So what exactly are the hypothetical applications for anti-matter? Are there any?
Aside from blowing up the Vatican, antimatter, if it could be produced and stored in useful quantities, would be great for propulsion. There are also medical applications.
Also, I'd just like to point out that although the majority of physicists hypothesize that antimatter will fall "down", this has not yet been experimentally observed. There are theoretical arguments, yes, but these theories can still be falsified. This experiment is a direct test of these theories.
