Is the Universe not old enough for the decay of single proton?

    Sort of, but not really.

    Quantum decay is probabilistic. A "half-life" is the length of time over which the odds of the decay of a single particle is exactly 50/50. But any given individual particle could take many times that long to decay, or it could decay in no time at all.

    There is literally no fixed length of time that is too short for a single decay to be possible.

    When driving toward the Lawrence Livermore labs I saw a sign along the road that said: "Watch for falling rocks due to proton decay".

    We haven't checked them all. I personally haven't checked any, in fact.

    They can not Physically decay by themselves

    A single proton decay has not been observed yet. Scientists believe it would take several trillion years to have a complete decay. A proton's half-life is a little less than 3 trillion years, so it needs many half-lives to completely...."vanish".

    A proton that becomes a neutron in a nucleus of an atom (by releasing a beta + or positron), is not considered a decay for it is always inside the same atom and is interacting with the other particles there.

      Well then we'll be watching for a long time to see a proton decay.

    Didn't know all protons have decay. I mean some decay in no time, others, maybe never.
