anti-matter

listen to the pronunciation of anti-matter
Englisch - Englisch
(see also particle, anti-)
Positrons and antiprotons are collectively known as antiparticles, which makes up anti-matter When anti-matter collides with matter, mutual annihilation occurs
Material composed of antiparticles, which are just like ordinary protons, electrons, and neutrons except they have opposite electrical charges and magnetic moments When antimatter and matter collide, both are annihilated with the production of other elementary particles, such as photons
A hypothetical form of matter of which the atoms are composed of anti-particles, as protons, electrons, etc assumed to carry charges opposite to those associated with ordinary matter Particles having such properties have been produced in particle accelerators
Material made from antifermions We define the fermions that are common in our universe as matter and their antiparticles as antimatter In the particle theory there is no a priori distinction between matter and antimatter The asymmetry of the universe between these two classes of particles is a deep puzzle for which we are not yet completely sure of an explanation
{i} matter composed of counterparts of ordinary matter (i.e. antiprotons, positrons, antineutrons)
Matter composed of all anti-particles
antimatter
A form of matter that has a key property, such as charge, opposite to that of ordinary matter
antimatter
(a) The opposite of matter If you were to meet your antiself - not on the whole very likely as there isn't a great deal of antimatter in the universe compared with matter - you wouldn't shake hands unless you wanted to put on a really impressive fireworks display (b) However if a goblin were to meet its antiself, they would be just as likely to pop off down the nearest pub for a chat about old times Whenever a goblin is created, so is an antigoblin, to keep the balance and avoid detection This is also necessary from the point of view of manipulation Goblins deal with the ordinary matter while antigoblins deal with the antimatter Most goblins see this as a "cop-out" due to the substantial imbalance in workload, hence the antigoblins have attained the status of "arts students" amongst the goblin community
antimatter
In science, antimatter is a form of matter whose particles have characteristics and properties opposite to those of ordinary matter. a form of matter (30) (=substance which the things in the universe are made of) consisting of antiparticles. Substance composed of elementary particles having the mass and electric charge of ordinary matter (such as electrons and protons) but for which the charge and related magnetic properties are opposite in sign. The existence of antimatter was posited by the electron theory of P.A.M. Dirac. In 1932 the positron (antielectron) was detected in cosmic rays, followed by the antiproton and the antineutron detected through the use of particle accelerators. Positrons, antiprotons, and antineutrons, collectively called antiparticles, are the antiparticles of electrons, protons, and neutrons, respectively. When matter and antimatter are in close proximity, annihilation occurs within a fraction of a second, releasing large amounts of energy
antimatter
Matter that is composed of the antiparticles of those that constitute normal matter
antimatter
A type of matter which annihilates ordinary matter on contact For every particle, there is a corresponding antimatter particle For example, the antimatter counterpart of the proton is the antiproton
antimatter
{i} matter composed of counterparts of ordinary matter (Physics)
antimatter
Subatomic particles whose properties (including but not limited to charge and spin) are opposite those of normal matter When a particle of normal matter encounters its antimatter counterpart, they annihilate each other, converting completely from matter into energy If antimatter could be found or manufactured in quantity, and safely transported (in a magnetic or gravitic "bottle"), it would be the most efficient energy source possible, over 50 times more efficient than nuclear fusion
antimatter
When an antimatter particle meets with a matter particle they annihilate each other! Both particles disappear and two gamma rays are produced instead Antimatter does not get very far through matter before it reaches its matter counterpart but the gamma rays produced can travel a long way through matter An example of antimatter is the positron
antimatter
Consisting of antimatter
antimatter
A substance composed of antiparticles
antimatter
A material made from antiparticles The particles that are common in our universe are defined as matter and their antiparticles as antimatter In the particle theory there is almost no a priori distinction between matter and antimatter Their interactions are almost identical The asymmetry of the universe between these two classes of particles is a deep puzzle which is yet to be fully understood More Information: Antiparticles, BaBar Experimental Facility, Accelerator Positron Beam
antimatter
Matter composed of fundamental particles (anti-particles) which have the same mass and spin as the matter that makes up ordinary matter, but opposite values of other properties such as baryon number and strangeness The interaction of a particle with its anti-particle results in their mutual annihilation, with the release of energy Although anti-particles and anti-atoms (anti-hydrogen) can be made experimentally, there is no evidence for the existence of large amounts of antimatter in nature
antimatter
Matter consisting of particles with charges opposite that of ordinary matter In antimatter, protons have a negative charge while electrons have a positive charge
antimatter
A primitive type that provides a rudimentary CSG subtraction operation, removing one solid from another
antimatter
particle that has the opposite charge, parity, and time as its counterpart
antimatter
Matter composed of the antiparticles of normal matter
antimatter
matter consisting of elementary particles that are the antiparticles of those making up normal matter
antimatter
Matter consisting of antiparticles such as antiprotons, antielectrons (positrons), and antineutrons
antimatter
Matter identical in behavior to ordinary matter but containing the oppositely charged or neutral counterparts of ordinary matter Example: the proton carries a positive charge; the antiproton carries an equal but negative charge
antimatter
Matter which is exactly the same as normal matter, but with the opposite spin and electrical charge When matter and antimatter come into contact, both are annihilated with a tremendous release of energy Antimatter is the primary power source of Voyager's warp drive
antimatter
A general term for the collection of antiparticles
antimatter
Matter consisting of antiparticles: antiprotons (protons with negative rather than positive charge), positrons (positively charged electrons), and antineutrons
antimatter
Material made from antifermions We define the fermions that are common in our universe as matter and their antiparticles as antimatter In the particle theory there is no apriori distinction between matter and antimatter The asymmetry of the universe between these two classes of particles is a deep puzzle for which we are not yet completely sure of an explanation
antimatter
Matter that is composed of antiprotons, antielectrons (positrons), antineutrons and antineutrinos
