Batavia, Ill.- Scientists working at the Department of Energy's Fermi National Accelerator Laboratory have announced a significant advance in the understanding of the difference in the way matter and antimatter behave. Moreover, the physicists, from Fermilab's KTeV experiment, said they were "shocked" at the size of the long-sought result they reported to a standing-room-only audience at a seminar at Fermilab on February 24. Indeed, there was an audible gasp from the audience of physicists when University of Chicago graduate student Peter Shawhan gave the group's observed value for a phenomenon called "direct CP violation."
Fermilab Physicists Find New Matter-Antimatter Asymmetry
On the other hand, we often create matter from radiation, or from an electromagnetic field. Under certain circumstances (in the presence of atoms or other media), it is possible that a photon will create a matter - antimatter pair (for example, an electron-positron pair). Fermilab uses this phenomenon to detect high-energy photons. When such a photon enters the detector, it creates an electron-positron pair which is easily detectable.
Photons at Fermilab, Matter and Antimatter
The international CDF collaboration at Fermilab has made the most precise measurement to date of the extremely rapid transitions between matter and antimatter. The experiment has found that certain B mesons spontaneously turn into their own antiparticle equivalents -- anti-B mesons -- and back again at a rate of three trillion times per second. The result agrees well with the Standard Model of particle physics and confirms yet again the existence of CP violation -- the reason why there is more matter than antimatter in the universe.

I know that when anti-matter and matter come in contact with each other it creates a violent explosion. My question is how does one keep anti-matter separate from matter on this planet or anywhere in this part of the universe where everything is made up of matter? Isn't the air around us made of matter, the various gas and dust particles? How would you keep a non microscopic amount of anti-matter from exploding upon creation?

The even worse thing is that CERN is creating black holes on earth, i think both are stupid ideas
