Wave function discord
Abstract
Linde's proposal of a Euclidean path integral with the ``wrong'' sign of Euclidean action is often identified with the tunneling proposal for the wave function of the universe. However, the two proposals are in fact quite different. I illustrate the difference and point out that the recent criticism by Hawking and Turok does not apply to the tunneling proposal.
