Preface

Amidst the boundless, infinite Universe, man and his world, is but just a mere speck of physical insignificance. But man's imagination is infinite and boundless; and those greats of our race, who have put their imagination, intuition and deduction to harmonious use, have come up with amazing facts of our Universe and great theories to account for the observation.

In the following account two of the greatest scientific discoveries of our time, that is, the discovery of the Expanding Universe and the Big Bang theory of the origin of the Universe are presented with an account of the observational and theoretical methods employed in the discovery.
