Abstract:
The greatest challenge for any theory of the early universe is to explain how the universe became homogeneous, isotropic, and spatially flat. These conditions are unexpected after the universe emerges from a big bang. Inflation was invented to solve this problem, but does inflation actually work? And is there an alternative?
Event Organizer: Dr. Tobias Holder
