The Multiverse Explained by David

In quantum physics, information flow in the multi verse is not as tame as in that branching tree of histories i have described. This is because of one further quantum phe mena. Under certain circumstances, the laws of motion allow histories to rejoin, become fungible again. So a natural way to implement it in our fictional multi verse is for the transporter to be capable of undoing its own history, splitting a case. And so the world would be inexplicable to its inhabitants if it were true.
