Ponderings: The Multiverse

I'm a believer in the multiverse theorem that there exists an infinite number of universes where each universe is slightly different than the next. These differences can be as small as one person decide to have soup instead of a salad for lunch one day or as large as the speed of light being different then our own. In the multiverse everything and anything is possible because in an infinite number of universes, expecially how large and varied ours is anything can happen.

When thinking about the multiverse I stumbled upon the question of "Is there a universe where everything is exactly the same as this universe with the only difference being that it is an hour slower then ours." This being that from start to end these two universes are the exact same with the only difference being that one started before the other. If this is allowed into the equation then that means that every second this universe is being created and ending at the same time across the multiverse. However jumping down a few levels into the fourth dimension (time) a quote comes to mind.

Time is relative and we can only observe it in slices. Now I've been thinking about when universes are born in the multiverse. Are they created every second when the possibility of chance comes into play such as is another universe born if we decide to sleep in one day and in the other we don't. Now this kind of thinking can make sense if our universe gets split into thousands upon thousands of multiple universes every hundred millionth of a second to cover all possible alternatives for everything that could happen. However I don't like this idea that much since time is relative and therefor doesn't even enter into when a universe is added to the multiverse.

What I believe is that instead of splitting from each other they all start out from the beginning and play to the end of their existence. So all possible universes in the infinite numbers of the multiverse, they all exist at the same time and since time is relative every point in their histories also exists at the same time when viewed in such a manner. So instead of there being an infinite number of the same universe where the only difference is when it was made you would instead be looking at the same universe along different points in its history.
