Frogon Posted April 17, 2004 Report Share Posted April 17, 2004 (look, its a no0b!)A few guys I know are talking about anit-matter, and I have no clue what it is or what it does. Can someone help me? Link to comment Share on other sites More sharing options...
Tim_Lou Posted April 17, 2004 Report Share Posted April 17, 2004 anit-matter are particles that are the same to that particles but having a opposite charge. example, electron-positronprotron-anti-protronquark-anti-quarkneutrion-anti-neutrion they have opposite charges, althought some particles do not have charge, but they still have their anti-particles. when a particle collide w/ their anti-particle, they destroy one another.such as electron-positron creates photons. this is the reason y anti-particles dont exist in our nature.some scientists say that in the other part of the universe, there will be a majority numbers of anti-matter while the normal matter dont exist.(anti-protrons bind w/ anti-neutrons and positrons and form matter, also other particles.) (just some little information.) Link to comment Share on other sites More sharing options...
Frogon Posted April 17, 2004 Author Report Share Posted April 17, 2004 So, if someone made a anti-matter bomb, it would destroy everything? Or would it just destroy the certain element its "anti" with, like a anti-matter hydrogen, would just destroy all the hydrogen it touched. (hey, im smart enought to use the edit button too!) do you guys understand what I am saying, or just have no clue? Link to comment Share on other sites More sharing options...
Tim_Lou Posted April 23, 2004 Report Share Posted April 23, 2004 anti-matter bomb is impossible to make, since it will be destroyed when they come w/ the ordinarily matters. thats the reason why we dont see anti-matter around us. Link to comment Share on other sites More sharing options...
Aki Posted April 23, 2004 Report Share Posted April 23, 2004 How come we don't have anti-matter in this part of the universe? I heard it has to do with the left-right symmetry. Link to comment Share on other sites More sharing options...
Frogon Posted April 23, 2004 Author Report Share Posted April 23, 2004 But, I ment if you put anti-matter on the ground, would it destroy the ground, or just atoms of the same type? Link to comment Share on other sites More sharing options...
Freethinker Posted April 24, 2004 Report Share Posted April 24, 2004 You are thinking on too grand of a scale. You are thinking on a scale of Newtonian or General Relativity level. The billiard ball atom model. Think of anti-mater on a partical level. At all times, the total energy in existence is equal to zero. In QM, a Quantum event generates a quantum pair. A particle and it's anti-particle. They balance out. They head in opposite directions. They would annihilate each other or other opposite particles. We are not talking about grabbing some glob of anti-matter and setting it on the ground. You need to think much, much, much smaller than that. YOu can find a number of good sites for this, CERN has one at: http://livefromcern.web.cern.ch/livefromcern/antimatter/index.html Or NASA's http://science.nasa.gov/headlines/y2000/ast29may_1m.htm Or Lawrance Berkley Lab http://particleadventure.org/particleadventure/frameless/antipreface.html Remember think small!

CD27 Posted June 13, 2004 Report Share Posted June 13, 2004 personally i don't think we have any antimatter in this dimension at al, for it would be destroyed instantly. you know what, i have a theory called "the theory of flexon energy", i will post it, i know it is full of mistakes, i just haven't gotten around to fixing them yet. fist off, it states that space is NOT juat a vast void of emptiness, it is an actual object. but, it is on the grandest of scales, we have absolutely no way of measuring it, because, well, it IS what we are measuring with. also, one of the things i need to fix with it, i read about a theory called Jellotivity, this theory is much much better than mine, and i actually accept it over mine. so i "murged" the two theories, and the only thing left of my theory is the inol theory, because i took flexon energy out, and left inol jello in. if you wish to learn more about jellotivity, please search for it, as i do not have permission to post it here, adn do not wish to take on the responsibility of explaining it. anyways, the aether is back in bussiness my friends, and with that in mind, EVERYTHING must be matter and not anti-matter in this dimensions, in anotehr dimension it may be the opposite, but in this one, it is simply matter. anti-matter can be created, but would be instantly destroyed as the aether would destroy it.

Uncle Martin Posted June 13, 2004 Report Share Posted June 13, 2004 Originally posted by: CD27"personally i don't think we have any antimatter in this dimension at al, for it would be destroyed instantly." The good people at CERN will be disappointed to hear that. They are currently producing 50 million anti-protons per minute. I suggest you research the subject, Google antimatter.

TeleMad Posted June 16, 2004 Report Share Posted June 16, 2004 CD27: "personally i don't think we have any antimatter in this dimension at al, for it would be destroyed instantly." In addition to what Uncle Martin stated, have you ever heard of PET? That's POSITRON emission tomography, used as a means of diagnostic scanning in the health industry. Ever hear of beta decay? It's one form of nuclear decay and is mentioned quite frequently in school texts on chemistry/physics. Beta decay is the one in which a neutron decays into a proton and a beta particle (high energy electron)...at least that's the way it's usually described (the events actually occur on the quark level). Usually not mentioned, but always involved, is the production of an anti-neutrino. Link to comment Share on other sites More sharing options...
TeleMad Posted June 16, 2004 Report Share Posted June 16, 2004 By the way, an anti-matter atom has been successfully created. It was an anti-hydrogen atom consisting of an anti-proton as the nucleus and a positron as the "electron cloud". Link to comment Share on other sites More sharing options...
Freethinker Posted June 17, 2004 Report Share Posted June 17, 2004 Do anti-matter atoms have an anti-mass? Link to comment Share on other sites More sharing options...
TeleMad Posted June 17, 2004 Report Share Posted June 17, 2004 No, the mass of protons and anti-protons, and of electrons and positrons, is the same: it's the opposite electric charges that make then anti particles. So the mass of an anti-atom of hydrogen would have the same mass as an ordinary atom of hydrogen. Link to comment Share on other sites More sharing options...
lindagarrette Posted June 18, 2004 Report Share Posted June 18, 2004 This leads to the question what is mass? Is it just a mathematical concept? The smallest measurable mass has to be a quark.So the question is, what do we mean by the mass of a quark and how do we measure it. The quantity we call quark mass is actually related to the m in F = ma (force = mass x acceleration). This equation tells us how an object will behave when a force is applied. The equations of particle physics include, for example, calculations of what happens to a quark when struck by a high energy photon. The parameter we call quark mass controls its acceleration when a force is applied. It is fixed to give the best match between theory and experiment both for the ratio of masses of various hadrons and for the behavior of quarks in high energy experiments. However, neither of these methods can precisely determine quark masses. Physics Today, Sept, 2003 Link to comment Share on other sites More sharing options...
Anthony Posted June 18, 2004 Report Share Posted June 18, 2004 Surely they are producing particles which they have determined to be and call antiprotons. forgetting the name they are particles with opposite charge that anialate Protons . You all say that anti particles dont exist and yet if Cern are producing them they clearly can exist unless you dont consider France to be part of our universe.
