What is Physics?

Why is the sky blue? Why do black holes exist, and what causes them? What's the most likely explanation as to how the pyramids were built? Physics describes the real magic of the universe. While other sciences explain how, physics is all about the "why.” It focuses on some of the most fundamental questions about our physical universe. Physics teaches you a method for approaching the unfamiliar and asking questions that get to the heart of what is unknown and how to make it recognized.
