is it possible to......

[ducatilover]

so if an opposite particle meets another then it will cause a reaction, eg bounce off?

[MisterD]

thats excatly what my brother told me. i'm really interested in anti-matter though, how is it umm created?

I think it's one of those things they do with the nuclear accelerators where they whiz particles into each other at a significant fraction of light speed and look at what the resulting nuclear train-wreck creates.

Me, I like Quarks, anything who's properties are strangeness, colour and charm just has to be cool

[enigma51]

reactions are caused when you play around with the protons etc not when you simple move to towards each other (they will bounce in that case which is a reaction but not what i think you are thinking about) remember particles is like stones (actualy stones are a bunch of particals) and the rule says that evey action has reaction physics 1 0 1 so if two particals meet it will have a "reaction" but it will depend on how they meet to what the out come is.

Nuclear reaction is when you split the the protons and the protons will automatically try and balance it out protons = + electrons = - that is was causes the energy.

Now fusion is the the exact opposit its when you combine the thingy's together to create something new!

The whole interest in antimatter is that when it meets matter the two annihilate each other and produce lots of energy. Antimatter is reckoned to be created and destroyed all the time inside stars.

But dont take my word for it I slept through most of my physics classes!

I feel like I'm going to turn into the Hitcher of Physics here.

Nuclear fission and fusion are both nuclear reactions. Fission being the splitting of a large nucleus (cluster of neutrons and protons) into (usually) a smaller nucleus with the emission of radiation (alpha / beta / gamma)

Fusion is going the other way, and, as in the sun converting hydrogen into helium and then progressively heavier elements. So, getting all space-cadet on you every single atom in your body was once inside a star.

hmmm interesting is that how we get big arsed chunks of rock floating around?
so then how is anti-matter formed or created?:spudwhat:

[Indiana_Jones]

i was just wondering, is it possible to bring an object or just a single atomic particle to absolute zero? [-273.149c if my 5th form memory serves me right] and if so wont the object or atomic particle be completely stationary? or motionless? [i got bored on the trip to wellington to see the surgeon yesterday] so if anyone here could explain it to me....

and i really want to learn about anti-matter, i'm assuming the only way to store anti-matter would be in an electro-magnetic feild...otherwise it will be in contact with matter and umm yeah we would cease to exist depending on the amount of anti matter ofcourse

It's not difficult to construct an Infinite Improbability Drive. To quote Adams, "The principle of generating small amounts of finite improbability by simply hooking the logic circuits of a Bambleweeny 57 Sub-Meson Brain to an atomic vector plotter suspended in a strong Brownian Motion producer (say a nice hot cup of tea)" has long been known. The actual procedure was discovered by a lab student reasoning as follows while he was sweeping up the lab at night:

"If, he thought to himself, such a machine is a virtual impossibility, then it must logically be a finite improbability. So all I have to do in order to make one is to work out exactly how improbable it is, feed that figure into the finite improbability generator, give it a fresh cup of really hot tea . . ." and *poof* the infinite improbability drive was constructed out of thin air...

Albert Einstein: And what is it you want to patent, Herr Smith?
Mr. Smith: I call it "Smith's Theory of Relativity."
Albert Einstein: Hey, look at this. *pointing at the paper*
Mr. Smith: What?
*Einstein bashes Smith's head with the sliding door, takes the paper's and flees*

To quote Pratchett, "Physicists have calculated that the odds of such a thing existing are a million to one against, but Wizards have calculated that million to one chances crop up nine times out of ten."

(or something close to that anyway)

The cool thing about quantum physics is that it postulates that entire universes can just pop into existence from nowhere. Or , strictly, if I remember correctly, out of 6 (or 20 ?) dimensional space. The REALLY cool thing is that, the former being so, by corollary, existing universes (like ours) can pop OUT of existence just like *that*. I find this a very reassuring concept.
