The Secret of the Universe

"The Universe surrounding us has been a mystery. How big is the Universe, how is it changing with time, how old is it and what is the Universe made of Cosmology is now undergoing a revolution. With recent precise measurements of the cosmic microwave background radiation, large galaxy redshift surveys, there is now a standard, highly constrained cosmological model. It is not a cosmology that was predicted. Unidentified dark particles dominate the matter content of our Universe, and mysteries surround the processes responsible for the accelerated expansion at its earliest moments and for its recent acceleration. In this talk, we overview the recent progress in cosmology and the present understanding on the secret of the Universe.
