anti-matter and a frozen atom
lets see here lets go on this topic. what do you think will happen when/if we get an atom to completely stop. end of the world? nothing? just have a really really cold atom? and also i was watching history channel they were talking about futuristic weapons along with weapons and devices we would find on an alien spacecraft. talking about how flying saucers would be ideal travel but how to controll one and crap. anyway they were mentioning how this spacecraft they imagined up would use antimatter as fuel, and that we have a facility making anti matter even though its will take like a trillion years to get a penny's worth. they said anti matter is the exact opposite of matter and if it comes in contact with matter it creates a huge explosion. anyway antimatter is where the neuclus of an atom is proton and election and the protons are circling the atoms. they used some example of how much power a penny of antimatter could do, but i forgot the example. i dont know why i mentiond this but what are your thoughts.
Do you mean freeze like stop from going from place a to b or like the electrons stop circling the nucleus or both? Anyways it's a cool idea. I never thought of it before. I can't really imagine or don't know enough to imagine what it would be like...I'm guessing it would explode from having so much energy trapped up. Is it even possible? I don't know. I'm too tired to think right now.

But surely, to stop an atom, you'd remove all energy from it, so an explosion wouldn't be possible?
At least, that's how my understanding of physics and chemistry tells it.
But then, the energy needed to stop the atom from collapsing in on it's self... that's another story.
Hmmm. To be honest, I don't think I've the level of understanding to come up with any great theorys on this.

I read something about this somewhere. When the temperature reaches what is called absolute zero, which is 0K, -273°C, or -459°F, all atoms stop moving. And since everything is made of atoms and atoms are always moving, the world would cease to exist as we know if absolute zero was achieved.

Firstly on the terperature point: you can't remove all the energy from an atom due to the mass-energy equivalence(if you did there would be problems with the conservation of energy principle, that would be cool if you could though
), however, you can remove a lot of the thermal energy from an atom, though there is dispute whether absolute zero temperatures are possible in matter. Anyway, from therotecial physics it would be highly unliklely (read impossible) for an absolute zero temperature to open a wormhole or explode by itself. Basically what I'm getting at is that if you were to get at atom to absolute zero it would just be a really cold atom (apart from soem weird stuff that happens, mabye I'll come back to it another day
)
On the anti matter point: Antimatter is essentially the same as matter except that it has a different quantum spin, ie. the subatomic particle (in an abstract sense
its really confusing, even if you are studying it) spins about its axis in a different manner(direction). In the event of matter meeting antimatter it gets anhilated producing huge amounts of energy due to the mass-energy equivalence E=mc^2 whereby the mass of the matter and antimatter is converted into energy. If antimatter could be stored effectively (which is difficult as it would interact and annhilate any matter based cointanier) it would be a very good fuel source. Perhaps see the wiki page: http://en.wikipedia.org/wiki/Antimatter for some more info/links, I've rambled on enough already.

FROZEN ATOM
Frozen atom = zero Kelvin degrees = no movement = absolute zero point
That can't be measured or found anywhere.
The only place where is 0 Kelvin by former understanding is the in the borders of our expanding unverse. But where is matter or light or whatever excistance, there can't be absolute zero.
A single photon would break the zero. That way it can't be even measured because you can't sense absolute zero with any instruments.
DARK MATTER
Who knows... Perhaps something completely useless, but it can on the other hand be the matter that leads to the destruction of the universe, but turning the expansion to shrinking. Who knows...

So a frozen atom is kinda like a paradox. Matter can't be freezed to absolute zero without breaking the excistense. But then what is absolute zero? Does it excists? Gets too complicated...

"Pair Production" is a process where a high-energy photon (light/EM wave) becomes an electron and a positron. (A positron is the electron's antimatter). "Pair Annihilation" is the reverse process, where an electron and positron collide and become two photons.
This is physically possible as long as energy and momentum are conserved. That is, the total energy of the electron/positron pair must be the same as the photon(s) produced, and those photons must have the same momentum as the original particles did just before collision.Here is a page that goes over the math necessary to understand how this happens.
So when matter and antimatter meet, it doesn't make the world explode or cause a wormhole in the universe or anything crazy like that. It just means that a high-frequency photon (light) is produced, which still has a tiny amount of energy on a human scale of things. But I guess if lots and lots of pair annihilations took place at once, it could cause some damage.
A particle with no movement is a physical impossibility. It cannot exist in reality. This is because of Heisenberg's Uncertainty Principle, which states that the uncertainty of a particle's position times the uncertainty of the particle's momentum can never be smaller than a certain value. That is, dx*dp > h/(4pi) where dx and dp are the uncertainties I mentioned, and h is Planck's constant (h=6.6*10^-34 Joule-seconds).
So if a particle had no movement, then dp=0 and this principle is violated. However, h/(4pi) is an extremely small value and scientists have come very very very close to getting atoms to slow down to almost zero speed-- check out Dr. Eric Cornell's and Dr. Weiman's recent nobel prizewinning research.
The reasoning behind all of this is from our understanding of Quantum Mechanics, where Heisenberg's Uncertainty Principle and all the other stuff I mentioned have been proven mathematically. It's long and complicated and I forget how it goes, but its derivation can be found in textbooks on QM (I mean real books on quantum theory--the kind where there are more equations than words--, NOT that hokey new-age 'metaphysical' bullshit that we've all been exposed to, such as what the bleep do we know. ugh. complete trash.)
Ok I've strayed off topic and typed way too much so now I'm done.
