The new 'dropping the A-Bomb'

In the future, people imagine everything from starships and robots to super powerful medicine will exist. One of the key points to this is antimatter, which makes up both sci-fi weaponry and even powers Star Trek's USS Enterprise. The question is: is potentially destroying the Earth really worth a few little science experiments? Swiss physicists reported after dropping a portion of antimatter that "The world didn't blow up, but there were some tiny explosions." One previous theory regarding antimatter was that if matter came into contact with it, in the process of cancellation, a black hole would periodically form. In other words, the world would blow up. This breakthrough in science may be the key to our future. Luckily, these scientists weren't testing antimatter to see if it created a black hole, but rather testing gravity. They had an assumption that due to the fact that matter will be pulled(by gravity) to a larger chunk of matter in a vacuum, and since antimatter is, well, the opposite of matter, the "ball of antimatter [would then] fall up."

I know that the moment I understood exactly what was being tested, my mind was racing. I automatically decided that if indeed antimatter 'fell up' we could easily have a new form of propulsion in our sights. In explanation, we could, in the case of antimatter falling upwards, tether a chunk of antimatter to an engine, and bombard it with matter in the direction we wish to go. 

What are the possibilities of this 'new' quantum physical concept? It's very prospective, though testing on earth or near it could be very dangerous. These Switzerland scientists were hoping to use gathered information to better understand "how the universe developed after the Big Bang." So are we going to leave it to a bunch of atheists to potentially destroy the world? Is understanding something that won't help us directly really worth this much of a risk? Even though these scientists with all their skill have been experimenting in an entirely safe and cautionary way, what happens if there's an accident? In their published report, they mentioned "tiny explosions." These explosions were the product of just a few anti-hydrogen particles, imagine what happens if they decide to make heavier elements and drop them. Bigger explosions, maybe even some new anomalies. The point is, Chernobyl was an accident, next, CERN, there laboratory might just 'dissapear.'
