简介: |
Recently, it was claimed that the primordial CMB B-mode polarization was detected by the BICEP2 collaboration. If these signals were all from primordial origin, models of early universe cosmology would be tightly constrained by cosmological observations. I will talk about observational implications on bouncing cosmologies from the combined Planck and BICEP2 experiments. In particular I will focus on three representative bounce models in the frame of matter bounce cosmology. If our universe experienced a bounce, today's observations favor a bounce model which occurs pretty slowly at an energy scale near the GUT scale.
