I would say...
Every time a decision is made, the universe DOES NOT split.
There are no real decisions made.
Everything in the universe is goverened by scientific principle, which is always predictable.
Everything runs from a start point in a completely predictable path and none of us can alter it.
Every thought we have was predetermined millions of years ago, just as every other single event has been and will be.
Of course it's too complex to actually ever predict or even understand. You'd need a computer as big as the universe itself to model the everything. So it appears we make decisions and there are choices.
But there aren't. Every thought you have is just a chemical reaction in your brain.
So everything runs from start to finish along a predictable, unalterable line as it's all goverened by scientific principles, which are non-random.
