Everything's fine. The University of Michigan just procured a tabletop-sized super laser is all. Oh, and they modded the heck out of it until it was basically an antimatter-firing gun. But it's fine.
The weapon — er, scientific apparatus — is basically a miniaturized version of the Large Hadron Collider (LHC) at CERN. However, that doesn't mean Michigan's device is any less powerful. The table-top antimatter gun has been proven to produce positrons at the same particle density of its big brother. A blast from the weapon lasts only 30 femtoseconds, but can produce quadrillions of positrons.
That pretty much means it's a Big Bang gun that you could strap onto your ATV. Researchers at the University of Michigan suggest that their boomstick could be used to mimic the jet streams funneling into black holes. Let's just hope they don't have any nefarious plans for world domination.
