It is easy enough to show that uncountably many of them do describe paths. An alternate way of describing an infinite path is as an infinite binary sequence of left o right branchings. It should be clear even to someone as mathematically handicapped as WM that there is an obvious bijection between the set of paths of a Complete Infinite Binary Tree and the set of all infinite binary sequences of left o r right branchings.
And Cantor has shown that the st of all infinite binary sequences is uncountable. For every different subset of nodes which is a path there is an infinite binary sequence different from that of any other path and every infinite binary sequence determines a path different from that of any other infinite binary sequence. > > > > I believe the proofs that no set can be surjected to its power set are > > valid, and will continue to believe it until I see an EXPLICIT > > surjection from some set to its power set. > > You could also require an explicit bijection of the set of unicorns to > the naturals - otherwise you are convinced that there are uncountably > many unicorns.
Since unicorns are not a necessary part of the world of mathematics, I will leave all conjectures about them to WM. > > > > You > > > will never gather more than countably many infinite paths. > > > > Then we will never access all of the Complete Infinite Binary Tree, even > > though it does exist. > > Where?
