| Popis: | We introduce a 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 as being trapped in a spacetime patch with different metric such as the de-Sitter spacetime and negative energies. In order to stabilize these anti-states, time must go in the opposite direction to our visible universe, in agreement with the Feynman-St\"uckelberg interpretation of antiparticles. Since the energy scale of our observed universe is low, we do not need to worry about these highly energetic anti-particles except for compatibility issues regarding the restoration of classical energy conditions. However, at the quantum gravity scale, these anti-states play a crucial role in the cancellation of gravitational anomalies, along with other possible quantum anomalies that may emerge.
