    I can at least think of a few counterexamples:

    • Cats live longer than dogs.
    • Small stars live longer than large stars (by dramatic amounts).
    • Black holes larger than the ~10^10 kg mark shown here live a lot longer than any other object with the same mass. A hypothetical moon mass black hole can most likely outlive every single star in the universe.
    • Protons are smaller than anything in this chart yet are believed to decay over an extremely long time scale (>10^34 years).
    • Even smaller particles like electrons likely live forever.

      Those particles are exactly the kind of exception I was looking for. Tiny things that last a long time. The opposite kind of exceptions are probably impossible since making large things takes a lot of time. You would need to have something the size of a galaxy that lasts from Monday evening to Thursday morning.
