What is the coldest thing in the world
Scientists are able to create the coldest materials in the world in physics labs by using laser beams to slow down moving particles. This allows for a better understanding of the inner workings of matter and the development of sensitive instruments, such as atomic clocks and detectors for underground resources. Cold atoms also have the potential to be used in the study of atomic and subatomic phenomena and the detection of gravitational waves.
