Maths HEP Lunchtime Seminars: Observational equivalence of conformally related frames

Presented by Misao Sasaki, Yukawa Institute Kyoto University

30 April 2010 13:00 in CM221

When applied to cosmology, this allows an extremely unconventional, apparently controversial picture that our universe may not be expanding at all. I show how such a picture of the universe can be observationally consistent.
