Lowest temperature ever in universe recorded in lab
Scientists at an Italian institute have set a world record of the lowest temperature ever achieved in the universe. They cooled a copper vessel with a volume of one cubic meter to -273.144 degrees celsius. This is stunningly close to 'absolute zero', which is equal to -273.15 degrees celsius. Theoretical physics says that temperature can never go below this limit.
No experiment on Earth has ever cooled a similar mass or volume to temperatures such a low; similar conditions are also not expected to arise in nature. This gives CUORE the distinction of being the coldest cubic meter in the known universe.
The cooled copper mass, weighing approximately 400 kg, was the coldest cubic meter in the universe for over 15 days.
The experiment was carried out under the CUORE collaboration, located at the National Nuclear Physics Institute's Gran Sasso National Laboratory. Gran Sasso is the highest peak in the Apennines some 120 kilometres distant from Rome.
