i made a bet tonight for 50$ with my friend. for me to win i have to be right that absolute zero isn't possible to reach, is it possible? i know it has something to do with the third law of thermodynamics and i don't remember anyof it. please help me im poor
dogbert uhm .. i wish miriku would comment on what you just said .. people "know" about god he can't be "reached" people "know" about light travel it can't be "reached"
The theory goes like this: I forgot the exact temp, something like -460 degrees f. and all molecular motion should stop. This is IMPOSSIBLE as far as I know because: In a frozen s tate you'd know the position and speed of the atomic particles. This is impossible, I can't remember why or who stated that it's impossible, I just remember that it is. Plus, if something reached a state where it was truly frozen like that, at the atomic level, you'd have some serious issues with the whole energy may not be created nor destroyed bit. The temp. can exist, I think, but an object cannot exist at that temp. So I think the temp CAN exist in nature. Does that win the bet for you? *grasps at straws* I dunno, someone smarter than me want to verify?
cue miriku's theme (pop will eat itself - inject me)
absolute zero would be 0 degrees kalvin. thats easy to remember.
there is a little theorem that says the uncertainty in momentum and position is at least a certain constant. since at 0 degrees kalvin (by definition) nothing moves, therefore it must move a bit. contradiction, you cant reach absolute zero.
btw, a temperature is just the speed of molecules. you cant have a temperature without an object.
trivially lightspeed travel is totally possible, light travels at that speed ne? it's just impossible if you're still hung up on that whole 'mass' thing
"but miriku, doesnt light have mass by the duality of mass and energy"
kelvin. i have no idea what possessed me to type that
and i guess if you made a "thing" of an inherently uncertain position you could technically freeze it to absolute zero. like a quantum cloud or something. but since you cant tell where it is, then therefore it could be moving a bit and therefore not an absolute zero
the cat has nothing to do with uncertainty... sorta.
the cat is shroedingers and relates to the fact that an unmeasured quantum state is in fact superposed into all possible quantum states.
ie, if your sister was quantized, and you werent currently looking at her, she would be talking on the phone, eating a sandwich, masturbating, flying around speaking in latin, as well as all possible other things at the same time
the classic example is the cat in the box who's both present and alive until you open the box. the fact that the cat is also singing arias and juggling infinite copies of his own tail at the same time is left unspoken, but really, he is. it's sort of assumed in the story that the cat's only mode of vibration is alive/dead.
but it's not like we're trying to measure the cats velocity and position. if we did, we would find that by simple measuring it (bouncing a photon of it) we would be pushing it to the side a tiny bit causing it to have moved and therefore make us unsure about where it is. dig?
Some believe time is an extra dimension tied in to the three spatial dimensions, others believe that it is composed of "chronotons" which are particles of matter following quantam theory, and still others believe it does not exist. Here is a rundown on these three theories:
4TH DIMENSION: Time is actually a fourth dimension, interlaced with the three spatial dimensions (height, length, and distance, or the X-Y-Z axis, repsectivley). Therefore, time can be easily transversed. There are also other theories that comply with advanced quantam physics, stating that time is composed of several dimensions, however, those are pretty advanced concepts.
CHRONOTONS: Chronotons are believed to be the smallest unit of time possible, convienently packaged in the form of a ferimon, which according to quantam physics work together with bosons to make what we know as the universe.
TIME DOES NOT EXIST: This theory requires the least amount of "theoretical proof," that is, it requires no mathematical or physical explanation. Sure, time in the sense of earthly days->months->years is valid as it is in any situation, however, time in a spatial sense cannot be measured in any way, and therefore linear time (the only kind of time) is illusory. There is no past or future, all is one, and therefore attempting to measure time on a physics model is impossible.

Absolute zero would be so cool as a weapon; I mean, like Colossus said, it means all particles are moving at 0 speed; nothing can live. Zero heat. Just imagine- a warhead with some sort of liquid that reaches absolute zero upon contact with any organism...it would be possible to destroy the world very easily if absolute zero was possible. I don't think its possible.
