The scoring pass in football of a prima donna is a nice analogy for Libets tests!!
If we live inside one bubble of a 12 fold super ( Charge Parity) symmetric multiverse, entangled down to each quantum, then according to Benjamin Libets measurements, there is always one person who is the prima donna by makeing a scoring pass, which should be approved by all other players without "veto" interference.
So the multiverse is not exponential growing with every collapse of the wavefunction, in a finite symmetric multiverse, only one outcome happens symmetrically, in an anti matter universe and a material universe.
