>NASA researchers are planning to create the coldest spot in the known universe inside the International Space Station.

>Researchers like Thompson think of the Cold Atom Lab as a doorway into the quantum world. Could the door swing both ways? If the temperature drops low enough, "we'll be able to assemble atomic wave packets as wide as a human hair—that is, big enough for the human eye to see." A creature of quantum physics will have entered the macroscopic world.

I'm not sure about that quote. The way its said in the article makes me think that its something that could happen in the future and not right now.

The lowest temp ever created was 100 pK... I think that anyone will have a very hard time surpassing that regardless of location.

lol but to create that doorway, you'd need to make it wide enough we can see it. I think that would be much harder than just creating a very cold spot.

Not really, one of the laws of nature is the law of thermodynamics.

nature's average coldest part is about 3K, many times that temperature. It doesn't very much from that average away from stars, and near stars it goes up

100 PK is their target. I think that the previous experiment proved one could reach that temperature. This experiment is intended to test what would happen at that temperature. Those are different objectives.

That pic is screwed. The pieces in Chinese Chess are placed on the intersections of the lines, not inside the squares. nb

Western audiences wouldn't get the reference using any other board, but the philosophy behind ancient Chinese chess aphorisms remains, hence the disconnect between what is seen and what is heard.
