Bounce Scenarios in Cosmology

Conference Date: 
Monday, June 26, 2017 (All day) to Wednesday, June 28, 2017 (All day)
Scientific Areas: 
Cosmology

 

In standard cosmology, the history of the Universe started with an initial big bang singularity where the description by general relativity breaks down. This basic incompleteness of cosmology suggests the need to go beyond general relativity, or beyond matter satisfying the Null Energy Condition, in order to account for the origin of the Universe. An attractive possibility which has gained popularity in recent years is to replace the big bang by a bounce, in which an expanding Universe emerges from a prior period of contraction. This workshop will bring together researchers who have developed different types of bounce scenarios in cosmology. Focus points of the workshop will be comparison of foundations of the different approaches, discussion of conceptual questions, such as whether a classical description of a bounce can make sense or quantum mechanics is essential, and relation to cosmological observations, in particular in light of the usual claim that physics at the big bang is observationally irrelevant.
