Actually, there's a much scary/interesting possibility than what's mentioned in that article (though the chance is much smaller and they aren't even sure if these things exist).
There's a theoretical type of matter (sticky matter maybe? I'm drawing a blank on the name) that when it touches any other kind of matter it instantly converts that matter to sticky matter and that bit of sticky matter converts all other matter it touches and so on. Some scientists say that this thing could possibly make some of that matter so the universe would be blinked out in an instant according to them.
