Ludwig Boltzmann - the author of statistical Thermodynamics - discovered a simple law that postulates the high probability W of the real existence of Entropy S of the thermal energy of all bodies of the Universe = Analyzing the properties of the "New Ether" - cosmic microwave background radiation - [2], the author of this book discovered signs of the real existence of Counter-entropy - = - which replenishes the loss of thermal energy (Entropy S + Counter-entropy - S ) = 0 and thereby eliminates the danger of thermal death of the Universe.
