Unformatted sample text from the term paper:
cosmology covers a wide array of topics that deal with the fundamental nature of the universe and its physical laws. However, while cosmology is grounded in reality, many of its
discoveries sound like science fiction. For example, cosmology encompasses the study of anti-matter. In 1928, British physicist Paul Dirac was trying to formulate a way to describe electronics
mathematically (Yulsman, 2003). Diracs approach to this problem was to utilize Einsteins concepts of special relativity with quantum mechanics. At this time, there were only two atomic particles known to
physicists, one being electrons and the other protons (Yulsman, 2003). Diracs mathematics led him to the conclusion that there was not one way to solve a specific equation, but two
possible ways. One answer described a negatively-charged particle, an ordinary electron, but the other answer showed something totally unexpected -- "a mirror-image particle of equal mass" but with a
positive charge, an "anti-electron" (Yulsman, 2003, p. 70). When Dirac published his electron equation in 1928, he described the problem with negative energies and suggested that perhaps they had a
relationship with particles that carry an electrical charge opposite that of electrons (Siegfried, 2002). Dirac was on the verge of anticipating the existence of antimatter. The principal question that
Dirac accessed is why, if negative-energy electrons did exist, would scientists be unaware of them. Like fish, who simply take a water environment for granted, Dirac reasoned that scientists could
be living in a sea of such particles and never realize it (Siegfried, 2002). All particles of matter are basically lazy, that is, they seek their lowest possible energy state
(Siegfried, 2002). However, as Austrian physicist Wolfgang Pauli has pointed out, no two electrons can occupy the same energy state (Siegfried, 2002). Applying this to the problem, Dirac realized that,
