The Lee-Wick theories require unusual Lee-Wick (LW) partners to the standard model (SM) particles. The excitations of the unusual fields may have indefinite norms in the Hilbert space. In the present talk the thermodynamic results of a toy LW universe (where each normal particle has only one LW partner and the standard massless gauge fields do not appear in the normal particle spectrum as their LW partners has the potential to produce negative energy density) will be discussed. It will be shown that in the LW universe the time-temperature relation gets modified. This time-temperature relationship shows interesting new physics. More over we see how a LW particle dominated early cosmology transforms into the standard cosmology. A brief discussion on the realistic LW universe containing normal gauge bosons and two fermionic partners for each SM chiral fermion will be presented at the end.
