In our models, we're really taking seriously this idea at thee's that there's branching as a result of these epossible orders of up dating and so on. But for us, it's very important that the paths of history can branch and they can also merge. They merge when two a two outcomes for the universe end up. You apply two different rules, and it so happens that they end up with an identical universe. So in other words, even though you thought you were going to go in two different branches of history,Even though for a while you've got two completely incompatible structures of space time, in the end they will merge. In the end there'll be and that's
It’s not easy, figuring out the fundamental laws of physics. It’s even harder when your chosen methodology is to essentially start from scratch, positing a simple underlying system and a simple set of rules for it, and hope that everything we know about the world somehow pops out. That’s the project being undertaken by Stephen Wolfram and his collaborators, who are working with a kind of discrete system called “hypergraphs.” We talk about what the basic ideas are, why one would choose this particular angle of attack on fundamental physics, and how ideas like quantum mechanics and general relativity might emerge from this simple framework.
