The two universes are coupled with transformation t to -t. It is shown that for Planck scale the oscillations of temperature of the universes are observed. For the Mirror Universes the temperature fields are shifted in phase. Key words: Gravity; Universe temperature; Oscillation of temperature.2 pages, 2 figuresGeneral Relativity and Quantum Cosmologytext
