Scientists Reach The Coldest Temperature Ever

There is no upper limit to hot something can be. If you keep adding more energy in a fixed volume it will keep getting hotter and hotter. Even the early universe was Trillions of degrees hot.

However this can't be said about the cold. As we take heat away from something, it begins to get cold. But there is a limit to how much heat we can take and after a certain point, there is no heat left to take as there is no atomic motion left in the object and that is called Absolute zero temperature, -273.15 °C. It's almost impossible to reach the -273.15 °C mark because we can't take all the kinetic energy from atoms.

Scientists in Germany conducted an experiment. They took 100,000 rubidium atoms trapped in a vacuum and cooled them down to form Bose-Einstein Condensate (BEC) where all the atoms began acting like one big atom. Then scientists began switching a magnetic field until the atoms came to an almost complete standstill reaching the coldest temperature ever recorded. A chilly 38 trillionths of a degree above absolute zero.

Started reading the book 'Baby Universe'. The complex things are explained in such a simple and attractive way! Thanks a lot for this amazing book!

Scientists: *Creates the Coldest Temperature Ever.*
Antarctica: *Look how they are mimicking a fraction of our power.*

Imagine if the coldest temperature would be used as an execution, the cold is put into your blood and then it shuts down the organs very fast or kills all the brain cells within a second after putting painfully, would be painless, only 1 second of cold pain

I was just studying that we have never attained absolute zero in laboratory and mr scientific posted

Let’s face it… Mr Scientific teaches us more than school ever did

[lratio]

Btw whats this whole experiment named?

[yabetsa]

Sir have you ever heard about the planck temperature? It's about 1.42*10^32 degrees and is actually the upper limit of temperature in theoretical standards this temperature is so hot it may have enough energy to melt atomic particles and ironically, some sources say this was the universe's temperature when it was about 10^-42 seconds old.

I learned during my high school that evaporation causes cooling. how tf we are able to reach those extreme negative temperature. Is there any other method/ phenomenon to cool a substance?😬

[exeebapg]

From where do you all these topics and information?

[quizo]

That's a wonderful achievement!
Proud for the scientists 👏👏
And it's cool too!

[chiragrnayak]

Amazing video and very good information . Thanks Mr scientific

People 1000+ years in the future: "ARE YOU SURE ABOUT THAT?"

[yeenokzhang]

0:02 actually there is something called planck temperature where the molecules are moving at light speed which means that is the hottest temperature possibld

I really got motivated abt learning the universe and it's origins from this channel

[arijit]

I have noticed lot of times that people often subscribe to knowledgeable channels like getsetfly, facttechz, antariksh tv and of course mr scientific but they don't watch it
And it is normal for informative/educational channels to get less views becoz audience always like to watch comedy, roasting etc., actually comedy nd roasting is not bad but unko aise bhi videos dekhne chahiye
But aise videos dekhne ke bajaay log faltu wali videos dekhtey hai
I really feel bad for such creators who worked very hard for giving proper knowledge to their audience but audience ko nakli hee dekhna hai
But all u creators keep working hard, aap logonko kam views milte hai kyunki sabke paas itna knowledge lene ki utsukta hee nahi hoti hai, sabko sirf roasting and comedy dekhni hai

Mr Scientific gives more information to me, I want to support him definitely. 🙂🙂

Can u tell what was the final temperature? In celcius ??

[SteveFrench_]

Absolute zero is impossible to achieve. As you stated, at 0° K, the atoms have lost all of their kinetic energy which would allow us to know an atom's location and momentum, which, according to Schrodinger, is forbidden. As far as hot, when you add energy and it gets hotter, the waves of the radiation get shorter. Eventually those waves will shorten to the Plank Length, the shortest known length. That temperature is the Plank Temperature and no one knows what would happen if we added more energy to the Plank temp.

Things started to get a little chilly so they threw in some fire music to heat things up at bit 😎😂
