Did you ever wonder what happens when and collide?

Maybe a better question is, why is there any matter left over? If matter and antimatter are created in equal amounts, and destroy each other, why didn't all the matter and antimatter in the universe annhilate and leave just energy right after the Big Bang?

Does this sort of unanswered question bother you? Well, it bothers scientists! As a matter of fact, that's what scientists are: people who try to answer questions and figure out how things work.

Scientists need experiments like BTeV to answer these questions. These experiments require powerful complex computing systems to work, and RTES provide the tools to build such systems from less expensive commodity computing components.

Scientists try to answer a lot of questions about the rules (or laws) that govern the universe, and about how things work. They may ask big questions like:

• What is the origin and fate of the universe?
• What is the universe made of, and how does it work?
• Is it even possible for us to know how everything works down to the smallest details?

Many of the experiments at Fermilab (including BTeV) concern themselves with the "big question" of what the universe is made of, and how it works. Our current explanation of the basic building blocks of the universe is called the Standard Model. However, it is not a perfect explanation, and so scientists at Fermilab and elsewhere continue to study it.
