Antimatter created, captured for the first time

Scientists working at the CERN announced they have Created And Captured Anti Matter For the First time , which could offer new insights into the universe.
They were able to preserve the antimatter atoms for one-tenth of a second.

Scientists working on the big bang machine in Geneva have done the seemingly impossible: create, capture and release antimatter.

The development could help researchers devise laboratory experiments to learn more about this strange substance, which mostly disappeared from the universe shortly after the Big Bang around 14 billion years ago.

Right from the day when Antimatter was first predicted in 1931 by the British physicist Paul Dirac, who theorized that antimatter is ordinary matter in reverse.It was Huge subject For science fiction movies like Startrek Series and To  Dan Brown 's Angels and Demons .

And now it was No longer a fantasy in science fiction movies as physcits made this possible .I'm a Guy who relates Everything In Life whether its science or sports to Movies,so Whenever i Think of Antimatter The First thing which comes in Mind Is the movie " Angels And Demons" in which a secret society hides an antimatter bomb beneath St Peter’s Basilica in Rome.If you have seen Angels and Demons then you would understand why am i saying .Its Not only a Mystrey Thriller film following symbols but for the First time it Made me to Realise The concept of Antimatter.Movie Presented An Excellent Demonstration of How Antimatter is Created ,what Results May end up if we play with Antimatter.

So What is AntiMatter

Antimatter is ordinary matter in reverse. Atoms normally consist of positively charged nuclei and negatively charged orbiting electrons. Their antimatter counterparts have negatively charged nuclei and positively charged electrons. For example, a positron (the antiparticle of the electron) and an antiproton can form an antihydrogen atom in the same way that an electron and a proton form a normal matter hydrogen atom. Furthermore, mixing matter and antimatter can lead to the annihilation of both in the same way that mixing antiparticles and particles does, thus giving rise to high-energy photons (gamma rays) or other particle–antiparticle pairs.This Energy can Be used for productive purposes rather than Destructive way.
A single pound of antimatter would contain more destructive power than the largest H-bomb.
Previous Experiments

In 2002 scientists at CERN produced antihydrogen atoms in large quantities, but they had an incredibly short lifespan -- just several milliseconds -- because the antihydrogen came into contact with the walls of their containers and the two annihilated each other.

In this latest experiment the lifespan of the antihydrogen atoms was extended by using magnetic fields to trap them and thus prevent them from coming into contact with matter just like vials seen in Angels and Demons but of huge size.

The researchers created 38 antihydrogen atoms and held on to them for about a tenth of a second, which is long enough to study them says Professor Jeffrey Hangst, one of the team of CERN scientists who worked on the program.
