There's some dialogue concerning theories on multiple universes that mentions the universe branching off of choice. It may interest you that this isn't exactly how it works but it can be done. In Everettian 'Many Worlds' you can split the universe by making a choice based on the outcome of a quantum measurement. Measure an up spin and you shave your beard, down and you shave it an hour later: you have just created a universe that is forever changed so long as the you in stick to the decision. There's a good book about this by Sean Carroll called Something Deeply Hidden.
There are apps out there that give you the results of quantum measurements, go forth and multiply universes people ;D
