US National Space Agency coming summer intends to send a unique refrigerator aboard the ISS, which allow scientists to get supposedly the lowest temperature in the universe.
The device will be delivered to the International Space Station under the name “CAL” – a special freezer with dimensions of suitcase. The atoms inside will be frozen in conditions zero gravity to a billionth of a degree absolute zero according to Kelvin. Recall that a given absolute zero is minus 273.15 degrees on the usual scale for us Celsius.
According to NASA experts, they will receive in this chamber the temperature is a hundred times colder compared to the depths of space.

Project Manager Robert Thompson says: “This experience with atoms is capable of overturning the ideas of science about what is matter, and reveal to humanity the fundamental nature gravity. In addition, the experiment will allow to approach understanding of dark matter, which, as you know, is one and the most mysterious substances in the universe. ”
Thompson explains that when the CAL unit cools the atoms to at such a low temperature, they will create the so-called Bose-Einstein condensate, which is a form of matter with very unusual properties. It will look like gas at the same time and on the liquid, but it will behave like one atom, possessing typical properties of this structure.
The absence of gravity to space will prolong the existence of this condensate tens or even hundreds of times, allowing scientists examine it with all care. True, it is still unknown who exactly will study this substance: the crew of the orbital stations or, remotely, experts on Earth.
