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.PDF
