Warmth at all times spontaneously flows from a warmer place to a colder one – so says the second legislation of thermodynamics. However inside an especially sparse fuel, the alternative could also be doable, with warmth flowing from chilly to sizzling. This discovering may reveal cracks in a foundational legislation of physics.
“Given the second legislation [of thermodynamics] has been identified for 150 years, you’d think about that if a counterexample exists, then…
