"The existence of this radio to the past" creates the possibility of new
paradoxes, now in the classical domain. In particular the
unproved theorem paradox [2] can arise. Bob reads the
proof of a theorem in a book and uses the set-up of Fig.1
(top panel) to send it back in time to Alice. Alice sub-
sequently publishes it in the book from which Bob will
read it. Where did the proof come from?"

Problems with modelling closed timelike curves as post-selected teleportation

In this comment on S.Lloyd, et al, Phys.Rev.Lett. 106, 040403 (2011), we show that modeling
closed timelike curves (CTCs) as post-selected teleportation allows signaling to past times before
the creation of the CTC and allows information paradoxes to form.


TC Ralph above is wrong in his last sentence. Seth Lloyd is correct.

This is precisely how new ideas are always created in the human mind.
Indeed this is the basis of Penrose's objection to "strong AI".

The evidence is there in Libet ---> Radin et-al ---> Bierman ---> Bem.

The analogy here is to Einstein's recognition of the invariance of the vacuum speed of light.
Einstein realized that simultaneity is not invariant under observer motion transformations.
Physics in 1905 fell into place with that insight. Similarly, recognizing that the above "paradox" is not a paradox, but is, in fact, how things are - the mystery of conscious creativity falls into place with a Gestalt Shift. This is all part and parcel with entanglement signal nonlocality with orthodox quantum theory as a limiting case of a more general post-quantum theory.
