Decay (Expansion) of the Universe and Stability of the Solar System in a Fundamental Quantum Description

The expanding (decaying) universe is discussed in the framework of a local quantum field theory, based on a Lagrangian, in which all fermion operators are coupled to bosons. In this formalism the initial phase of the universe has been explained by creation of particles out of the vacuum, accumulation of a system of large mass and immense radius dominated by (e−p+) and (e+p−) pairs, followed by a chirally triggered collapse and annihilation of all (e+p−) pairs (antimatter). The resulting annihilation photons led to strong heating and disintegration of the remaining (e−p+) pairs (matter) during the ”Big Bang”, resulting in exponentially increasing velocities of the decay fragments towards large radii (accelerated expansion). A good description of velocity-distance data from supernovae Ia observation is obtained by adjusting the position of the Solar system to a radius of the universe of ∼ 1200 Mpc. Of importance, at this radius the repulsive and attractive forces compensate each other. Combined with a calculation of its mass, this yields surprising evidence for a stable Solar system and most likely also other cosmic systems, which do not follow the general expansion of the universe. The accelerated expansion interpreted in cosmological models as due to unknown dark energy is understood by the strong radial fall-off of the gravitational potential generated in the early universe.
