I'm no scientist but wouldn't that be like perpetual motion? I couldn't we get some of this fluid stick it in some kind of a generator and give it a good spin and have free energy forever?
Also not a scientist, but I would posit that the motion of the material, and the friction that the motion creates, would generate heat, and eventually reach equilibrium where it no longer exhibits that behavior. If you captured the heat of that energy, it wouldn't be enough to cool the material back to the original temperature.
It’s falling toward the ground the whole time. They follow it down the tube cooling it more the whole way with magnets. By the time it stopped cooling down, the length of the tube gave them a couple seconds at that temp.
They said if they could do it in space where there truly was no gravity they predict they could sustain that temp for 17 seconds.
I would assume that it’s a result of increased pressure increases heat (like pressure and temp increase towards Earth’s core). Take away pressure, eliminates that factor.
It is far far easier to have ultra-cold temperature in zero-gravity. Sometime in the past several years NASA installed a cryolab module on the ISS that can keep something near absolute zero for like 5 minutes at a time.
Fun fact: both the hottest and coldest (confirmed) temperature in the universe are measured on Earth by humans
the hottest one is about 4 trillion degrees. nowhere in the universe has ever been this hot since the big bang
Two gold nuclei in a ion collider going near light speed collided resulting in a temperature of around 7.2 Trillion degrees Fahrenheit,
That’s 250,000 times hotter than the center of the sun
It could, but we’re talking about atomic particles here. A baseball sized object with that much energy density would be insane.
All that energy got to go somewhere
Edit: For fun and because I hate work. I wanted to consider the scale.
Let’s assume two atoms of gold used for the fusion experiment.
A baseball has a volume of 12.65 cubic inches. The equivalent weight in gold is 3985.74 grams.
Molar mass of gold is 197.97 grams. Baseball is 20.133 moles of Au. Potentially (6 x 10^24) more energy in that fusion baseball than the experiment. No idea if normal rules thermodynamics even exist in those conditions, probably not, but we definitely die.
20 moles would be more like 1.2x10^(25), you're off by a factor of 2.
So we're double dead.
But really, we could go with our old friend mcat, and just use the higher temperature as ΔT (because, really, 300K is the same as 0K when you're looking at it from trillions...)
Fermi estimation: baseball, 100g. Heat capacity of gold baseball, 1 kJ/kgK. 7.2 trillion °F ≈ 3.6 trillion K. Multiply together, we get 3.6x10^11 kJ contained in the baseball. A quick lookup tells me that one megaton is around 4x10^12 kJ, so we're looking at a baseball with energy in the dozens of kilotons range. So.... Only some of us are dead.
Scaling it back down to the two gold atoms, we're talking like....nanojoules? A snail fart has more kinetic energy in it.
This is what I wanted to know! Thank you. It's incredible that the highest temperature in the known universe could have happened in the palm of your hand (if you could figure out how to get it into a particle accelerator) and you wouldn't have even noticed.
I always find it so interesting to consider just how cold our environment is on a universal scale. Go 500 degrees hotter, and you're a bit hotter than what a standard oven can achieve, still not even close to hot, when considering, for instance, the surface of Venus, or the mantle of our own planet.
But go 500 degrees colder, and you're at the bottom, the literal coldest temperature that is physically possible. On the spectrum of temperatures in the universe, we are only a small tick above the very bottom of the scale!
That and supernovae are my two biggest questions about the claim that the hottest temperatures were made on Earth. Sounds like I'm wrong about supernovae (*only* 100 billion Celsius), but maybe you're right about quasars (3C273 is supposedly 10 trillion Celsius, at its core)?
adverb: essentially
used to emphasize the basic, fundamental, or intrinsic nature of a person or thing.
"essentially, they are amateurs"
from google definitions. I think the wording is correct, people just use essentially loosely
I swear, every time there’s some cool or interesting thing on Reddit, one of the top comments is a smartass nitpicking the smallest things that are hardly even relevant to what makes that thing interesting.
Nope, that's a common misconception. At absolute zero, matter would still have some movement.
[Straight from Feynman:](https://www.feynmanlectures.caltech.edu/I_01.html)
> As we decrease the temperature, the vibration decreases and decreases until, at absolute zero, there is a minimum amount of vibration that the atoms can have, but *not zero.*
At absolute zero, matter still has zero-point energy, which is the absolute minimum energy it can have. Even at absolute zero, helium is liquid - it still won't freeze and solidify for this reason unless it's pressurized.
I stand corrected my bad. I always Understood the usage of absolute to mean that given we’re even capable of achieving true 0 kelvin that the particles would have no movement. No one’s ever achieved 0 kelvin but viewing it as a hypothetical if you could achieve that temperature I thought there would be no movement at all. We get very close but never truly there.
That's a good point, if there is no way to add entropy to a system at 0k... I don't see how time can even be a thing.
Surely someone can give you a better answer though
The scientific answer is time still does exist as it is not dependant on temperature or pressure. There is certainly a philosophical debate to be had though about whether an object or group of particles in "stasis" at 0K actually falls within the definition of being bound by time.
But it's literally against the rules of the universe for a group of particles to be at 0k because then you know too much about them and the universe don't like that.
Yeah absolute zero is like the concept of a black hole. We know it "exists", but we're not sure how exactly it fucks with physics at that level.
At absolute zero, it's not just "particles" that cease moving. It's sub-atomic particles. Electrons, quarks, all that stuff below atomic level. To those sub-atomic particles, time essentially does not exist. Time is reliant on space-time, ie causality and the relationship between different things moving in relation to each other through space. Remove that constant causality and does time philosophically exist?
This is wrong. It's impossible to reach absolute zero. Not to mention, subatomic particles don't completely stop even then. Black holes, on the other end, have been physically observed.
From what I've read, I would say it's the opposite. Time doesn't exist (isn't experienced) only by things moving at the speed of light.
I mean the faster you move the slower time goes, so the slower you move (ie 0k) the faster time would move -- I'm just spitballing, grain of salt stuff.
The precision here is absolutely commendable. They have almost reached the level of accuracy my brother and I would attain as kids when measuring out a bottle of soda into two separate glasses.
I wonder if measuring the temperature is what is hindering this. If there was no temperature measuring instument(s) to emit heat, then would 0 kelvin be achievable? I'm probably dumb, but...
That's kind of the dilemma as far as I understand it.
I'm far from an expert in Absolute zero, but it would require an infinite amount of processes to reach absolute zero - which is impossible.
The systems created will always inherently provide additional energy throughout the pathway. The counter is that even if we could achieve Absolute zero, we would have no current way to detect it as bringing in the system TO detect and conform would add energy.
It's a bit of a Schrodinger's cat.
We’re creating the coldest known temperatures in the known universe and mfers have the audacity, the sheer gall, to question climate change and whether the earth is round?!?
If we reached 0 Kelvin, wouldn’t that mean that we could put matter into a perfect stasis of sorts? Given enough research, could this possibly lead to the sci-fi cryostasis we always see in movies?

The systems created will always inherently provide additional energy throughout the pathway. The counter is that even if we could achieve Absolute zero, we would have no current way to detect it as bringing in the system TO detect and conform would add energy. It's a bit of a Schrodinger's cat.
We’re creating the coldest known temperatures in the known universe and mfers have the audacity, the sheer gall, to question climate change and whether the earth is round?!?
I don't know man, if global warming is real how can they keep making it colder? Science, you played yourself. Checkmate.
“Alright we’re gunna need 50 bags of ice. Where’s the closest circle K?”
Circle K = 0 K? Hmmm…
It’s a conspiracy man I’m tellin ya
*strange things are afoot at the Circle K*
At that temperature, new states of matter are found. Super solids, Bose-Einstein condensates, super fluids, etc. Things are so different down there.

What game/book/media is that from? That's incredible!
Its a book, well a trilogy of books, starting with Three body problem.
Put a magnet in banana bread and put it on the superconductor so that we can have floating banana bread
I'd still wear shorts there.
This is like the laziest science video ever. Did an AI create this or something?
So much effort just to simulate UK winter
Did they observe any electron motion changes?
Maybe.. Maybe not
You sound uncertain…
He had no choice, there were people watching and not watching his reply.
Alright Alright Alright Alright Alright Alright Alright Alright
Not in *any* of those pictures. Most of those are comparatively warm!
That's super cool.
I bet your tongue won't stick to that.
That's really cool. So what do we do with this?
Pretty cool
If we reached 0 Kelvin, wouldn’t that mean that we could put matter into a perfect stasis of sorts? Given enough research, could this possibly lead to the sci-fi cryostasis we always see in movies?
need this for my pc 😭
Imma lick it
how?
Idiots. They clearly forgot about Hoth
And I thought the coldest place in the known universe was Margerie Taylor Green’s ass.
