"A Brief Tour of Big Bang Cosmology"
Abstract
The story of our Universe, from its beginning to its end, has always intrigued mankind throughout history.  Trying to address some of the really big questions about the structure of the Universe - how big is it? how old is it? what is it made of? how did the Universe begin? how did we get to where we are today? what is the fate of the Universe? - we have come a long way towards understanding the structure and dynamics of our Universe.  Starting with the age-old question of `why is the night sky dark?', this talk will present a brief journey through the Universe, from its beginning to its possible ultimate fate, painted with a broad brush.  What we know about the expansion and age of the Universe, Einstein's General Relativity theory and space-time structure, the standard Big Bang Model cosmology and what are the present-day evidences for it, what is the possible nature of Dark Matter and Dark Energy, are some of the topics that we will cover.  This non-technical presentation is intended for a general audience who has sometimes only wondered about our place in the Universe and what is its nature.
