Here's something I was wondering about.

I feel like if you got matter down to absolute zero, the subatomic particles would completely de-energize and simply come apart, leaving you with a pile of loose protons, neutrons, and electrons.

The question is not about that, but about this pile. Once it 'warms up', what would happen? As energy seeps back in from the surrounding world, and these things kick back to life, what would that do?

I'd hardly think they'd just stay there like that; I picture them recombining, perhaps at random, into elements. Would this release a lot of energy?

I really have no idea, help me science peeps.

Our classic "Temperature" value, if I understand correctly, is a measure of energy that an atom/molecule has in addition to its binding / innate energies.
It is (I think) how much the thing is vibrating.
Abs zero is no vibration. Still has (possible) static charge, gravity, mass, etc. Maybe still has kinetic energy of linear velocity?
Now why something that's vibrating about itself emits energy, idk.

I'm not sure what would happen, but I doubt it would release energy . . . unless it happened to configure as a radioactive element and decay.

Really high temperatures and really high pressures is also how you assemble atoms into heavier atoms.

Fun fact - superfluid helium-4 does it’s super-fluid thing before helium-3 because of Bose-Einstein condensate related shenanigans (or so claims wiki, but I like the idea that the two are related)

If I follow the whole uncertainty principle thing, and succeed in cooling down something to absolute zero, do I in fact recreate in micro the infinite improbability drive from hitchhikers guide? By knowing absolutely how fast the atom is going, it would imply that I cannot know anything about it’s position, in other words, the atom would be at all points in the universe at once.

Then again, physics is not my strong suit. I just like thinking without standard limits, and an object, however small, that is everywhere sounds cool.

The reason I am talking about the atoms coming apart is based on it being a zero energy state, versus a very low energy state. There's nothing left to hold them together, and so they come apart with no fission reaction. I could be full of crap, though.

The concept here involves taking something down to absolute zero and then immediately leaving it in a normal environment. I'm just trying to figure out what would happen to matter if it was hit by some hypothetical 'absolute zero beam'

Now that is the ultimate garbage disposal!

I don't know if this is related or not, but there's a thing called the 'quantum foam' and it's related to zero-point energy.

See, there's constantly quantum particles popping into existence in a vacuum, but a HUGE amount of the time, they pop into existence at the same time with their own antiparticle, and thus they spin about and cancel each other out. A constant froth of infinitessimally small 'bubbles' of particles and antiparticles forming and 'popping'. But occasionally these two particles DON'T contact one another again, leading to an incredibly tiny increase of energy.

.....this almost certainly has nothing to do with the question or anything related to it, but it's fascinating nonetheless, I think. :3
