Chinese scientists have achieved the lowest temperature ever recorded, cooling atoms to 10 picokelvins above absolute zero aboard the Tiangong space station. This was accomplished using optical tweezers to trap 20,000 rubidium atoms, significantly reducing their movement in a microgravity environment. The results may enhance future space research, particularly in quantum simulations and precision measurements. However, reaching absolute zero remains theoretically impossible due to the third law of thermodynamics, which states that particles retain some entropy. The experiment builds on previous work done on the International Space Station, where temperatures of 52 picokelvins were recorded.
