Susskind's interpretation of QM
Leonard Susskind often states that he disagreed with Stephen Hawking on black holes dynamics, based on his intuition that information must be conserved.
In quantum mechanics, the Schrödinger equation is unitary, and therefore time reversible and deterministic.
However, when a measurement is made, the wave function collapses and these properties are lost, at least in the Copenhagen interpretation.
Susskind's belief that information is conserved must imply that he believes that the global wave function of the universe obeys the Schrödinger equation?
Is this right and has he stated this position explicitly? Where does this place him with regard to many-worlds and other non-orthodox interpretations?
