In a breakthrough discovery, researchers have used sophisticated instruments to measure the temperature of individual atoms for the first time. By analyzing a single atom, researchers were able to determine that the temperature of the atom was colder than the temperature of a blackbody, a theoretical object that absorbs all incoming radiation and reflects none of it. This finding opens up new possibilities for exploring the properties of cold atoms, which could lead to a better understanding of quantum physics.
