If it's known that the planck lenght represents a very "small" dimension where the laws of physics cease to operate (although we cannot know what happens to reality on such small dimension), there must exist an equivalent point where the observable universe will expand into such a big spatial scale that the laws of physics also cease to operate.

And a recent study about the potential lifetime of photons showed that light particles can last a billion of a billion years.

So my question is this: assuming that a single photon will have a "lot" of time to reach a point where the universe spatial expansion causes the laws of physics to "end" in a way that could be similar to what happens at dimensions "smaller" than the planck length, can we speculate that a "single" photon of "our" observable universe may carry enough energy to generate another big bang relative to dimensions that are much "smaller" than the planck length ????

I ask this question because I cannot believe that there is a scale "limit" on how small or big reality can be, and I just recognize that the laws of physics cannot apply on the very big or very small scales, so it's absolutly natural to imagine that a tiny ammount of energy in "our" observable universe could be a "colossal" ammount of energy for scales that are much smaller than the planck lenght.
