Abstract
 
In this talk, I will review the tensions in standard cosmology. These are temporal tensions e.g. present Hubble parameter H0, time evolution of Hubble parameter H(z) and BAO distances around z=2.5 as well as spatial anomalies e.g. CMB dipole, quadrupole and octopole alignment and ... 
Then I will study a new model of dark energy based on Landau-Ginzburg idea for the phase transition. I will show that this model can remove H0 and Lyman-alpha BAO tensions. More interestingly, our model our model provides a natural framework to study the spatial anomalies of CMB. Up to our knowledge it is unique for this reason.  سخنرانی عمومی در تیرماه...
