Is it ever physically possible for a broken egg to reassemble into an unbroken one?

And if you do Planck length accuracy that 10^38 turns into 10^70, so the volume turns into 10^210. The approximation I made at that point put the volume less than 10^1000.  The rest was taken into account in my calculation. Yes, that 1 proton difference was taken into account by my raising things to the power of the number of particles in the universe. Each different arrangement would be different and I picked out the one that it actually is.

The other properties, again, add a few to the exponent but won't get it up to a googol.

I'm not convinced that you're mathing it right.

A standard deck of playing cards has 52 cards once you remove the jokers, so there are 52! or ~ 8*1067 possible combinations, each of which is equally unlikely.

One mole of water is 18 grams, or just a bit more than a tablespoon at STP. A random arrangement of the molecules produces 6.022*1023! possibilities, which is a bit better than 10^1025. That isn't a googolplex but it's headed the right direction and we've gotten that far by just by arranging the molecules in a simple random array. It doesn't take into account any of the properties of the water molecules or their interactions and certainly doesn't account for iteration over time. Factoring in space at nanometer scale and time on a nanosecond scale seems to yield ~10^1055 possible arrangements per mole per second. Given that we still haven't factored in a lot of the properties of the molecules or any of their interactions it seems likely that we can beat googolplex odds with a pint of beer. If I haven't mathed it wrong, which is very likely.

The observable universe has roughly 1080 fundamental particles and the factorial of that is just shy of 10^1082. Still not a googolplex but much closer and that is just lining the particles up randomly with no accounting for spatial or temporal resolution, much less any of the more interesting attributes and interactions of some of those particles. Given that many permutations as a starting point and adding in spatial resolution at even the light year scale would appear to topple googolpex odds every moment of our existence.

I'm not sure why you think a complex irrational to the power of a complex irrational has to be large at all. For example, e^(i\pi) =-1, famously.

I wasn't trying to make it big, I was trying to make it horrible. In some very special rare cases it resolves to a sane number but typically you end up with horrid endless series of fractions. Like this little horror:
