Scientists have created the coldest artificial material in history.
We are talking about a cloud of rubidium atoms. Its temperature is about 14 orders of magnitude lower than room temperature and less than the background temperature of outer space. It cannot be created on Earth, so Chinese researchers sent an experimental setup into orbit and cooled the material to 38 picokelvin (a unit of thermodynamic temperature). This is a record that has stood since 2021.
But you'll find out how this achievement will affect science in the AiF material.
