They created the antihydrogen inside a stainless steel cylinder roughly 5 cm in diameter and 25 cm in length. They created a vacuum inside the bottle and chilled it to minus 269 C. The extreme cold slowed the newly formed antihydrogen, making it hard for it to speed away. And an extremely powerful magnet helped keep the anti-atoms in place.
The Universe is Asymmetrical
After the Big Bang some 13.7 billion years ago there were almost equal amounts of matter and antimatter. After the matter - antimatter collisions and subsequent annihilation, there was probably slightly more matter left over, that's were the universe comes from.
