Is an absolute zero temperature possible?
TheCrypteral
So this was a question I've had for a while, but is absolute zero possible with nothing?
By the way, absolute zero is simply a temperature with literally zero heat energy
There are a few reasons why scientists think it's impossible, because all things have energy, and the default type of energy that every other kind of energy (electrical, kinetic, etc.) transfers to is heat energy which means everything has to have at least some heat in it.
But if everything has heat, what if we tried nothing? No matter, no energy, absolute nothingness. Would that technically be absolute zero?

umm i think youre doing too much thinking. i dont have enough braincells for that.

I thought I hid this cause I was tired of explaining physics to people how did you find it XD
1
No.

Is it possible? In theory, yes. In this universe? No.

Im not a physicist so im no where near qualified to answer this but i think that it is possible its just that that's not what it would be like. i think it would be like changing the way something spins, where the point where there is 0 motion would be so quick that you would barely notice anything. another thought is the fact that it would be like balancing a pencil on its lead, you can do it, its just the conditions would have to be nanometer-picture perfect but the gas molecules around it will just move it around and topple it over so for example space or a vacuum would be absolute 0 if all the stars and stuff producing radiation were not there. TL:DR It would have to be a thing just it would only last miliseconds

Multiverse theory states that the laws of physics are the same in every universe
but im not gonna spoil the answer to that…

I don't care

then why tf would you comment
2
idk

So you did care enough to click
2
yep

And i care if theres a supermoon tomorrow because the moon just appears bigger and theres almost no other changes making the event useless to watch

As I good remember liquid Cessium or how is the element called needs 0 K to change from gas to liquid
As I good remember 0 K is -273 C, where Kelvins cannot go under minus

That's not possible

I am not a physican or a person who has huge knowledge about these types of things
Maybe on some planets that far as the time to get up from the bed, would contain a lower temperature that would beat cessium

Actually, absolute zero, or 0K is where its so cold that molecules have absolutely no energy, meaning they stop moving entirely

Interesting

Almost anything can be achieved, and this is no exception. We simply haven't yet figured out how. Remember that time Dr. Lee De Forest said man would never reach the moon? Ok, probably not, but it happened, and look where we are now

And im Bill Nye

the temperature of absolute zero can't be reached since everything in the universe vibrates. as long as there is some particle motion, absolute zero cannot be achieved

Putting it back on community feed

it is purely theoretical last time i checked

0K (0 Kelvin) is the coldest anything can get. It is exactly equal to -273.15 Celsius. It’s not possible to get colder than that
absolute zero on wikipedia
absolute zero on wikipedia
| Absolute zero cannot be achieved, although it is possible to reach temperatures close to it through the use of cryocoolers, dilution refrigerators, and nuclear adiabatic demagnetization. The use of laser cooling has produced temperatures of less than a billionth of a kelvin. At very low temperatures in the vicinity of absolute zero, matter exhibits many unusual properties, including superconductivity, superfluidity, and Bose–Einstein condensation. To study such phenomena, scientists have worked to obtain even lower temperatures. |

My first thoughts go towards dark matter since scientists agree that it does exist, yet it somehow manages to go through everything seemingly completely unaffected by anything. So it may just be a kind of matter, which will consistently stay at 0 degree's as it is unable to interact with the matter that should be able to alter it's temperature.
I am merely guessing from what I've read out of Max Tegmarks books, explaining what we really know about the universe and dark matter :')

Yeah but that doesnt work like that because what it does is hold galaxies together, which are not at absolute 0
and also, zero degrees in what unit?
and also, zero degrees in what unit?

Kelvin

And it is able to interact with regular matter, as if it didn't we would literally have no way to know it exists.
3
Well, could read a book about it is my best answer then :'D

Alright

But dark matter still has energy.
3
Exactly

It's possible in the sense that it doesn't break any rules physics lays out (AFAIK), but also impossible in the sense that it's unlikely we'll ever be able to create an environment with absolute zero temperature
2
The coldest environment ever recorded was 1 kelvin
4
Actually I think it was about 0.87 kelvin
2
Although, it still rounds up to 1, and its still SOME energy
4
Yep.

Well it is impossible to create anything with absolute zero temperature as long as it has any energy or mass, but the question kind of wasnts to ask if ya'll thing nothingness could be counted as absolute zero or if it shouldn't be counted as anything at all.
2
Well nothingness can also be an equilibrium rather than absolute zero. If we count heat death, thats where all matter in the universe reached equilibrium and the cosmic background ceases to make any sense. Everything is equally spread about the universe, and no energy is created or destroyed. The universe becomes silent and nothingness, and direction is no longer a thing. But there is still energy, since none of it was destroyed, it was just equally spread along the universe.
2
then still the vacuum energy remains, an absolute non-temperature is physically not possible, because the vacuum is also something, and where something is, there is also movement in some form. This is how the world works.
4
I mean, even gravity is made of particles that bounce off of matter and drag things towards each other while doing it.
4
Except absolute nothingness has no energy, as energy is still a physical thing, consisting of waves and particles that we can observe. Afterall, it is 'nothing'ness.
2
Well here we go again

Yeah if it were literally nothing at all it'd be possible but I think the problem with that is that it's impossible to create nothing in a universe like ours
3
But we have
There's a lab in Australia that has created a pure vacuum where polarized particles (random particles materializing into equal parts matter and antimatter then quickly colliding and destroying each other) proving the existence of nothingness.

But that doesnt mean that the vacuum itself wasnt heated up by THE LAB IT WAS IN
1
energy transfer lol

sorry caps lock
3
bUT IT REQUIRES SOMETHING FOR HEAT TRANSFER TO TAKE PLACE AND THERE WAS LITERALLY NOTHING
1
BUT THE VACUUM WAS INSIDE A LAB THAT WAS NOT AT ABSOLUTE ZERO
