Hank explains absolute zero: -273.15 degrees Celsius - and the coldest place in the known universe may surprise you. A correction on our use of the phrase "degrees Kelvin" can be found in this video: http://www.youtube.com/watch?v=OA98hl7Q5dQ - beginning at 6:43.

I would be very cautious trying to get to absolute zero. There is a lot of energy left in atoms. What happens if the molecules can't move and the energy is not trapped within the atom anymore. Where does that energy go?

Take any substance to Jamaica and give it some weed and a Bob Marley CD... It'll get to absolute zero instantly. But seriously, I'd prefer to use Kelvin than Celsius.

Can anyone explain me why 0K is the lowest theoretical temperature which is equal to -273°C...

Is heat a by product of motion? If this is true this explains why no one has or ever will be able to get to -459.67 degrees F. You cannot stop atoms from moving you can only slow them down or speed them up. Minimum movement is still movement thus heat is still being created. I think the scientist trying to accomplish this feat are just chasing their tale for answers that have already be solved. IMO
James Luqqy (2 месяца назад)
So im confused. Is outer space ambient temperature absolute zero considering nothing is there creating any kind of heat? Im really confused. Whats to say thats the coldest it can get anyway if no one can even reach it. How could anyone even know that?
Juan Camilo García (3 месяца назад)
Is there a maximum temperature? I always thought no, but if it is kinetic energy, and particles are bound to a maximum speed, then there should be right?

The real cause of the Mandela effect >>> water has memory and it holds it in its magnetic field, scientists say a black hole at the point of no return could hold a copy of everything that falls into it, this is one of the half-truths, just like waters magnetic field holds memory, earth magnetic field hold our memory’s and reality, CERN's powerful magnets being turned on and off in a sequence is creating a magnetic field frequency, just like the big blue spiral that was recorded and put on YouTube, a magnetic field can affect other magnetic fields creating a new magnetic field and this is how they are changing our memory’s and reality’s, the supercomputer ( the D wave) works out what combination the magnets need turning on and off to know what effect it will have on our reality, CERN creates this magnetic fields, then chem-trials help to carry and implement the new frequency into earth magnetic field causing all these changes. The rockets that have been seen over the United States is also carrying a magnetic field and implanting it into earth magnetic field creating a new magnetic field which is new realities and memories. This is just my belief but with scientific examples to support it. If this is correct then is their different dimensions or are we still in the same one but mass memory has been changed as well as our reality??? See all that would be happening is the magnetic field would be changed slightly, it would still be the same one, just changed. This would be showing that mass mind control is being done and anything in the matrix can be created just like a computer programmer can create anything on a computer, you want a Jurassic Park full of dinosaurs, then what’s to stop it, you want an Empire State Building made of solid gold, just program it in, you want a world with no poverty, just program it in, you want to create climate change just program it in. Do you see the possibility’s of this, anything that can be thought of can be created? This needs really looking into so please share it as much as possible.

If it could happen, what would happen if you went below 0 kelvin
kieran O'dea (4 месяца назад)
Absolute zero can be lowered, when you factor in time. The colder it is the faster a warm substance will have its electron's stop moving. At the top range it may take several seconds but in the lower ranges it can happen all most instantly. So there is no set temperature that's the lowest, you can all ways get colder when you record the time it takes to bring a substance's electrons to a stop.

You simply cant cool anything to absolute zero not because quantum (synonym to I don't know or I'm not sure) but because it is impossible while there is energy, when energy is all lost it will be absolute zero. Once there is no more energy, well there will be nothing and no one to worry about temperature.

I think I can get it closer on average. I can make something minus x Kelvin for a certain amount of time, and then I'll use some time it was above zero Kelvin. Then I calculate in what time range this was on average exactly quite close to 0!

Hey is it 273.15 but in my book its 273.16
Al Rats (7 месяцев назад)
Absolute zero is -273.15 °C. However, the size of the Kelvin temperature unit is determined by dividing the temperature range between Absolute zero and the triple point of water by 273.16. In other words, the triple point of water is defined to occur at exactly 273.16 K. The triple point of water occurs at 0.01 °C. https://en.wikipedia.org/wiki/Triple_point

It kinda frustrates me that lots of pop sci shows/channels/etc oversimplify the uncertainty principle: they seem to imply that there is a measurement that we can simply not make... (As in- to measure something to a certain degree changes it so our knowledge of such is thus limited) this is not the case. The fact of the matter is that that there IS NO specific thing/position/vector/momentum/etc to measure beyond a specific point! Its not that we cannot see 'this or that' quantity... it's that 'this or that' DOES NOT exist !just saying.

So the coldest planet is -272 degrees. Am I right?
TheGreatSeraphim (8 месяцев назад)
The uncertainty principle is not a thing. It's a simple matter of the moment you try to measure something you are applying energy/force to it, removing it from its original state. Same thing with measuring light. You measure light with light, by the time the light returns to the sensor where the light is, is as far as away from where it was when it was measured as the distance from where it was measured to the sensor plus all the computational bits. We'll always have a bit of lag till we find a way to get around the forces of the universe that act upon our measurements.
Al Rats (7 месяцев назад)
The Heisenberg Uncertainty principle is very much a thing. If you're interested in understanding what it states, then read the first and third chapters of the Feynman Lectures on Physics, Volume iii. http://www.feynmanlectures.caltech.edu/III_01.html http://www.feynmanlectures.caltech.edu/III_03.html

its interesting to say you can't freeze an atom to be motionless because of some rule that says you can't know particles positions and speed. Clearly one does not prove the other.

Of there's 0 energy at absolute 0, doesn't that mean there's no mass?
