NASA to create coldest spot in the universe

A new experiment will aim to freeze gas atoms down to a billionth of a degree above absolute zero.
The experiment, which will be carried out aboard the International Space Station, will use lasers and a vacuum chamber to create something known as a Bose-Einstein condensate - a state of matter that can only be achieved at extremely low temperatures.

"Studying these hyper-cold atoms could reshape our understanding of matter and the fundamental nature of gravity," said project scientist Robert Thompson.
"The experiments we'll do with the Cold Atom Lab will give us insight into gravity and dark energy - some of the most pervasive forces in the universe."

The temperature of the atoms will in fact be reduced to such an extent that they will end up more than 100 million times colder than the vacuum of deep space.

Unless some other extraterrestrial civilization out there is conducting similar experiments, this will mean that mankind has effectively created the coldest thing in the entire universe.

NASA Wants to Create the Coolest Spot in the Universe

It's amazing to me that at some level the very instrumentation of the experiment doesn't lend some heat to the project, but this stuff is way above my pay grade. Still it's interesting stuff. If the universe were to expand forever and suffer what I believe is known as a "heat death," would the universe in time uniformly reach absolute zero or is that more of a theoretical number that can be approached but never actually attained?

It seems as if not only can absolute zero be attained but it can also be surpassed! Crazy I know but you might find some interesting facts Here . It makes me hypothesize,  is all matter in the universe actually being compelled towards an absolute negative mass? So instead of dark energy pulling us apart, negative energy is attracting us? A negative space so strong there is no escape? Is that what we can call an area empty of any movement.. absolute negative space? That's how I envisage the edge of the universe to be. The universe has been measured to be expanding, even accelerating, the su... [More]

but why ...

If you'd have read the article you'd know why.

was a different type of 'why'. Under the pretext of understanding physics and space better, we create chemical proprieties that do not occur in universe... why

Why? BECAUSE they don't occur naturally in the universe, It's a a thing called learning. That's no pretext of understanding, it's experimentation which is the very basis of understanding. You really don't understand science at all do you?

Like you do ... this kind of science isn't truly science. its alchemy

You have said a lot of stupid things here but this one takes the cake.  Not only don't you understand modern science, you are ignorant of ancient science.

keep dreaming to green horses spoiled on the walls....
