Concepts of Dark Energy and Dark Matter: The Understanding and Calculation of ‘Dark Energy and Dark Matter’
Date Written: January 10, 2014
Mounting observational data collected during the last decades have provided growing evidence that the vast majority of the universe comprises two “dark” components, a mysterious, collisionless dark matter that holds galaxies together and even more mysterious, almost uniform dark energy component with negative isotropic pressure that produces cosmic acceleration. Together, these components capture around 96% of the present day cosmic energy budget. Dark energy is responsible for around 74% while dark matter captures almost a quarter, making it six times more abundant than visible matter. The visible matter is a very minor component in the universe since it captures around 4% of the universe. So far, dark matter and dark energy are inferred from their cosmic dynamic effects. Efforts to explain their makeup and interaction physics, however, have not been fruitful. This research also explorers the opinions and views of different professionals concerning the topic under investigation in order to identify their thoughts concerning dark energy and dark matter. The data gathered from secondary sources plus the thoughts of the various professionals will help in the design of the core fundamentals that should govern the design of a theory that would satisfactory explain the concepts of dark energy. The cosmological principle explains that the universe is highly isotropic and homogenous at super-galactic scales.
