Absolute Zero

[Skyraz]

Absolute zero, does not exist. (temperature wise, degrees).
So if that is the case, anything less then zero, is frozen and not moving.
and everything above 0 is moving (since its not frozen).

then one could assume, if everything not frozen is moving, how do we know it is really there? Psychology states that our minds make patterns and predict what we see. We only process 30% of what we see each day, the rest is predicted by our brains.

Food for Thought. Yum!
PS: the popular myth 'we only use 5%-10% of our brain is actually false, we use all of it 98%-100%.

absolute zero is defined as zero on the kelvin scale of measurement.
it does exist, and is a measurable temperature.

 

[slysteeler]

It does exist, but we've only reached a few degrees above it as of the present.

I fail to see how you can make such a tangential jump?

Also, the better philosophical quandary comes from the analysis of subatomic particle. Atoms are composed of Protons, Neutrons, and Electrons. The Protons and Neutrons make up the Nucleus. The Electrons can be found on orbitals around the Nucleus. However, because the range of the orbital in proportion to the size of the Nucleus is rather large, Electrons can only be in one place at a time. Therefore, the remainder space where the orbital occupies is essentially a vacuum. If you can pick up on what this means, then you will realize that the computer in front of you is 99% nothing.

This is very obscure reasoning. For one: 0K isn't achievable through scientific means, but in the entirety of our universe, something is bound to be far enough away from a heat source to be absolute zero.

Also, scientists now predict in a trillion trillion trillion (times 5 more trillions) years, the universe will be dead with no stars and no remaining black dwarves and the vast expanse will be a never-moving pool of 0K blackness. So no, it's not impossible.

Also: disprove the myth with some sources

It's impossible to reach, but it still exists.

 

[Noam]

It exists, but reaching it is quite simply impossible. People have reached within. a millionth of a degree of absolute zero, but it is an absolute impossibility to actually achieve that value.

"Frozen" is at or below 0 degrees Celsius, or 273 degrees Kelvin.
The zero you are talking about is 0 degrees Kelvin.

Also, molecules in a "frozen" state still move, they just move less.

Sigh..

Absolute zero does exist, but we will never reach it.

This is because if it is reached, time as we know it would stop. Particles and molecules at sub-atomic levels will STOP at absolute zero, meaning there would be no movement in anything AT ALL.

Liquid helium can come very close to absolute zero, whereby it becomes a superfluid, as it cannot solidify and exhibits a frictionless FLOW, meaning there IS movement, but it cannot go to ABSOLUTE ZERO because then there will be NO MOVEMENT.

I think you should educate yourself before posting.

Can you explain how time would stop?

Can you explain how time would stop?

It is a very arguable debate, because absolute zero is an asympotic state there is no clear answer, but I do have a strong opinion about time.

At absolute Zero, there would not be any thermal energy to keep collections of matter moving. The theory of relativity says that space and time are not separable, so if movement is halted then technically time should also be halted. To measure time, something you can detect must be moving. If you cannot detect anything with evidence then there is no evidence showing that you can measure time. If you cannot measure time then what happens?

Although it can be said that zero-point energy is still present at absolute zero. There is no solid evidence either way, but this is just my opinion.

I understand now, thanks, but gosh, youre smart. Are you a science student or something?

My professors have always said that vibration would occur at absolute zero, but not any of the other thermal energy states (e.g., rotation, etc.), meaning time would still exist because energy/matter would still exist. I guess I just took his word for it that he was right, rather than stating a postulate... although, as you said, the whole picture of absolute zero is technically a postulate.
