-quarter helium (by weight), with relatively insignificant amounts of all the other elements (not including dark matter, whatever that is). This crazy abundance of hydrogen and helium has been around in nearly the same ratio from minutes after the big bang over 13 billion years ago. Wowza!
