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.

What is this theory of relativity and why is it so important? The mathematics of it are too much for most of us, but we can get some notion of it by a familiar illustration. A discussion of the more intelligible features of the theory of relativity.

Aimed at people who do not know enough physics to understand what Einstein did and why it was so important. The course presents just enough of Einstein's physics to give students an independent sense of what he achieved and what he did not achieve.

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.
