ANTIMATTER (part 5/5)

Antimatter for daily use

    Antimatter - a mirror image of matter - is an idea so revolutionary that even its discoverer initially feared its consequences. It annihilates with ordinary matter, disappearing in a puff of energy - the ultimate scientific experiment.

    This annihilation is a compelling scenario for science fiction. The first example was robots with brains having antimatter pathways.

    Transforming all its mass into pure energy, antimatter is the perfect fuel. Star Trek's faster-than-light science-fiction spaceships use antimatter power, but research projects have also investigated the use of antimatter fuel for real.

COST
    Scientists claim antimatter is the costliest material to make. In 2006, Gerald Smith estimated $250 million could produce 10 milligrams of positrons (equivalent to $25 billion per gram); and in 1999 NASA gave a figure of $62.5 trillion per gram of antihydrogen. This is because production is difficult (only a few antiprotons are produced in reactions in particle accelerators), and because there is higher demand for the other uses of particle accelerators. According to CERN, it has cost a few hundred million Swiss Francs to produce about 1 billionth of a gram (the amount used so far for particle/antiparticle collisions).

Antimatter Production
    Scientists in 1995 succeeded in producing antiatoms of hydrogen, and also antideuterium nuclei, made out of an antiproton and an antineutron, but no antiatom more complex than antideuterium has been created yet. In principle, antiatoms of any element could be built from readily available sources of antiparticles. Such antiatoms would have exactly the same properties as their normal-matter counterparts. The production of antielements in bulk quantities seems unlikely to ever become achievable, however.

History of Antimatter

In 1928 Paul Dirac developed a relativistic equation for the electron, now known as the Dirac equation. Curiously, the equation was found to have negative energy solutions in addition to the normal positive ones. This presented a problem, as electrons tend toward the lowest possible energy level; energies of negative infinity are nonsensical. As a way of getting around this, Dirac proposed that the vacuum be considered a "sea" of negative energy, the Dirac sea. Any electrons would therefore have to sit on top of the sea.

ANTIMATTER (part 1/5)

Antimatter or contra-terrene matter is matter that is composed of the antiparticles of those that constitute normal matter. If a particle and its antiparticle come in contact with each other, the two annihilate and produce a burst of energy, which results in the production of other particles and antiparticles or electromagnetic radiation. In these reactions, rest mass is not conserved, although (as in any other reaction) energy is conserved.

What is Antimatter?

    This isn't a trick question. Antimatter is exactly what you might think it is -- the opposite of normal matter, of which the majority of our universe is made. Until just recently, the presence of antimatter in our universe was considered to be only theoretical. In 1928, British physicist Paul A.M. Dirac revised Einstein's famous equation E=mc2. Dirac said that Einstein didn't consider that the "m" in the equation -- mass -- could have negative properties as well as positive. Dirac's equation (E = + or - mc2) allowed for the existence of anti-particles in our universe. Scientists have since proven that several anti-particles exist.

ULTRACONDUCTOR

ULTRACONDUCTOR™ defination: An electrical conductor, similar to present-day superconductors, having zero measurable electrical resistance in one dimension. They consist of organic polymers that exhibit electrical resistance much lower than the best metallic conductors and are considered a novel state of matter.

Ultraconductors™ are patented materials being developed for commercial applications. They are made by the sequential processing of amorphous polar dielectric elastomers. They exhibit a set of anomalous magnetic and electric properties, including: very high electrical conductivity (> 1011 S/cm -1) and current densities (> 5 x 108 A/cm2) over a wide temperature range (1.8 to 700 K). Additional properties established by experimental measurements include: the absence of measurable heat generation under high current; thermal versus electrical conductivity orders of magnitude in violation of the Wiedemann-Franz law; a jump-like transition to a resistive state at a critical current; a nearly zero Seebek coefficient over the temperature range 87 - 233 K; no measurable resistance when Ultraconductor™ films are placed between superconducting tin electrodes at cryogenic temperatures.
