Query: Universal relaxation times for electron and nucleon gases   In this paper we calculate the universal relaxation times for electron and
nucleon fermionic gases. We argue that the universal relaxation time tau(i) is
equal tau(i)=h/m square v(i) where v(i)=alpha(i)c and alpha(1)=0.15 for nucleon
gas and alpha(2)=1/137 for electron gas, c=light velocity. With the universal
relaxation time we formulate the thermal Proca equation for fermionic gases.
  Key words: universal relaxation time, thermal universal Proca equation.
