Abstract This paper presents a new theory of the universe which updates the Big Bang Theory, and explains more of the phenomena that have been observed over the past 120 years.

INTRODUCTION

Since the 1880's, scientists have observed that light coming from distant stars has a red shift, indicating that those stars are moving away from us at high speeds. In the 1920's George Gamow proposed the Big Bang Theory, that the universe was created by a huge explosion, and that all the matter in the universe is still flying away from that explosion at enormous speeds.

The Big Bang Theory explains why stars in every direction show this red shift. The theory assumed that the Earth is located close to the gravitational centre of the universe, which is the presumed site of the Big Bang. So objects speeding away from explosion will also be speeding away from Earth at roughly the same speed.

There are, however, several things that the Big Bang Theory does not explain, such as the distribution of matter in the universe, pulsars, the apparent lack of anti-matter, the lack of sufficient mass to hold galaxies together, the seeming acceleration in the rate the universe is expanding, and the discovery of objects that are apparently older than the Big Bang. The purpose of the paper is to present a more comprehensive theory of the universe which explains all of these observations.

HOW BIG, HOW OLD?

The newest telescopes have allowed us to glimpse galactic clusters more than 13 billion light years from earth. The apparent distance of such objects is one of the primary indicators of the age of the universe. The universe must be at least as old as the amount of time it took light from these objects to reach us.

Objects that are very far away are receding from us at extremely high speeds. This causes the light from the objects to shift in wavelength. Light of a given wavelength will appear stretched out, that is, the wavelength will be longer. This lengthening is called...
