Frequently Asked Questions about Physics and Astronomy
Explore the dynamics of matter and motion and the nature of planets, stars, moons, and asteroids, including astrophysics, the history of the universe, and applied and theoretical physics. Popular options include Astronomy: Exploring Time and Space and From the Big Bang to Dark Energy.
Introductory courses like How Things Work: An Introduction to Physics and Physics 101 - Energy and Momentum are great places to begin. You can learn online on a flexible schedule and build up to more advanced topics.
Yes. Try Astronomy: Exploring Time and Space, Astrobiology: Exploring Other Worlds, or Imagining Other Earths to get started.
Yes. When you complete a course, you’re eligible for a shareable electronic Course Certificate for a small fee, and completing a Specialization like Spacecraft Dynamics and Control earns a Specialization Certificate.
Absolutely—learn relativity with Understanding Einstein: The Special Theory of Relativity or rocket basics in Rocket Science for Everyone. For spacecraft motion and control, see Kinematics: Describing the Motions of Spacecraft and the Spacecraft Dynamics and Control Specialization.
For those interested in the intersection of data-driven astronomy and computer science, topics that explore implementing large algorithms and working with large datasets can help you discover ways to manage your data. Topics that explore the Big Bang theory will ask learners to consider where we come from and where we're headed. Advanced learners who are interested in spacecraft may consider topics related to the control of nonlinear attitude, kinetics, and spacecraft motion. Topics explaining nuclear reactor physics are perfect for engineers or those interested in neutron transport theory.
Learners often choose Understanding Einstein: The Special Theory of Relativity, From the Big Bang to Dark Energy, and Rocket Science for Everyone. These courses are highlighted across our Most Popular and Top Rated collections.
Any level of learner can begin; a background in the natural sciences can help but isn’t required. Start with introductory courses and progress to specialized topics as you build confidence.
