About Dark Energy and Dark Matter: A Simple Explanation

ABOUT DARK ENERGY AND DARK MATTER - A SIMPLE EXPLANATION This book tries to provide a simple explanation of dark energy and dark matter. And, what they might be. In the process, we will try to explain the following: The types of particles that constitute dark energy, as well as, and the kind of particle that constitutes dark matter. The connection that exists between the most basic dark energy particles and the invariance of the speed of light. The connection that exists between dark matter particles and the gravitational force. It concludes on the possibility that both types of particles: dark matter and gravitons could be the same. Finally, and based on the properties of the particles described, we try to give an explanation about the change on the expansion velocity of the universe.
