Dark Matter

Dark matter is proposed as a hypothetical form of matter thought to account for approximately 85% of the matter in the universe. Apparent galactic rotation anomaly necessitated additional matter in galaxy to sustain its observed spin speed. Since no additional real matter could be observed, imaginary dark matter was invented to provide suitable explanation to galactic rotation anomaly. As dark matter is not defined, it is assigned different meanings in different theories. Galactic rotation anomaly is an apparent phenomenon caused by assigning reality to apparent planetary orbital paths around central bodies. Refer: http://viXra.org/abs/1403.0972
