Embark on a cosmic journey through a captivating lecture that explores the birth of the universe. Delve into the mysteries of the cosmic microwave background (CMB) and its role in understanding the primordial universe. Discover how observational techniques have advanced to create exquisite images of the CMB, allowing for precise comparisons with cosmological models. Explore the standard cosmological model, a comprehensive framework that combines CMB observations with other cosmic probes. Learn about the expanding universe, the concept of the "Hubble Patch," and how telescopes function as time machines due to the finite speed of light. Investigate the measurements at the heart of the standard model, including angular power spectra and model parameters. Examine frontier topics such as gravitational waves and their potential origins in the early universe. Gain insights into recent results and ongoing projects like the Simons Observatory. Conclude with a Q&A session to further explore this fascinating subject.

Introduction
Observing the Birth of the Universe
How Big is the Universe?
Sloan Digital Sky Survey main galaxy survey
From Hubble
The Universe is Expanding
The Universe is Infinite!!. We live in a "Hubble Patch"
Because the Speed of Light is Finite, Telescopes Are Like Time Macines
Now Add The Expansion
The Standard Model of Cosmology
Sloan Digital Sky Survey
How Do We Measure the CMB?
The Measurements at the Heart of the Standard Model
And at higher resolution...
"V Band", 61 GHz, 0.5 cm, from WMAP
Stacked hot spots
How do we get hot and cold patches?
Cosmic Paleontology
Angular Power Spectrum
Parameters of the Model
The model raises a lot of questions!
The Abbreviated Standard Cosmological Model
The frontier: are there other elements of the model?
What is a gravitational wave?
LIGO discovered two inspiraling blackoles that emitted gravitational waves as they coalesced
We're searching for gravitational waves produced from the extraordinary densities at the birth of the universe.
