On the Kelvin scale, there is a theory (which some of you may know) in which at -273.16 Degrees Celsius, It cannot get any colder, people believe this is the Holy Grail of cold. Yet my question is, scientests have only been able to get to a picokelvin, instead of (0.0000000000000000000 and beyond forever, AKA absolute zero) I was wondering, What keeps scientests from getting to Absolute Zero?
You're right, it would take somewhat of an eternity to get there, they would have to keep squeezing out every little piece of heat, which takes longer and the amount gets smaller. So I guess we could say we'll never get TO Absolute Zero, but close.
The way I think of it is similar to the way scientists have hypothesized going the speed of light. As you approach the speed of light, you gain evermore mass which requires evermore energy to sustain such speeds. So basically in the end, going the speed of light would give you an infinite amount of mass requiring an infinite amount of energy. The same could theoretically apply to slowing down electrons and molecules to a complete stop. Electrons move the speed of light and its incredibly tricky to control electrons in such a manner. How ever, we've found out ways to slow down light (photons) significantly such a pushing the photons through supercooled rubidium or other materials. If the same sort of background knowledge is applied to getting to absolute zero then maybe progress would be made.
However, I can't seem to think of a use for absolute zero besides possibly implementing it into fusion reactions to cool down the plant (if we could figure out fusion or cold fusion safely in the first place lol).
Well the reason for reaching absolute zero would be to test the theory that when matter completely stops moving it in thought would disappear. Because how humans see light is light bouncing off those moving atoms. if the atoms stopped moving we wouldn't be able to see said object.

That's a silly thought process. Matter won't simply disappear if it stops moving. If matter simply stopped that doesn't mean light wouldn't bounce off it, it doesn't need to be moving for that to happen.

Your argument isn't really correct at all to begin with, but either way, just because we can't see it, doesn't mean it's not there. We can't see dark matter but it makes up 85% of the matter in the universe.
Apart from going to 0K, there is this problem: you wouldn't be able to measure the temperature. Measurements always involve some kind of movement or energy. This means that, if you tried to measure 0 K, you would raise the temperature to above 0 K.

I'm sure they can do the calculations to figure out what temperature the method they used will bring the substance down to.
