Accelerating Universe: Theory versus Experiment
by Moshe Carmeli
Publisher: arXiv 2002
Number of pages: 43
We present gravitation as a theory in which the coordinates are distances and velocities between galaxies. We show that there are three possibilities for the Universe to expand: decelerating, constant and accelerating, and it is shown that the Universe is now in the latter phase.

This book examines the evolution of the principle of relativity in its classical, special, and general incarnations, with the aim of showing how it has repeatedly inspired advances in our understanding of the physical world.

This is a textbook on theories of special and general relativity. It is assumed that the reader has an understanding of mathematics through calculus and partial differential equations. The relevant tensor calculus is presented throughout as needed.

How better to learn the Special Theory of Relativity and the General Theory of Relativity than directly from their creator, Albert Einstein himself? Einstein describes the theories that made him famous, illuminating his case with numerous examples.
by Albert Einstein - Princeton University Press
A condensed unified presentation intended for one who has already digested the mechanics of tensor theory and physical basis of relativity. Einstein's little book serves as an excellent tying-together of loose ends and as a survey of the subject.
