What is (the) Matter?,other leitmotif throughout the book. Therefore, we start in this chapter by explaining why we can make the assumption that matter is made of waves. This is based on concepts from quantum mechanics and quantum field theory, but we keep it simple. We also explain how waves can contain and transport en

The Equivalence Principle, and gravitational mass and why is it not trivial that they are equal? Eötvös’s experiment shows us that they are equal. We discuss the equivalence principle using a variety of formulations and perspectives, such as locality and a comparison with other forces. We discuss how the bending of light in

A Journey to the Centre of a Black Hole,event horizon. We use different coordinate systems to differentiate between the view of a spaceship falling in and the view of a safe-distance observer. We show how it is possible for the time axis to become space-like and the radial axis to become time-like beyond the horizon. We discuss the possib
