This course begins with an introduction to the Big Bang theory which states that the universe started with a small singularity and inflated over the next 13.8 billion years to the cosmos that we know today. You will study the Radius of Observable Universe which is a spherical region of the universe made up of all matter that can be observed from Earth or its space-based telescopes and exploratory probes.
You will then look into the Red Shift Phenomenon wherein electromagnetic radiation from an object goes through an increase in wavelength. This course will also discuss the Cosmic Background Radiation. You will study the Hubble's Law which states that the distance to a given galaxy is proportional to the recessional velocity as measured by the Doppler redshift. You will also delve into the Cosmic Inflation Theory as observed by astrophysicist Alan Guth.
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. Upon the completion of this course, you will gain better insight into when the Big Bang happened, how the Universe expanded after the Big Bang, and how the age of the Universe is estimated. Check out this course and learn more about the formation of the Universe.
