........................TRINITY................... .... 
It appears that the universe may be eternal, through the operant forces of TRINITY; that being Time, Space, and Motion. The proton may also be eternal, through the operant forces of TRINITY; that being the three quarks. An estimated half life for a proton is 10 years to the 35th power, if indeed it has a half life.
Experimental evidence
Proton decay is one of the few observable effects of the various proposed GUTs, the other major one being
magnetic monopoles. Both became the focus of major experimental physics efforts starting in the early 1980s. Proton decay was, for a time, an extremely exciting area of experimental physics research. To date, all attempts to observe these events have failed. Recent experiments at the
Super-Kamiokande water
Cherenkov radiation detector in
Japan indicate that if protons decay at all, their
half-life must be at least
1035 years.
[edit] Theoretical motivation
Despite the lack of observational evidence for proton decay, some
grand unification theories require it. According to some such theories, the proton has a
half-life of about
1036 years, and decays into a
positron and a neutral
pion that itself immediately decays into 2
gamma ray photons:
Of course the big question is man's life eternal, because of TRINITY???????
