Matter and Antimatter testing?
98727
Dan Brown always starts his trash novels with a "disclaimer" that all things within the book are true.  Unfortunately, he misleads a lot of readers with this fake claim.  The part dealing with matter and antimatter is that antimatter is strictly theorectical.  The reason antimatter was theorized was to explain why the observable universe is chaotic and why there is too much measurable energy to equate the creation of planets.  The ever changing antimatter/matter chaos tries to explain this.\n\nThere is real use of magnetic fields to capture sub atomic particles though, but these would still be considered matter becuase they do indeed have atomic weight.  Don't worry too much about it.  The technology to create an antimatter "bomb" will kill many more scientists developing this psuedo science than an actual terrosrist utilizing this drummed up fictional bomb.

The opposite of matter.

Antigravity, but that hasn't been proven.  Magnetism works when you have two magneticaly charged objects.

Anti matter is negative version of matter.To differentiate the matter and antimatter we consider the atomic levels of matter.Our own matter is made with atom of centraly proton of positive charge & charge less neutron called nucleus.And a negative charged electrons revolving around it.But in antimatter nucleus is  negative charged proton(anti proton)& electron of positive charge (anti electron) revolving around it.\nI think that matter and antimatter repell each other,have a negative gravitation.

If Anti- Gravity means repulsions between two gravitational masses;then the answer to this excellent question exists.\nFirst if we look how gravity affects atomic elementary particle we could understand anti-gravity.\nThere is a point lets say where the gravity field between the electron and proton intersects in such a way that a repulsion occurs.This shows that no two particle can actually come togheter and stick to each other.So particle integrity is maintained.The phenomena of anti gravity is real.This is in full agreement with experiments in qunatum mechanics, which have shown repulsion between particles.

One is the simple physics of collisions. Rutherford Back Scattering is used today to measure thin films. It is just bouncing balls so is not affected by chemistry.\nThe physics of elastic collisions was well defined by others. (billiard balls with balls of different masses) People used radioactive sources and understood the nature of alpha particles. So when the very thin film of gold didn't stop most of the particles, there was no surprise. The ones that did, were the surprise and the interesting/useful part of the experiment.\nNewtonian physics, elastic collisions, alpha particles, radioactive sources were available.\nThis should be a start.

the simplistic answer involves the electrons, protons and neutrons. the more complex answer contains up quarks, down quarks- which are the building blocks of protons and neutrons. \nThen if we think about it we have also got anti-matter, which is involved in bonding and so forth, and so must be around somewhere. positrons, anti-bonding orbitals, etc.

Particle detector generally for high-energy experiments I guess..

antimatter cant rely be used for anything,it is just a scientific oddity that is studied by smarter people.the two property's of antimatter i know of is that it has negative gravity(but it cant be used to mack things levitate)and that it will explode with a extrema force in some conditions.so the only possibly practical use would be bomb making but we don't have the necessary tech.

Question:  If matter cannot be created or destroyed,  \nwhere did the first(present)matter come from?\n------------------------------------------------\nThough, it is still a big question, if the "Big Bang" was\nreasonably symmetric the universe should have started out\nas pure energy, or as equal parts antimatter and matter\n(matter can be destroyed and turned into pure energy by\ncombining it with antimatter, and energy in some other\nform can be converted into equal parts of matter and antimatter).\nThe big question is, why do we normally only see matter around\nus, and not equal parts of both matter and antimatter? (Of\ncourse it would be pretty hazardous living around stuff that\ncould annihilate you!).  There are a bunch of theories, but as\nfar as I know, nobody really knows yet.

i used to work at a particle physics research lab.  our everyday operation was to take matter and antimatter and smash them together at extremely high energies; to do this required storing some antimatter.  \n\nwe did this using a specialized type of particle accelerator called a "storage ring" which is essentially a big circular tube, under vacuum, with a bunch of magnets to guide the positrons (the antimatter counterpart to electrons) around the circular ring.  as they went around at the speed of light, they'd lose some energy so we'd have to re-accelerate them at every turn.  but that's essentially it.  here's some pages to learn more about storage rings:\n\nhttp://www.lns.cornell.edu/public/lab-info/ring.html\nhttp://www2.slac.stanford.edu/vvc/experiments/bfactory.html\n\nat any given time we stored about 10^13 positrons, which is actually a considerable amount.\n\nif you don't need to keep them at high energy, you can use a form of magnetic confinement, which basically works on the same principle as the storage ring.  often this is called a "magnetic bottle" or by its real name, the "penning trap":\n\nhttp://www.physik.uni-mainz.de/werth/g_fak/penning.htm\nhttp://www.aip.org/png/html/penning.htm\n\ncheers!

Read Angels and Demons. Although the antimatter making technique is totally impractical, it just might be possible to store the stuff in a hand-grenade sized container. Magnetic suspension has already been done, although it would make a large hand grenade with current technology.\nhttp://www.levitron.com/\n\nA truly perfect vacuum really is impossible, but a near-perfect vacuum could be done. Just as long as you eliminate all the gas molecules floating around, you should be safe enough. http://www.physlink.com/Education/AskExperts/ae290.cfm

According to some recent research in the field of astrophysics, antimatter are particles that have the opposite charge of the particle that it corresponds to. For example, the antimatter of protons are anti-electrons (some refer to it as prolectrons) while for electrons are protrons. Theoretically, this types of particles no matter how illogical it sounds NEED to exists in nature for the sole reason of maintaining the law of conservation of mass. The way antimatter preserves this very essential law because constantly --- according to Quantum physics --- new particles pop out everywhere. Because this phenomenon defies the law of mass conservation and HAVE to exists in nature for it to work properly, antimatter need to fill in the gap. When new particles constantly pop out and disappear (the life of a particles can extends from a billionth of a second to infinity), antiparticles "bond" with them to neutralizes tha charge. For example, let's say a particle that has a positive charge appears out of nowhere in space, the antiparticle (which is a negatively type charge of the positively charge particle) "bonds" with the positively charge particles for their charge to become zero (1 + -1 = 0).\n     The darkness in the sky are nothing but void. It is just a space where nothing exists except particles poping out of nowhere. Also, it is a common misconception that the darkness in space are called dark matter because of what the name implies. However, dark matter in plain astrophysics definition (shortened) are matter that had been the product of the "creation" of the world and all of its after affect. For now, theses matter cannot be seen by our eyes nor any telescope out there, but it can be seen through complex geometry and calculus.\n     Light is considered to be a particle that has both the characteristic of a wave and particle. We call these characteristic as wave particle. \n     Also, as a side note, it's true that time doesn't exists in reality, but it DOES exists in its own different dimension. If you want to know why, post a question.

Corresponding to each kind of particle, there is an associated antiparticle with the same mass and spin. Some particles, such as the photon, are identical to their antiparticle; such particles must have no electric charge, but not all charge-neutral particles are of this kind. The laws of nature were thought to be symmetric between particles and antiparticles until CP violation experiments found that time-reversal symmetry is violated in nature. The observed excess of baryons over anti-baryons in the universe is one of the primary unsolved problems in cosmology.

The bible could be the place where he got his theory, but unlikely.  The theory that anti-matter exists comes from the big bang theory, which is comes out of scientific thought that there could be another explanation to our existence.  The liklihood that someone would come up with a different explanation using someone elses is small.  And anti-matter is a pretty far-fetched theory with no observable, reproducible, reproductions of anti-matter.

In scientific explanation\nThe basic particle of a matter is atom. Its also divisible but then the properties of that matter will not remain.\n\nThere can also be said every matter is from electron, protons and charge less neutrons. But then it will be devised into light.\n\nIf you look in the vacuum(absence of anything), it should be neither atom nor protons nor something...it should be "ZERO"(which is used to prove a decision "False" or absence of anything).\n\nSay "you have no answer".\nThat means you have zero answer.Think of it, keep trying and make another theory. :-D

This conversion is done daily at particle accelerators. The problem is that it is exceedingly difficult to produce much matter this way since anti-matter is always produced at the same time and because the energies needed are huge. So you will never seea hunk of matter that was produced this way, you can see the tracks of the particles that have been.
