Module 14: Big Bang Cosmology: the Origin and Fate of the Universe

Supplements and Credits

Supplement the videos with "OpenStax Astronomy"

01: Cosmic Homogeneity and Isotropy

02: The Hot Big Bang

03: Why Does Cosmic Expansion Cause Redshift?

Frequently, people don't understand why expansion means that light gets redshifted. Here I try to link the two ideas. I hope it helps!

04: The Cosmic Microwave Background

The Cosmic Microwave Background is one of the most important discoveries in all of science.

05: The First Three Minutes of the Universe

06: Large Scale Structure Formation

Large-scale structure formation in the universe is the final pillar in the Hot Big Bang Standard Model. We want to know how galaxy clusters formed, how dark matter came to be where it is. Also, we learn why galaxy cluste[rs have so much hot gas, and how the absorption features in distant quasars came to be. We also see how the dark matter distribution can be mapped by its effect on galaxy's light and on the shape of clusters too. We also see how the Cosmic Microwave Background plays a central role in it all.

07: The Inflationary Epoch

The Inflationary Epoch solves a number of problems associated with the Standard Big Bang model. It also raises some wild questions about the nature of the origin of the cosmos.

08: The Ultimate Fate of the Universe

The discovery of Dark Energy in 1998 by two teams helped us learn what will happen at the end of the Universe.
