The Big Bang theory has revolutionized our understanding of how the Universe was formed. It presents the scientific proof that shows how the Universe expanded from an infinitely small point around 13.7 billion years ago.

In this course the learner will discover how scientists calculated when the Big Bang happened and how the Universe expanded after the Big Bang. The formation of the first atoms is discussed and how they are responsible for the cosmic background radiation that is found throughout the Universe.

This course will be of great interest to students of astronomy and physics and to all learners who would like to learn more about the Big Bang theory and what it has to say about the formation of the Universe.

This course was interesting and enjoyable. Cosmic theories to muse over were not overly simple nor too complex. Thank you.
