Anti-matter

has any one heard of this being invented ive heard rumours but lack any proof and im curious to find out if any one else has hear rumour has it that anti matter can be used as a fuel and also as a weapon

Antimatter is not really something that can be invented... It exists... very VERY rare... or does it exist?

In 1930, the theoretical physicist Paul Dirac predicted that for every particle of matter, there exists an equivalent particle of antimatter. The existence of antimatter was confirmed in 1933 with the discovery of the positron, the antimatter pair of the electron. The theory does not mean to say that every proton in the universe must have a ghostly antiproton pair; rather it simply means that matter in the universe can be made of "real" matter, like protons and electrons, or it can be made of antimatter, like antiprotons and positrons. Theoretically, there should be no difference between the two possibilities. Each antiparticle has the exact same physical and chemical properties as the equivalent antiparticle with one exception: they carry the exact opposite charge.

this www.cern.ch company is said to found/invented it but im not sure if they have i aint found it on there site

wat u think?

First of all take a grammar lesson. Second of all, did you notice I said it was too hard for you too understand!

Already a better thread! Mine!

y dont u take a lession on how not to be a asshole

Short cuts like 'y' used for the word why and 'u' used for you does make it difficult to understand what is going on, and the grammar and spelling does need work. Even too much punctuation is better then none. At least with that we can kind of figure out where your thoughts start and stop.

Click the link in that quote and READ. It really isn't that hard to understand. There is a difference between invented, created, and found and if you can grasp that idea, you will not have all to much trouble understanding what [anti]matter acctually is.

i think it exists, many things do. its just curiousity and counsciousness that creates the blank spots. the spurring of questions in knowledge.

alot of it makes perfect sense if you ask me. i mean atoms are here, right?

what i dont really get is WHY matter and anti matter destroy each other on contact and give of g rays, because they are identical except for charge. I mean a proton and a electron dont destroy each other do they..

A male and a female don't destroy each other either, you're comparing apples to oranges.

For every bit of matter there exists equal but opposite antimatter, so that the universes mass is effectively zero and when you combine the two you get the energy from whence its creation used.

How about they continuously destroy and repair each other?

For some reason I don't think that there is an equal amount of matter and antimatter in our universe, Natural antimatter has been found but in such a minimal amount that its hard to fathom that there is an equal amount somewhere. Its been shown to destroy each other, if there was an equal amount there would have to be a point where matter and antimatter meet and thus create a line of this mass explosions. Just maybe there is an alternate or better word a mirror universe to our own and any natural occurring antimatter is a spot where the two universes are converging. Then it is not so much that our universe average mass is 0 but the combined of the two would equal 0. This is simply an idea that popped in my head just now.

I'm not an expert, but I do have an interest in this sort of thing.

I recall, in a few things that I read, is that immediately after the Big-Bang
It is theorized that there was an equal, or nearly equal amount of Matter and anti-matter. Created as this micro-universe began to cool.

Annhilating each other in a "war" that would eventually determine the complexion of the Universe in a far-off future (now).

But Why did matter win the war? Was there more?

What if anti-matter had won? Will a positron link up with an anti-proton?
Can there be anti-helium?
Am I asking too many questions?
Does it matter?

And who, exactly, has the power to analyze all matter in the universe and determine whether it is matter or antimatter?

I'm just repeating the going theory, and to my knowledge we have no way to tell what is and isn't antimatter unless it is colliding and exploding. That doesn't mean there aren't entire galaxies of antimatter that we already know about but haven't realized as antimatter.

Actually there was more matter than anti-matter (well, for someone else it might be other way) after big-bang.
Otherwise there wouldn't be any matter in universe.

There's nothing preventing that... until anti-matter hits to normal matter leading to annihilation of both.
(so those anti-atoms would have to be in complete vacuum)

Used as a fuel? That would be wonderful if you could produce and contain it efficiently.

Used in a weapon? That is something that would be unthinkable even if we could produce it in large quantities.

I've read that one trillionth of a gram is enough to vaporize a human being. Given that, one gram could annihilate the entire human race one hundred times over!

Presently, it's created in particle accelerators by focusing protons, traveling at a near-speed-of-light onto a target of nickel foil. The high speed collisions then produces new particles and anti-particles happen to be a by-product of these collisions.

Almost always, the anti-particles are destroyed when coming in contact with ordinary matter, making it difficult to collect. Very little is collected worldwide for research.

Here's a couple of links that may give you more information:

science.nasa.gov...

Good luck with your research.

That must mean amount of energy released in annihilation of that amount of anti-matter is enough to vaporize human. (in annihilation anti-matter destroyes equal amount of matter, so annihilation couldn't do that)

And in weapons anti-matter would really give best "bang for pound" because in fusion only ~one percent of matter is converted to energy but in anti-matter bombs it would be 200%. (because annihilation destroys also equal amount of normal matter)

And just that one amount of stuff would be mathematically enough to kill whole population doesn't mean it would be that way in reality.
Strongest poison (even stronger than VX or any chemical weapons/poison) is neutoroxin produced by Clostridium botulinium bacterias, spoonfull of it would be enough to kill whole population of US but do you think it could be "distributed" so effectively?

BTW, isn't it ironical that nature still wins human when it comes to most efficient way of killing?

So anti-matter has been proven to exist -- it's not just a theory?

How is anti-matter defined? Is it a nucleus of electrons & neutrons with orbiting protons, or do the electrons and protons in a "normal" atom simply switch charges?

The 2nd post in here is from UM_Gazz and has a quote in it, click on the link inside the post and read it all. You should be able to understand what (anti)matter actually is.

That's what some books say about the energy release of matter/ani-matter annihilation.

It also mentions that the mass of some anti-matter the size of an ordinary raisin, would be about the same as all the energy released from a Space Shuttle flight, from the liquid fuel and solid fuel combined.

I forget the books author, because I checked it out at the library here in town. There are several books on the subject. You probably could go to Barnes and Nobles or Books-A-Million and buy one.

P.S. When anti-matter and matter are combined, both parts ARE "detroyed" with a release of a tremendous amount of energy when you compare the amount of material involved.

When things cool down though, the "energy" coalesces back into new matter. Pretty wild isn't it?
