Measuring the decay constant of 87Rb: Is the decay in radioisotopes linear? Manifestation and disintegration of the matter in space-time, and age of the Universe

Abstract

Villa et al. (2015) (Geochim. Cosmochim. Acta, 164, 382–385) proposed a new value of (1.3972 ± 0.0045) (10−11 yr−1) for the decay constant of 87Rb, which according to them is based on the meta-analysis of the analytical data of some experiments conducted by others. In my view their suggested value cannot be considered viable because it is very similar to the one which was discarded about forty years ago, and secondly, for restricting their meta-analysis to only four papers. Therefore, a need is felt to review the literature and take a fresh look at this problem. The paper also discusses some theoretical models for estimating the decay constant of 87Rb; and as per the theoretical model (Gargi, 2012; Chemie der Erde 72, 323–332) the decay constant for 87Rb should be revised to 1.408 (10−11 yr−1). I have also shown that the mode of decay in unstable isotopes is in fact linear, not exponential. The linear decay and other phenomena, such as manifestation and disintegration of matter in space-time, and the origin and age of the Universe are all intertwined. Hence, the evidence for the one is also an evidence for the other. Therefore, the latter two phenomena also would be discussed briefly. The decay constant as measured in the laboratory assuming exponential decay increases with time.
