Inertia and Gravity,y the same way, when not hampered by air resistance or the like. In other words: All matter . in the same way to gravity. This is called the equivalence principle. Using this principle we can observe if and how space-time is bending around us.

Solving the Einstein Equation of Gravity,he ball, starting from a far-away point. Here we determine how fast this test-mass will free-fall. This enables us to summarize how space-time is bending around a ball-like mass, by writing the Schwarzschild metric in plain language. We also will see how the classical Newton law of gravity fits in.

Book 20131st editional background. However, complicated calculations are replaced with figures and thought experiments, the text being formulated in such a way that the reader will be able to understand the gist intuitively. The first part of the book focuses on the essentials of special relativity. Explanations are pr
