1. In Current Science, dark matter is a hypothesized unknown form of matter (with gravitational mass), that cannot be seen by telescopes because it does not emit, absorb, or scatter any radiation. This means dark matter is transparent to photons of any energy. Dark matter is provided as an explanation why the rotation speed of stars around the galaxy beyond a certain distance does not change with increasing distance from the center as would be required by the inverse square law of gravitational force. Dark matter is also provided as an explanation why galactic clusters remain bound together as they do not appear to have sufficient ordinary matter (stars, gas and dust) to achieve gravitational stability. Dark matter is claimed to contain 83 % of the total mass of the universe, and 23 % of the total mass/energy of the universe. Only 4 % of the total mass/energy of the universe is ordinary matter.
2. In Neu Theory, dark matter is not required because:
- The uniform orbital speed of stars in galaxies is caused by a hyper-field projection into space from the electric supercell core (black hole) g-rising at the speed of light. The hyper-field effect is in addition to the normal spinfield effect with g-rise at less than the speed of light. Neu Theory can make a prediction that orbiting satellites around smaller electric supercells (black holes) in a galaxy will also maintain a uniform orbital speed that is proportional the mass of the core. This may be possible to verify with an actual experiment.
- Galaxy cluster stability is maintained by individual galaxy g-rise/spinfields that are pushing each other apart, and at the same time are also being pushed together by the g-rise acceleration floor of the cosmos as a whole until an equilibrium state is reached.
