Dear Friends, the 116th finding in my TOU (Theory of Universality) is that the life span of a proton works out to be 3.832 x 10^39 yr; which agrees with the already estimated value of about 3.7 x 10^39 yr , if you take the average energy of an extra-galactic neutrino as 505 x 10^14 eV and based on neutrinos creating time. To be published in the next Annexure.
