The "god" of WMytheology, namely WM himself, will insist that every such potential string must have a finite definition in order to be thought about at all. > > Regards, WM
Actually, real math suggests that there are reals so incredibly inaccessible that finding the digit sequence representing one of them is not possible.
In which case such numbers may well not be "finitely distinguishable".
