what is anti matter??????????

Answer 1

Corresponding to each kind of particle, there is an associated antiparticle with the same mass and opposite charges.

Answer 2

Simply put, antimatter is a fundamental particle of regular matter with its electrical charge reversed. The common proton has an antimatter counterpart called the antiproton. It has the same mass but an opposite charge. The electron's counterpart is called a positron.

Antimatter particles are created in ultra high-speed collisions.

One example is when a high-energy proton in a solar flare collides with carbon. It can form a type of nitrogen that has too many protons relative to its number of neutrons. This makes its nucleus unstable, and a positron is emitted to stabilize the situation.

But positrons don't last long. When they hit an electron, they annihilate and produce energy.

"So the cycle is complete, and for this reason there is so little antimatter around at a given time.

The antimatter particles need to be kept moving at a high rate of speed. I forget where the worlds largest antimatter machine is. It is a circular shaped building with billions of particles floating though its large tubes. If any one portion of an antimatter cell hits the wall of the tube....... KABOOM.

Antimatter




Antimatter is made up of antiparticles. Whereas ordinary matter is made from atoms, which are made from nucleons, made from quarks, antimatter is made from antiatoms, made from antinucleons, made from antiquarks. Whenever an antiparticle meets a particle, the two annihilate into a burst of radiation; for this reason antiparticles almost never exist for long enough to form an antiatom. However, they still play an important role in the world of particle interactions.

Answer 3

In particle physics, antimatter is matter that is composed of the antiparticles of those that constitute normal matter. If a particle and its antiparticle come into contact with each other, the two annihilate; that is, they may both be converted into other particles with equal energy in accordance with Einstein's equation E = mc2. This gives rise to high-energy photons (gamma rays) or other particle-antiparticle pairs. The resulting particles are endowed with an amount of kinetic energy equal to the difference between the rest mass of the products of the annihilation and the rest mass of the original particle-antiparticle pair, which is often quite large.

Antimatter is not found naturally on Earth, except very briefly and in vanishingly small quantities (as the result of radioactive decay or cosmic rays). This is because antimatter which came to exist on Earth outside the confines of a suitable physics laboratory would almost instantly meet the ordinary matter that Earth is made of, and be annihilated. Antiparticles and some stable antimatter (such as antihydrogen) can be made in miniscule amounts, but not in enough quantity to do more than test a few of its theoretical properties.

There is considerable speculation both in science and science fiction as to why the observable universe is apparently almost entirely matter, whether other places are almost entirely antimatter instead, and what might be possible if antimatter could be harnessed, but at this time the apparent asymmetry of matter and antimatter in the visible universe is one of the great unsolved problems in physics. Possible processes by which it came about are explored in more detail under baryogenesis.

Answer 4

Antimatter is the direct opposite of matter.

The atoms that make up matter contain protons (with a postive charge), neutrons (with no charge) and electrons (with a negative charge). The atoms that make up antimatter have antiprotons (with a negative charge), antineutrons (with no charge) and positrons (with a postive charge). As you can see, the charges inside the atoms of matter and antimatter are opposites of each other.

When matter and antimatter meet each other, they collide and annihilate each other completely. This produces only energy and no other products, which makes it the cleanest known way of generating energy. The reason why this is not used to generate energy today is because antimatter currently takes more energy to create than we could get from the matter-antimatter reaction, and because we currently don't have any way of storing antimatter without it being annihilated by matter.

Answer 5

Protons are positively charged and electrons are negatively charged? RIght? Yes, but in antimatter, it is the reverse. As said, when they collide, they tend to mutually annilate each other in a huge release of energy. We live in a section of matter in the universe. Other galaxies may be made up antimatter. Antimatter doesn't show up in our area very often, usually in a supercollider.

Answer 6

The opposite of matter. SOmething required to propell the Enterprise.

Answer 7

The dubs guy seems to have a profound knowledge on the subject. He is well informed too I have been to that website before. I think the circle place is somewhere in Nevada.

Answer 8

dont wast your time trying to figure it out without some proper help. all anti-mater is is the absence of matter so in theroy you will never know what it really is.

Answer 9

Are you reading Dan Brown's Angel's and Demons? I hardly remember his explaination of antimatter but don't waste your time reading it, it has the most ridiculous ending.

Answer 10

The opposite of matter. When it collides with regular matter, it causes an explosion.
