About This Chapter
Origin, Observation & Evolution of the Universe - Chapter Summary
Our engaging chapter covers the evolution, origin and observation of the universe. In a series of helpful lessons, this chapter covers subjects such as dark matter, the Big Bang theory and cosmic inflation. After you complete these lessons, you should be able to:
- Provide an explanation and definition of the galaxy
- Discuss the theory and the energy associated with dark matter
- Detail the evidence for the Big Bang theory
- Explain how cosmic inflation addresses the flatness and horizon problems
- Give facts and an overview about optical telescopes
- Explore radio telescopes, including their parts and facts
- Describe telescopes and the electromagnetic spectrum
- Outline the basic principles of spectroscopy
Even the toughest topics are discernible when you have help from the interesting lessons and quizzes included here. Before shifting your attention to other subjects or taking an important exam, complete the lesson quizzes and chapter test to ensure you're ready to do so.

1. Galaxy: Definition & Explanation
Galaxies are collections of stars, dust, and gas rotating around super massive black holes. This lesson will cover the structures and types of galaxies, including spiral, elliptical, and irregular galaxies.
2. What is Dark Matter? - Theory & Energy
In this lesson, you will learn what dark matter is and the latest theories about the origin of dark matter. You will also learn about dark energy and find out if dark matter and dark energy are related to each other.
3. Evidence for the Big Bang Theory: Background Radiation, Red-Shift and Expansion
Discover what evidence exists to support the Big Bang theory of the birth of the universe. Learn how cosmic background radiation, the red shift of light and the ongoing expansion of the universe led scientists to believe that the universe was started with the Big Bang.
4. Cosmic Inflation: Solving the Flatness & Horizon Problems
The standard Big Bang theory doesn't explain everything in our universe, namely the horizon problem and flatness problems. This lesson will explain what does, inflation, and how so.
5. Optical Telescope: Facts & Overview
This lesson will explain what optical telescopes are, their history, how they work, and how they're used. We will also review the three types of telescopes, including the kinds of aberration (distortion) from which they can suffer. A short quiz will follow.
6. Radio Telescope: Definition, Parts & Facts
This lesson will explain what a radio telescope is, how radio telescopes work, the parts that make them up, what each of those parts does, and why radio telescopes are important.
7. Telescopes & the Electromagnetic Spectrum
This lesson will teach you about which forms of light can reach the ground and which cannot and how we overcome this problem. We'll go over the concept of seeing as well as why we send telescopes into space.
8. Basic Principles of Spectroscopy
Learn what spectroscopy is, how it works, and what it allows us to learn about the universe. Discover the various applications of spectroscopy and then see how much you learned.
