Has any one heard about Anti-Matter?

Question

Like the anti matter for an electron is a positron. There is possible an anti-matter for each every particle in the universe. When matter and anti-matter collide a large amount of energy is released... This is what I've heard a lon ago... The theory cannot be ignored.

Answer 1

In particle physics, antimatter extends the concept of the antiparticle to matter, wherein 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 comes to exist on Earth outside the confines of a suitably equipped physics laboratory would inevitably come into contact with the ordinary matter that Earth is made of, and be annihilated. Antiparticles and some stable antimatter (such as antihydrogen) can be made in minuscule 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.

Answer 2

Well, you have a partial understanding of this, and I will help you to fine-tune it. Yes, antimatter is real, and for each TYPE of particle there is an antimatter version of it. However, this does not mean that there is an antimatter version of every *individual* particle, in fact there is far, far less antimatter than there is of matter.

At present the people who study this stuff believe that earlier in the universe, there was lots more of both regular matter and the anti stuff, with just a very slight imbalance in favor of what we call normal matter. They annihilated each other, releasing a vast quantity of energy (the matter itself converted completely into pure energy, by Einstein's formula e=mc squared, e for energy, m for mass, and the c is the speed of light, so if you square it, you can see that's a huge number) and what was left is what we still have, all the normal atoms you see making up the world, stars, your dog, blender, and computer keyboard.

Finally, the part about the early universe and the matter/antimatter ratio is still a theory, which not been proved, but it has been repeatedly supported by the facts and never disproved. But antimatter itself is very real, we can make it and use it, and little particles of it bombard us from space every day.

Answer 3

Anti matter is simply matter that has the exact opposite charge to its "normal" counter part. The antiproton is negatively charged instead of positive. The positron (anti electron) has a positive charge. The Antineutron (like the neutron) is still neutral. There are also anti neutrinos and other more anti versions of the more exotic forms of matter. They still have mass and still behave exactly like their counterparts in all ways, except for charge. As far as Anti-Matter galaxies or other large bodies (anti suns, anti planets, etc). These should be possible and have been theorized about before but have never been observed in nature. As far as the war between antimatter and matter. There is growing evidence that the anti particles only look identical. There may be very tiny differences in the two. If the big bang produced equal amounts of both, as the theory suggests, then there must be some tiny difference in the two or we wouldn't have a universe made mostly (or entirely) of matter.

Answer 4

Yes, when antimatter meets with matter particles, the bonds holding the atoms together cancel each other out and dissolve. This event releases pure energy. Antimatter has, in fact been produced in laboratories however only in very small amounts (I'm talking about a few atoms of antimatter at a time). I heard once that just a baseball sized amount of antimatter could make a big enough explosion to split the Earth into fragments.

Answer 5

Its not a theory--if by "theory" you mean an unproven hypothesis. Anti-matter has been produced many times in particle accellerators. There is no evidence, however, that there is a corresponding quantity of anti-matter for the normal matter in the universe--in fact, although that hypothesis was advanced many years ago, subsequent scientific research has not found supporting evidence. And what we've learned aboutthe universe in recent decades tends not to support the idea.

BTW-- a "theory" as the word is used by scientists does not mean an idea tha tis not proven. That is a hypothesis. "Theory" efers to--and only to--the various ideas explaining empirical phenomenae (the observable, measurable parts of reality) which HAVE been verified by rigorous observation and experiment.

Answer 6

yes. there are 5 states of matter we know of. solids, liquids, gases, plasma and the state of matter called Bose-Einstsein condensates. in particle physics, the concept extends to where matter and anti-matter come into contact with each other, the two annihilate-- that is they both may be converted into other particles with equal energy in accordance with Einstsein's equation of E=mc^2. research for more detail under baryogenesis.

Answer 7

well there is no other question except your title so my answer is yes, i have heard of anti-matter.

you can read about it on the internet. it is also used in many books. i just read angels and demons by dan brown and antimatter is a big part of that story and most of what they say in that book about the antimatter is true.

Answer 8

Read "Angels and Demons" by Dan Brown.

Anti-matter is real and could power the world in a non polluting way.

Answer 9

Wrong, jackball. The antimatter equivalent of an electron is an anti-electron. The anti- equivalent of a proton is an anti-proton. Read up on it and then pose a question...

Answer 10

possible but antimatter hasnt been found outside of controled labratories, and if their were larg quantities of it i the universe the power fro the force of it would consume us with such extream light it would burn off our o-zone
