Here is a hypothesis: infinite possibility branch theory (IPBT) -- A multiverse concept.
I have been thinking deeply about timelines, probability and then I got a weird thought.
Lets say something has 0.1% chance of happening, normally we say it probably won't happen but then I started thinking: what if that 0.1% outcome actually happens somewhere else?
That slowly made me think of this idea I called "infinite possibility branch theory"
This idea is nothing but every physically possible outcome creates a new branch universe, not just quantum stuff but decisions, random events, chance outcomes etc...
For example :
If I go to a restaurant and there are only three items in menu, burger, piza and salad, let's assume this 60% chance I order burger and 39% chance that I will order pizza and only 1% chance that I will order salad. Then if i order both pizza and burger then that 1% chance of ordering salad made a new branch universe where I ordered salad. Well It's maybe kind of confusing.
Something with a tiny chance happens -- another branch
and every one of those branches keeps creating more branches forever like infinite.
I know this theory some what looked like many worlds theory and branching theory, they mainly focus on quantum measurements, but this one is mainly depends on possibilities, this is where it was different from the rest of other theories.
I also thought about time paradoxes like the grandfather paradox. Instead of changing the original timeline, changing something would just create a new branch universe, so original timeline still exists and there isn't a contradiction.
And another weird thing is maybe there isn't even an original universe, if branching has been happening forever, then every universe could just be another branch and everyone naturally thinks they are in the original one.
I know this is probably more philosophy than actual physics, and I'm not saying I discovered some revolutionary theory, I'm mostly curious.
Like does something very close to this already exists, or does this differ from things like many-worlds in some way?
And I made a hand drawn diagram for visualization hope it maybe usefull for understanding it easily.
And also it's just some weird thought, I just wanted to see what others think about it. And Sorry if there are any mistakes in grammar.
