But how could you just no longer exist? Wouldn't your body mass have to go somewhere?fnevaeva
That's why it's impossible to reach absolute zero. It defies physics and the whole law that matter can be neither created or destroyed. That is precisely why it is impossible to reach absolute zero. But you said what would happen if you did and I told you what would happen, if you threw physics out the window of course.

So what I was thinking is...What would happen if all of a sudden, all the air in the world went to Absolute Zero? Would objects still be solid? or would they randomly come apart as there is no heat to cause the atoms to move which causes an object to stay in a solid state? Because even though an ice cube is very cold, there has to be molecules moving to keep it solid, which means there is some heat.

All movement would cease, everything may become solid.

Everything would cease to exist. The vibration of the cells, particularly the quarks and other particles that make up cells is what keeps that cell in existence. If they were to completely stop all motion they would cease to exist.

It all goes back to Zero.

The reason an ice cube is solid is because the atoms are moving much slower than liquids or gases. As you get closer to absolute zero, things will become solid, and in most cases they would also shrink (at least most gases).

If the air in the earth became absolute zero, it would quickly rise in temperature from residual heat (of the sun and the heat existing on the earth). It would, however, kill pretty much everything on the surface of the planet with the air condensing into a solid mass (including the air in your lungs). Also the cold would be so intense that most would die instantly since organs would not be able to function.

Likely only bottom dwelling sea creatures that are many miles under the ocean would survive under a many-mile thick sheet of ice acting as an insulator.

iirc it has something to to w/ the uncertainty principle as well. matter @ absolute zero would presumably have zero momentum would mean it's position would have to be infinite.. so i guess that would mean it's probability of being everywhere is 100%.. which obviously makes no freaking sense :P

Something cannot reach absolute zero. You can get infinitely close but you cannot reach it or else that things would cease to exist, thus breaking the laws of physics. So to technically answer the question nothing would happen because it can't happen. However it certainly wouldn't turn solid if it did happen, it would just stop existing.

Anything that reached absolute zero would instantly cease to exist, that is what physics tells us would happen. There would thus be no more air, the planet would compress, anything made out of concrete would crumble because of the lack of oxygen. Obviously all life on the planet would die almost instantly as the lack of gas would pretty much guarantee any creatures that are made primarily out of water would lose all cohesion and simply dissolve. The earth would become basically like the moon but larger.

But what would happen in that moment of everything ceasing to exist? Would our body just fly apart, compress to a small piece, would the air hurt or feel so cold that it burns?

You would feel nothing, just suddenly you would no longer exist. Just a poof and your gone. And that is if it instantly turned to absolute zero. If you had to cool you down to that point you would freeze to death long before getting there.

Thats not actually true. An experiment was done earlier this year (Jan I think) in which scientists were able to bring a gas to negative temperatures on the Kelvin scale. The result was something like the atoms in the gas exhibited the behavior one would expect in a gas with infinite energy. The subzero gas defied thermodynamics and brings the possibilty of one day maybe having beyond 100% efficient engines (ie free energy)

I don't know, this is just physics stuff I've picked up over the years, I'm sure there are some textbooks that talk about it. But I'd never recommend a text book because they are so god-awfully boring.

You've got it the other way round. It isn't the movement the increased things solid, it is the decreased movement.
