Adding a Dynamic to Gravitation Reveals How Extra Gravity Halos are Projected from Galactic Cores*

It is unfortunate that the term dark matter was used to describe the extra gravity observed in galaxy clusters. The name presupposes a material answer, but the only thing actually observed is an Extra Gravity Halo (EGH). The mysterious source of this extra gravity remains unresolved. Or does it?

A new theory, sets GR in motion, predicting an ongoing space-time contraction within a gravitational field. Unlike Hubble expansion, this contraction field is non linear with distance from the source and projects more strongly with the increasing amount of concentrated matter generating the field. No assumed additional mass is needed to boost the orbital velocity of stars around a galactic core. The contraction field augments the acceleration of gravity to achieve galaxy rotation curves consistent with observation.

Dark matter is not a particle. EGHs are the result of relativity, and are an integral part of gravitation. The contraction field acts to scale up gravity. The scale factor, which falls easily from the math, has exactly the right mathematical shape to replicate assumed dark matter distributions. Not only do these contraction fields explain galaxy rotation curves, they also explain the Bullet Cluster, and Ultra Diffuse galaxies which have either a very strong EGH or none at all.
