Most theories that go beyond the standard model of particle physics predict the decay of the proton. The standard model has a LOT of strange complications that are explainable by the more extensive theories, so the prediction of the decay of the proton is a fairly good bet. But the lifetime is NOT well predicted given the variety of possibilities. Also, a proton decay has never been observed.<quoted text>
Hey poly a question for you,
The supposedly end result of universal entropy (entropy of the universe) is that all matter and energy will slowly diminish to nothing and the universe will not exist.
Some believe that since they found the half-life of a proton the "black death" of the universe eventually occur. It will be billions of years coming though.
According to some such theories, the proton has a half-life of about 10^36 years, and decays into a positron and a neutral pion that itself immediately decays into 2 gamma ray photons.
What are your thoughts on this?
So, at this point, we do not know.
