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.

Minimum zero point energy derived from uncertainty principle:
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!
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.
The coldest place on earth has the least activity.
Little activity = boring.
We are officially the most exciting and boring place in the universe, at the same time.

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.
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.
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.
Rule 101 of physics is that matter can not be created nor destroyed, so please explain why you are mentioning the "Big Bang" when it is clear that this is just not possible by the rules that govern it?
I would love to read your response or even better, I would love to watch it.
"...but measuring this is impossible; it's forbidden by the uncertainty principle." This is the LEAST scientific thing I have heard on this channel. This makes it sound like this Heisenberg guy carved into a stone tablet "Thou mayest never know the location and momentum of a particle; it is FORBIDDEN!!!" My question, of course, is WHY? If you DID freeze the chunk of lead, and you got it actually cold enough to literally halt all motion in the substance, and you then measured it's location and momentum, would you die? Would it explode? It's weird, because I've heard all sorts of wacky, theoretical ideas from every field of science, a sort of "What if THIS happened?" Look up YouTube videos on "Travelling at the speed of light", another IMPOSSIBLE thing to do, and people theorize about it all the time! But, when it comes to Heisenberg, everyone acts like, "NO! You mustn't challenge Principle of Uncertainty! Lord Heisenberg forbids it!!" It feels... creepy.
If you want to truly understand the Uncertainty principle then read the first and third chapters of the Feynman Lectures on Physics, Volume iii.
If you are interested in understanding Special Relativity then check out this video series
These are among the best educational resources available on these topics. So they are worth going over multiple times till you fully comprehend all the subtleties.
When i heard about this in 8th grade science i was immediately interested because i remember of sub zero from mortal kombat and mei from overwatch and how when we can prosuce this much more maybe we can make meis ice gun. Or maybe.... you know... we can make a badass super solider... just a thought. (I volunteer)
How to become bitcoin trader? Exactly like Bitcoin, multiple digital currencies exist in the marketplace. So if you prefer to buy a few other currencies which aren`t available on Indian Exchange than you can utilize Bittrex. All you have to do is locate an exchange that you favor. Cryptocurrency exchanges have a massive potential to modify peoples minds and opinions concerning cryptocurrencies generally speaking and their application in actual life. So even in the event the exchange is attacked, its still true that you have your money. Furthermore, the exchanges prepare each and every industry for Bitcoin expansion. Existing stock exchanges will also compete to be able to fulfill the users configuration requirements. Sooner or later later on, the prices will grow more equal, meeting somewhere in the middleyour profit is equivalent to the quantity of convergence. No matter how far it is from Kijun, it is likely to return and test that level at some point. The amount of bitcoin is perpetually changing. In the US, it is 1000 USD. Whats even better, seek the services of a seasoned lawyer or at least ask for an in depth consultation. So youve read the newspaper about the meteoric growth of crypto currencies including Bitcoin or Ripple. Then coming up with 1000s of exchange rates simply to go out and get groceries is nearly impossible. Many cities around the world provide a bitcoin ATM where you are able to trade cash for bitcoin. The cryptocurrency world isn`t efficient.
