ISS will soon be the coldest place in the known universe

NASA plans to send a unique scientific instrument "Cold Atom Lab" or "Cold Laboratory" to the International Space Station, which will form within itself the region of space with the lowest temperature in the known part of the Universe. Physicists want to take advantage of the vacuum of space to get as close to absolute zero as has never been possible in experiments on Earth.

This is not done with the idle purpose of setting a record. A series of epoch-making experiments in quantum mechanics and physics by Efimov is planned for the Cold Atom Lab. The latter, in theory, describes the unification at full zero of three groups of particles and the production of molecules from three atoms, which are of enormous size and are very convenient for study.

In 2001, the Nobel Prize in Physics was awarded for obtaining a Bose-Einstein condensate, in which atoms go into a low-energy state and behave like a single wave, rather than individual particles. However, the harmful earth's gravity forces them to settle to the bottom of the tank and there is not enough time to conduct experiments. In space, physicists hope to control the condensate for 10 seconds or more - those wishing to conduct experiments with this "magic" substance are already lining up.

Atoms have almost no entropy, therefore, when approaching absolute zero in the cosmic vacuum, environmental interference is minimized. And different quantum states last much longer, which gives a rare chance to study them "live". Cold Atom Lab is a very complex instrument, the launch of which has been repeatedly postponed, but now NASA is confident that it will be delivered to the ISS within a few months.
