Why do people accept dark matter and energy so easily?
But more recently, Kenneth Nicholson published a new method using Newton's law of gravitation to explain how the existing mass distribution of a galaxy without dark matter is sufficient to account for the rotation velocity profile. The method divides the galaxy into a series of rings subdivided into constant density segments. Each segment will cause an acceleration on a test mass at a given radius. The total a acceleration at a given radius by the interactions of the mass in the rings with their
appropriate densities is then calculated. The method shows that galactic rotation naturally deviates from the virial theorem and flat the rotation profiles come out spontaneously without further assumptions such as dark matter or MOND (source: https://arxiv.org/ftp/astro-ph/papers/0309/0309762.pdf)
Gallo and Feng also published "Galactic Rotation Described by a Thin-Disk Gravitational Model without Dark Matter."
Large Hadron collider hasn't provided any evidence either. It seems like there are too many hypothetical entities in this model -- dark matter, dark energy, inflation so why do scientists insist upon its existence? Does the model need revisions or an entirely new approach?
What do you guys think?
