Do you think we will ever reach absolute zero?

Absolute zero is the coldest temperature theoretically possible. It cannot be reached by artificial or natural means, because it is impossible to decouple a system fully from the rest of the universe.
Had a nice long letcher on it today, want to hear some sci-fi possibilities from Fakku! :3

Sounds like the 'faster than the speed of light' of temperature.
If that really is the case: Then no.
Besides, what would be the point of going that cold? I mean, beer has already reached the prime temperature... What more could we ask for!

I'm just assuming the person's an asshole, but who's the asshole who asserted this notion of an "Absolute Zero?"

Reaching absolute 0? Don't think it's possible.
A consequence of the 2nd law (as well as 3rd law) of thermodynamics is that a system cannot reach absolute 0 in a finite number of steps.
I might be mistaken though since physics isn't my major.

I don't think we will reach it.
I think we may get close, but never reach it.
Maybe an ice-age or something!

For your info - humanity has already managed to cool down something to 2,73°K. Now for your info 0°K (Kelvin) = Absolute Zero.
For those who understand German: Here you go http://www.weltderphysik.de/de/6299.php
As it is a bit confusing on which temperature was the actual lowest reached by cooling something down I took the "highest" value. the lowest value is included here http://www.weltderphysik.de/de/6305.php
Absolute Zero is, however still out of reach for quite some time imo, as it is difficult, if not nigh to impossible, to come up with a theory of how to reach it :)

We've come pretty close. 2-and-some-degrees Kelvin is awfully damn cold, but I don't imagine we will ever reach Absolute Zero since it is theoretically impossible.

What is the point of absolute zero. I really cannot by any stretch of the imagination see the use of it. Just one of those vanities of man kind I guess.

If you are curious as to why there is a limit just look it up.

Absolute zero cannot be achieved artificially, though it is possible to reach temperatures close to it through the use of cryocoolers. Laser cooling is a technique used to take temperatures to within a billionth of a degree of 0 K.

I dunno, there are certain drinks that are better off slightly cold that ice-cold.

Well, Planet Neptune is said to be at minus 400 Fahrenheit.
I would say it's doable because all we'll need to do is create a Isolation field, after that, make the space inside isolation field freaking cold. So cold that it makes beer taste like heaven. (Kidding i know XP)
Have you guys experienced when it was so cold that it actually became too hot for you and gave u a freezer burn of some kind? Its weird, it can be so cold that it is hot.
http://www.spaceref.com/news/viewpr.html?pid=23573
Also, the further you go away from any kind of heat source, the colder it will be, Kinda obvious XP
Here article of Planet Eris speaks of a degree minus 400, so in Fahrenheit it means its minus 800?
http://solar-system-astronomy.suite101.com/article.cfm/dwarf_planet_larger_than_pluto
Eris and Pluto are both cold, but Eris, being farther out, is colder at well below 400 degrees Fahrenheit. Pluto's temperature is about -370 degrees Fahrenheit.
So, from what It looks like, One might need to create multiple fields/ rooms in order to create layers of freeze in attempt to remove the heat from sun from the very center to reach absolute zero?

Just one of those vanities of man kind I guess.Well trying to answer this as best I can with my stupidity... at absolute zero all matter would cease to be. What we have is 'contaminated' for example the air around us isn't just is a combination of a shit load of other shit that is found in air. For us to reach absolute zero we could use it maybe to break down matter to a level we've never imagined and see just how things are made. I unno I'm stupid.

Nope we won't......maybe very very very close though.Well we've already reached like

In the world of quantum physics anything is therotically possible. We'll have to see...Well the problem is once you reach absolute zero matter ceases to exist, it'd just disappear. The container in which you used to reach absolute zero would disappear. Its not so much reaching absolute zero but containing and mainting it.

Harmonian, Think Absolute Zero can be contained by a Superconductivity Field?
After all, it seems like You need to use something Intangible to be able to contain something like Absolute Zero that destroys matter.
And Superconductivity from what some I read, Is also cold, might be able to keep absolute zero in one place.

Any machine that could create absolute zero would probably be destroyed by also being subject too absolute zero. Or at least that's my theory.

It's just like the speed of light....you can get as close as you want to it, but never ever truly reach it...

I believe it is difficult but its not impossible. It might happen for a split second or something then come back up a kelvin or two. Definately hard to contain as mentioned above by others since the substance that reaches zero kelvin would mean that all particals have seized all movement. If the container isn't zero kelvin as well, it would mean that the container's partical can still move. This means that these particals will be moving and with this kinetic energy, it will 'bump' the absolute zero particals and cause them to move (transfer of kinetic energy), thus causing heat therefore, goodbye absolute zero substance. (please dont quote me on this. This is just an assumption from what I remember back in high school chemistry)
Man... now that I think about it more... Absolute zero does seem impossible... argh!!! My head hurts!!! Too much confusion!!!

No Lau Man, even if the entire container wasn't aboslute zero, that doesn't mean the contents cant be. There can be a sort of "buffer" where it gradually reaches an abosolute zero, otherwise the only possible was for it to happen would be for an entire universe to be at abosolute zero at the same time so nothing will "bump" into each other.
Vaccumed off space where the temperature wasn't "lowered" but all the energy could be "sucked out of" would be the only way. It also isn't a widely accepted theory that the matter would dissapear. Only some scientist believe that.
Someday in the far off space future, man will discover natural absolute zero occuring on another planet. They will harvest the material to use as ice for beer coolers.
