How do you calculate this rate of decay. Do all protons share the same half life or is it averaged? Very interesting thoughts
At this stage it is all just theory, not actually confirmed that protons even decay! It is generally thought that they do, calculations from the most widely understood Grand Unified Theory (GUT) put proton decay (half life) at 100 thousand billion billion billion years. Due to how long it is though, it has never been observed so we therefore have no actual evidence of it happening.
