I understand atoms stop moving, but do electrons also stop orbiting? Absolutely everything freezes?

You can't get to absolute zero, only pretty darn close. So there is always some motion. I suggest you do a google search on "Bose-Einstein Condensate". Very interesting to see what happens at near 0 degrees absolute, I think it might be like several millionths of a degree above 0, as I recall, I'll think i'll check it myself, thanks for the question!linux kid said:I understand atoms stop moving, but do electrons also stop orbiting?

I think this is my best question so far. Learning is fun!PhanthomJay said:...thanks for the question!

Bose-Einstein Condensate only occurs with a gas cooled to absolute zero.

Well, OK maybe this question is a little too ambitious since we haven't observed absolute zero. So I will settle with near 0kelvin temps. like liquid helium. What happens there?
Ki Man said:It's impossible to stop an electron's 'motion' around an atom. we can't reach absolute zero but if we did someone did it, atoms would not move at all (relative to surrounding atoms) but within the atom, functions would continue.
you can't think of an electron like a ball going in a circular orbit. it doesn't even act like matter half the time. i suggest you watch http://dadattack.castpost.com/520670.html"
linux kid said:wow, this is amazing. So my question can't fully be answered until the electron form is found I guess.

But for now I will have to assume electrons are not affected by external temperature.
ZapperZ said:Why do you think the resistance increases with increasing temperature?
ZapperZ said:In an atom, the GROUND STATE is the lowest possible energy that the atom can be in (I could has sworn I have said this already!). The electron in the ground state cannot be forced into any lower state than this.Zz.
Danger said:Love your spelling, dude.
That aside, ZZ, I have a serious question. If the electron is forced into the nucleus to merge with a proton and become a neutron, as in a neutron star, does that represent a lower energy state, or is it a higher one because it's an unnatural condition?
ZapperZ said:That's why I didn't become a "spelling major"
I didn't know any such thing. No high-school diploma, remember...ZapperZ said:You'll notice that it requires a change in "flavor" of quarks for a proton to turn into a neutron.
Hey man, this is not high school stuff, trust meDanger said:I didn't know any such thing. No high-school diploma, remember...
I'd love to hear more about that, but I don't know that I could understand it.
moe_3_moe said:hey zz u look so educated or let's say well informed ...
now about the subject that electron will not be affected by the temperature ... we are studying now semiconductors ... and u should know linux that energy level are effected by temperature ... and energy level are specified by the electrons... so in a way temperature affect the electron...try to search about fermi energy level and conduction band and valence band...u can get some formulas relationg the energy levels with the temperature ...hope i helped in a way
mgervasoni said:I have a question, and please be nice as I am a new lover of physics:
As I understand:
1: The Bose-Einstein Condensate says the passage of light / photons can slow down at very low / near absolute 0 temperatures.
2. Einstein's theory of relativity states that the speed of light in a vacuum is the constant of the universe, not space or time or space-time, as Newton assumed.
Questions 1:
What happens inside this slowing of the passage of light in relation to (space)time? If we could slow down light, say, all around us, what would be happening?Question 2:
Is reaching absolute 0 impossible, or possible but we haven't figure out how yet?
mgervasoni said:Thanks for clarifying that makes a huge difference.. but I still don't accept theories with the word quantum in the front.. maybe someday tho I'll be forced to.

Absolute Zero is the lowest possible temperature that can be reached, at which point all molecular motion stops. It is equivalent to 0 Kelvin or -273.15 degrees Celsius.
At Absolute Zero, matter reaches its minimum energy state and all molecular motion stops. This causes matter to become extremely rigid and lose its ability to conduct heat or electricity.
While scientists have been able to reach temperatures extremely close to Absolute Zero, it is impossible to reach it exactly. This is due to the Third Law of Thermodynamics, which states that it is impossible to reach a temperature of 0 Kelvin through a finite number of steps.
Absolute Zero is measured in Kelvin, which is a unit of temperature based on the Celsius scale. To convert from Celsius to Kelvin, simply add 273.15 to the Celsius temperature.
Studying Absolute Zero can help us better understand the properties of matter and how it behaves at extreme temperatures. It also has practical applications in fields such as cryogenics, where extremely low temperatures are used to preserve and store materials, and in superconductors, which require low temperatures to function efficiently.
