The Bimetric Theory Of Quantized Fields
We introduce special class of bimetric theories of quantized fields with preserved classical energy conditions. More precisely, we describe the missing anti-particles in our visible universe to be trapped in a spacetime patch with different metric $g_{2}$ ( most likely the de-Sitter spacetime) and negative energies. In order to stabilize these anti-states, time must go in opposite to our visible universe in agreement with Feynman-St\"uckelberg interpretation of antiparticles. Since the energy scale of our observed universe is relatively low, we do not need to worry about these high energetic anti-particles except for compatibility issues regarding the restoration of classical energy conditions. However at quantum gravity scale, these anti-states play a crucial rule in the cancellation of gravitational anomalies alongside with other possible quantum anomalies which may emerge.
