The universe is a giant heat engine: its expansion, like a piston, does work. Scientists calculated the efficiency of this 'motor' and confirmed that it doesn't break the laws of thermodynamics—alas, you can't build a perpetual motion machine even out of the cosmos.
🎯 The cosmic horizon isn't just a geometric edge: it has a temperature, like a heated body. This makes gravity a part of thermodynamics.
