ABSTRACT- 2015 signifies several milestones in physics. James C.Maxwell showed 150 years ago in 1865 that light is a specific form of an electromagnetic wave that moves in free space. The relativity principle of Albert Einstein stating that nothing can propagate faster than light in free space eventually led 100 years ago in 1915 to the formulation of General Relativity Theory. The discovery of CMB radiation at 2.7K 50 years ago in 1965 is taken as direct evidence for the beginning of our Universe with a Big Bang. It was realized at the turn of the 20th Century that only unknown sources of Dark Matter and Dark Energy over ordinary matter in the Universe can explain its present-day expansion at an accelerated rate. I will summarize briefly some current ideas in Cosmology and Cosmogony. Then say a few words about possible evolutionary patterns of our universe into the future.
