The Quantum Chromodynamics Gas Density Drop and the General Theory of Relativity Ether

? decay is one of the most fundamental and thoroughly studied nuclear decay. Surprisingly, rates were found to have a periodic time variability [1]. However, others argued that there no evidence for such cyclic deviation from exponential first order kinetics law [2]. Here we propose pseudo-first exchange reaction triggered by uddũ exotic mesons QCD gas theory. In analogy atmospheric density, proposed density drops with elevation sun. Accordingly, rate due drop. The may be possible candidate Einstein’s general theory relativity ether [3]. Our main results are derived formulas calculating effective mass cosmology perfect fluid equation state dimensionless parameter, based on measured ratio at earth trajectory aphelion perihelion dates.
