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.

Hank, u gotta go out in sunlight, take a deep breath, then activate ur photochemical Green chlorophyll bc it is not degree Kelvin, just Kelvin
-
I heard that when rubidium approaches absolute zero it likes to screw with gravity and drag space around with it. Is this true?
-
Can 10 trillion degrees celsius burn every single substance in space?
-
So if absolute zero, or 0 Kelvin, is the minimum motion, what is the name for the complete absence of motion even to the subatomic level? What would we measure that as? Negative kelvin?

I knew vsauce2's video reminded me of something .. 4 years later
-
Actually, they did get them to Absolute Zero.
-
I guess you could say, we're the coolest planet in the universe?

Why would the uncertainty principle have to keep being true at all times ? Is it that far fetched to think that it has an excepting in considerably extreme conditions ?
Like if he said "We can never know both the speed and the position of a particle, except of course at absolute zero because there is no movement so no speed", it would have sounded logical. -
Means electrons of atoms freeze their motion?
-
isn't helium liquid point at 0,5K or something?
-
What i would really like to know (and there may have already been a video on this) is:
1. How EXACTLY was the temperature of absolute zero ascertained? (like how exactly did they come up with figure of -273.15°C?)
and 2. How EXACTLY was the speed of light ascertained?
A brief scetchy response to my first question was given here but I still don't see exactly what methods, materials and calculations were undertaken in the 19th century with only relatively primative equipment.
Similarly I understand that the speed of light was determined before even absolute zero with even less technology and even as much understanding of how the universe ticks as we have today in the 21st century. -
Elude, not allude in the subs.

There is no such thing as "0 degrees Kelvin", genius. Nor is there such thing as "X degrees Kelvin". KELVIN DOESN'T USE DEGREES. WHY ARE YOU TRYING TO SCIENCE??????
-
HOW CAN GLOBALWARMING BE TRUE IF EARTH IS THE COLDEST PLACE IN TH UNIVERSE> THAT IS JUST ENTROPY
-
You have been saying 2.7° K... but it's just 2.7 K and not degree K!!!
-
I FULLY agree with the uncertainty principle.
-
Is this john green?
-
This would make Elemental Hero absolute zero card's effect make sense

I hated this video
