• TITLE: A Model of the Universe that Can Explain Dark Matter, Dark Energy, and the Fourth Space Dimension

  KEYWORDS: Universe, Dark Matter, Dark Energy, Gravity, Fourth Space Dimension

  ABSTRACT: This paper explains how a model of the universe can be constructed by incorporating time and space into geometry in a unique way to produce a 4-space dimension/1-time dimension model. The model can then show how dark matter can be the gravity that is produced by real matter that exists throughout our entire universe. The model can also show how dark energy is not an increase in energy that is causing the accelerated expansion of the universe, but is an accelerating decrease in matter throughout the universe as the stars and galaxies in the universe continue to convert matter into energy during their life cycles. And then the model can show how a fourth space dimension must exist in our universe to locate a point in space.
