The second law of thermodynamics states that heat always naturally flows from hotter to colder places. However, in very dilute gases, heat can flow in the opposite direction, from cold to hot. This discovery could reveal cracks in the fundamental laws of physics.
“Given that the second law[of thermodynamics]has been known for 150 years, you can imagine if a counterexample existed.
