Dear YuvaVeers!
Hariji did a presentation on the creation of the universe which probably piqued our interest in knowing where the universe came from. Well, Lawrence Krauss here did a similar presentation at the Atheist Alliance Conference this year in the US. The lecture below does not go in a linear fashion but seeks to explain various concepts associated with cosmology which will make it easier for you to understand the other books which you may read. In this lecture Krauss covers the beginning, current state and the end of the universe. I found this and another lectures during the conference extremely enlightening and I hope you would too. So I'll be posting them up regularly for your viewing pleasure.
I found this video from an article at the Richard Dawkins Foundation website.
