Theoretically there are an infinite amount of universes with an infinite amount of different ways our lives could've played out. But what if the amount isn't infinite, but instead diminishes as time moves forward? What if those universes are just the decisions we haven't made yet because the progression of time hasn't reached them?

Think of it like a zipper in your jacket that's zipped midway and that you are the pull tab. As you zip upward, you move forward in time and the past behind you locks together, just as both sides of the zipper come together and close.

You look to the past and see this straight line of decisions you've made that has led you to this point in time. But that line divides as you look ahead with the infinite amount of decisions you have the potential to make.

In the past, there was an infinite amount of universes of different things you could've done. Each one of them playing out, as you come closer to deciding. But since you've already made a decision, you have erased the possibility of making another decision in that point in time, therefore erasing the existence of that universe. That concept of erasing those universes from existence is the closing of the zipper as both sides come together to make a single straight path.

As you look ahead, the zipper opens. Leaving an endless possibility of different outcomes to occur. As we move forward in time, we just keep erasing these pieces of infinity until it all becomes one straight line, and there are no longer any more universes.

That's not to say that the end of your life means the end of possible universes mankind can decide from. We all are just little tabs riding up a split zipper making it close the farther in time we go, killing off the amount of universes that exist with it. But who knows. I'm just someone posting on /sci/ because I'm bored. Feel free to destroy this theory however you like or discuss or add more onto it. I'd like to know what you think
