But that didn’t happen in my world and it can’t, because my world is the world where no one left their phone in 1929.

Yes. There are many paths forward from any moment in time but only one path backwards. That means that to get to where you are right now whatever happened in the past has already happened and can’t be changed.

But that doesn’t mean you’d stay in that branch once you went back and veered off. Apparently you want to think of it like a tree. Thats fine. Sunlight hits leaves on older branches to give it the energy to grow new branches. Energy gathered from the leaves of older branches is used to grow new branches. Not visit and go back up. So let’s say you’re at the top of the tree right now and you travel back and change something, (a new branch) what on earth makes you think you’ll be coming back up the trunk?
