LMAO! Please Register or Log in to view the hidden image! "Asymptotic" means that a quantity or a thing can get arbitraritly close to a reference but never get there. A nice way to visualize this is based on Zeno's paradox. You are 1 meter from a door. Take a step forward that's half the remaining distance. You're 0.5m away. Do it again, you're 0.25m away, then 0.125m and so on. You can take as many steps as you want and get as arbitrarily close as you want but can never actually reach the door (of course you have verryyy tiny feet...Please Register or Log in to view the hidden image!) Well, nothing can get to true absolute zero, but there are a few places where it's theorized to be just a degree or so above (inside giant molecular clouds). Scientists have gotten atoms to within 0.0001 or so degrees of absolute zero in the lab.
thanks for not laughing at me...oh wait Please Register or Log in to view the hidden image! lol so, where have they theorized?
Places like this, deep inside cold molecular clouds. They're all over the galaxy: http://www.paulruffle.com/molecularclouds.htm
? Umm... no. It's a fairly simple fact actually. It's been known since the discovery that molecules are little bits of matter, a century or so. Nope. It's a real, basic, well understood and proven thing. http://www.phy.hr/~dpaar/fizicari/kelvin.html
Nope. That's a solid fact also. Like I said, the only thing that prevents you from reaching true absolute zero is quantum uncertainty (and the funds from the NSF to push it that far. That's a joke...)
The theories behind this stuff are the atomic theory of matter and quantum mechanics. What they predict and are subsequently verified are scientific facts.
Some would say you're already there... HA! (sorry Please Register or Log in to view the hidden image!) You'd be very cold. That's really about it. Nothing else unusual. (of course you can't get to true absolute zero, remember?)
Nope. It's a degree or so above absolute zero. Not being able to reach true absolute zero isn't just a matter of not trying hard enough, it's forbidden by the laws of the universe.
Laws don't change? Laws can't be wrong? so pretend I got to absolute zero. What do you think would happen? Nothing? I'd just be super frozen?
Hmm... I suppose. But the laws we're talking about here are the most fundamental and well tested in all of science. Really. I kid you not. If you insist... Since this would violate the foundations of physics as we know it, I'd say you would collapse into a singularity of improbability and ruin the day for many well paid quantum physicists. Otherwise, yes. You'd just be super frozen.
Aren't they more like standing waves of probability of moving particles ? I fail to see how matter is held together at 0 K..
see, was that so difficult. :shrug: Please Register or Log in to view the hidden image! Thanks for answering my questions. :thankyou: I know it must have been exasperating for you.
Well, atoms are still bound to each other by valence electrons, even at absolute zero. Only the overall atomic motion is "stopped". When I say they don't move in a conventional sense, I mean they're not "orbiting" the way some think. They can't be moving in a nonuniformly accelerated way (i.e. circular orbits) because they'd radiate away their energy in a burst of photons and fall into the nucleus and there'd be nothing (electrons that are moving non uniformly radiate photons). That's all I meant.
Yust wondering but how would a particle behave if it got to -1°K. would it radiate cold in stead? Would the atomic motion be reversed, would it get antimatter like characteristics?
That's a completely meaningless question. How can an atom or molecule be moving slower than "not moving at all" which is what -1K implies? Please Register or Log in to view the hidden image!
