Okay, so we know roughly that there are around 10^89 protons within the universe.

Now lets say that at the point of T=0 any possible outcome was possible but that the initial inflation/BB then set the universe into a pre-determinable course (that is if you could hyperthetically do away with the uncertainty principle)

My question is. mathematically what would you say that the number of possibilites are at T=0. What are the number of possible outcomes. Think about outcomes such as a universe where my front door is green instead of the colour white, which it is. Or another possibility maybe that i have one less atom in my body than i do. Or that a football field has one blade of grass less than it does, or even one of the blades of grass has one atom less than it does.....I hope you know what im getting at here.

The possibilities are definately NOT infinate, as there our universe IS finite. So my question is, at a guess, how many possible possibilities in difference are there ?
