Abstract
This paper is all about ?matter? and ?antimatter.? Various aspects of the topic of antimatter are explored such as a detailed explanation of its concept, the history of its discovery and subsequent developments. The paper also includes a discussion of the relevant theories of physics that are related to the subject and help us to understand the concept of antimatter.
From the Paper
"Man has for ages called everything that exists on earth as ?matter.? As his knowledge increased over the years, scientists discovered that matter is made of tiny particles called atoms. These atoms, in turn were discovered to have a nucleus at the center, surrounded by a cloud of electrical charges called ?electrons.? Still later, it was discovered that the nuclei contain still smaller particles named protons and neutrons. Latest research shows that even the tiny protons and neutrons consist of even smaller ?fundamental particles? called quarks. Quarks are believed (so far!) to be indivisible. This knowledge about ?matter? is relatively common. What is less commonly known is the scientific discovery that all matter or particles have partners or ?mirror image? having most properties similar to their corresponding matter but with an opposite charge (and other electro-magnetic properties). For want of a better name, scientists called their new discovery ?antimatter.? "

Abstract
A explanation of what antimatter is, where it originated, what its uses are and how much energy it can produce. It looks at the benefits of this matter.
From the Paper
"Antimatter is a rare substance that at one time was abundant in our universe. Antimatter is relatively simple, consisting of the same parts that make up the elements in our planet. The only difference is: an atom of antimatter is a ?mirror image? of a regular atom. Antimatter and normal matter both have neutrons, which make up a good portion of the mass of the nucleus. Normal atoms have negatively charged electrons which encircle the nucleus, and they also help to determine the charge of the atom. In Antimatter, those ?electrons? do not exist, they are called ?antielectrons?, sometimes known as ?positrons?, and they have a positive charge. The Protons of in a normal nucleus are also different in an atom of antimatter. They are called ?Antiprotons?, and have a negative charge."
