Hi Guys,
After data release of Planck satellite , at least about early universe cosmology, nothing new except few( i.e Dipole asymmetry of the CMB temperature fluctuations ) in comparison to WMAP results was found. As a case existence of non Gaussianity at the level of squeezed limit has been ruled out. On the one hand cosmologists may find that inflationary scenario is on the true line to describe the early universe , specially single field models.On the other hand , it seems that our almost single data of early universe ( Cosmic Microwave background) has been finished! No more satellites for more precise observation of CMB is needed since more pixels doesn't have early universe information and late time effects destroy them in small angles. So, does it mean that the early universe cosmology ( i may compare it with String theory at 2000) suffers from lack of observational data? and what will happen to it? Please let me know your opinions Guys!
