About This Chapter
Origins of the Universe - Chapter Summary
From the Big Bang Theory to continuing expansion, this chapter will cover facts about how the universe was formed and the ongoing changes it is experiencing. You will study information about photons, cosmic radiation, developmental stages of the universe and more. After completing your review of this chapter, you should be able to do the following:
- Relate facts about the Big Bang Theory and the timeline of the universe
- Explain how the universe is expanding and what the universe might look like in the future
- Present evidence of the Big Bang Theory
- Describe the formation of photons, deuterons, positrons and other matter following the Big Bang
- Provide details about the universe's four stages of development
- Discuss dark energy in the universe
Our experienced instructors will guide you through this material using simple terms, illustrations and examples to make it easier to study and retain this information. Review lessons as often as you'd like whenever you'd like, as videos are available 24/7 on any device. Self-assessment quizzes in each lesson help you determine how much you have learned and whether you are ready to move on to the next topic.
1. Origins of the Universe: The Big Bang and Expanding & Contracting Universes
Students will learn the origins of the universe, the Big Bang theory, the timeline of the universe, how the universe is still expanding to this day, and what astronomers expect the universe to look like in the future.
2. 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.
3. Photons, Particle Soup & Nucleosynthesis
This lesson will explore what happened in the fractions of a second and minutes after the Big Bang occurred. You'll learn about matter, antimatter, photons, deuterons, positrons, and a lot more!
4. The Evolution of the Early Universe
This lesson will describe four important stages of development in the early universe, the radiation era, recombination (decoupling) epoch, the dark age, and reionization era.
5. The Acceleration of the Universe
The acceleration of our universe is driven by a mysterious dark energy, which can take more than one form. This dark energy helps to explain why our universe is flat.
