The Geneva Symmetry Group, Beyond Spacetime, and the Space and Time After Quantum Gravity Project are happy to present
Tatyana Shestakova (Southern Federal University, Rostov-on-Don):
Could the Copenhagen interpretation be useful for our understanding of Quantum Cosmology?
Wednesday, 5 October, 18:00 (note the new starting time!)
Room L107 at 2, Rue De-Candolle
Anyone who wishes to attend this talk is welcome. The talk will be 4 Einsteins (out of 5).
Abstract: It is generally accepted that the Copenhagen Interpretation is inapplicable to Quantum Cosmology, by contrast with the many worlds interpretation. I shall try to demonstrate that the two basic principles of the Copenhagen interpretation, the principle of integrity and the principle of complementarity, do make sense in Quantum Gravity, since we can judge about quantum gravitational processes in the very early Universe by their vestiges in our macroscopic Universe. I shall present the extended phase space approach to Quantum Gravity and show that it can be interpreted in the spirit of the Everett’s “relative states” formulation, while there is no contradiction between the “relative states” formulation and the mentioned basic principles of the Copenhagen Interpretation.
