The energy is in the swirling, and not in the orbit of stars around
the galaxy nucleus. That uncovers dark energy and why the
galaxy doesn´t fly apart, as swirling builds binding forces.
A hurricane runs off its own energy, and this binding which
compresses the system is needed to explain the missing
invisible mass energies or inertial energies. As a large volume
of mass forms in the environment, it gains rotational momentum
and inertial energies generate currents and a central eye formation.

Its hard to think outside the box, that stars do not just orbit around
the galaxy´s nucleus but abide to swirling energies which build
up as a large volume of mass in the environment begins rotating.
