if universe like ours came into being once, and if, indeed, probabilities are to
 blame for its existence, by doing so it has also demonstrated to us, that the p
robability of it happening is not zero. but if so, it has already happened infin
itely oftenand will happen infinitely often again unless, of course, we are livi
ng in a computer simulation, in which it would likely be unfeasible to leave us 
on for infinitely long.does this mean that everything would repeat itself, over,
 and over, and overyes and no. the infinite universes, no matter which model, wi
ll probably not have the same starting parameters. some of them will not be inha
bitable. some of them will be very cold, some of them will have too much energy.
 some of them will be just like our universe. and some of them, well, some of th
em will be the exact copy of our universe, down to every detail.why because the 
reality is quantized everything we know about the universe says, that there is a
 minimum amount of space the planck length and time the planck duration that any
thing can move. particles can only assume discrete quantum states upspindownspin
, etc. they also can not occupy the same position and the same quantum state at 
once. effectively, it looks like reality is pixelated. at the same time, as we h
ave seen with the eternal inflation, there is a limited amount of particles in t
he observable universethe part of the universe that we can interact with. the sa
me is true for a big bang universe, only more soit is born with a finite amount 
of matter.  so the total amount of possible states in our universe is finite. gi
ven infinite time, every possible combination of allowable states will have occu
rred. in fact, it will have occurred  infinitely often.in other words, that girl
 in school who didnt reply your crush in infinitely many universes, the other tw
o of you got married and had kids. in some of them it plaid out exactly like her
e, sentence for sentence, word for word, atom for atom. in countless others, you
 had countless fatal accidents before you ever reached this point in your life. 
you have read this article an infinite amount of times. in some of them, the art
icle might have made more sense.in short it looks like we have been here before.
