After 100 Years of Debate, Hitting Absolute Zero Has Been Declared …
While scientists have long suspected that there’s an intrinsic ‘speed limit’ on the act of cooling in our Universe that prevents us from ever achieving absolute zero (0 Kelvin, -273.15°C, or -459.67°F), this is the strongest evidence yet that our current laws of physics hold true when it comes to the lowest possible temperature.
Second Law of Thermodynamics
Researchers at the US Department of Energy’s Argonne National Laboratory say they might have discovered a loophole in the Second Law of Thermodynamics, where the march of entropy can go in the opposite direction – on a microscopic scale, at least, and only in the short term.

Absolute zero – Wikipedia
The laws of thermodynamics indicate that absolute zero cannot be reached using only thermodynamic means, because the temperature of the substance being cooled approaches the temperature of the cooling agent asymptotically. [4]

Physicists prove that it’s impossible to cool an object to absolute zero
(Phys.org)—In 1912, chemist Walther Nernst proposed that cooling an object to absolute zero is impossible with a finite amount of time and resources. Today this idea, called the unattainability…
