![]() Today, however, there is no evidence of antimatter galaxies or clouds, and antimatter is seen rarely and for only short periods, for example, during some types of radioactive decay before it annihilates in a collision with normal matter. In that way, it could help to answer a question that has long plagued physicists: Why is there only ordinary matter in our universe? Scientists think antimatter and matter should have been produced in equal amounts during the Big Bang that created the universe 13.6 billion years ago. ![]() Those experiments would give researchers more information on the antimatter's properties. ![]() (To date, since the beginning of the project, Fajans and his colleagues have trapped 309 antihydrogen atoms in various traps.)Īnd the researchers plan to improve on that, with the "hope that by 2012 we will have a new trap with laser access to allow spectroscopic experiments on the antiatoms," Fajans said in a statement. The team has now managed to capture 112 antiatoms in this new trap for times ranging from one-fifth of a second to 1,000 seconds, or 16 minutes and 40 seconds. ![]()
