The moment of creation

the long version

Few questions grip the mind more forcefully than those about the creation of the universe, and since the discoveries of the 1920s it has been a primary goal of physicists to trace the history of the universe back to "where it all came from" the moment of creation in the Big Ban. This is the up-to-date story of the enormous growth in knowledge of the early universe and the important discoveries about that titanic explosion that took place 15 billion years ago.
