How to understand Vacuum: T=0K ? ==. Physics (classical + quantum) lives under shadow of Vacuum. I want throw light on this Vacuum. Three theories explain the Vacuum T=0K : a) theory of ideal gas because its temperature is T=0K,
b) QED theory because this theory explain interaction photon / electron not only with matter but with vacuum too,
c) Euler?s equation: e^ i(pi) = - 1, because only in the negative vacuum T=0K can exist ? virtual imaginaries particles? which Euler described by his formula: e^ i(pi) + 1= 0.
d) The global conservation of energy is infinite . And this infinite energy belong to the vacuum because that more than 90% of mass ( dark mass/energy ) is hidden in the vacuum How to understand vacuum's infinity ? Vacuum's infinity has only one physical parameter: T=0K. This physical parameter is the key to understand the essence of Existence. =. Without Vacuum T=0K there isn?t Physics, there isn?t Philosophy of Physics. ====. Best wishes. Israel Sadovnik Socratus. ==============.
