Dark Matter - A Hypothetical Reality

Friday, March 21, 2014 Posted by Arun Vishwakarma , , No comments


Dark matter is that type of matter which is present everywhere in the Universe. It is hypothesized in cosmology for those accounts which are the direct effect of mass but no such mass can be seen. It cannot be seen with naked eyes or using telescopes, it neither emits radiation nor absorbs it. It is hypothesized to be non reactant to radiations. Much like black holes its presence can only be visualized by observing the surrounding effects due to its presence i.e. gravitational effects on visible matter, radiation and on the large scale universe.

It was firstly hypothesized by Jan Oort (a pioneer in Radio Astronomy) as the discrepancies in the mass of the large objects (galaxy, etc..) determined by their gravitational effects and the mass calculated by the visible objects (stars, planets, etc..).

Hello! There

This site belongs to Arun Vishwakarma and is the result of his own observations and analysis. This site doesn't uses any copyright material and if so then the acknowledgements were given as and when necessary. All the names and the core theories that are mentioned in any of the post is taken from different sources viz. Wikipedia, Google, etc. and except that the rest of the hypothesis and proposed theories are my own. All the concepts that are given in the posts are the brainchild of Arun and it is in no way criticize or prove other theories wrong rather it tries to define them using new concepts and provides new ideas to rethink them.
