It is assumed that the space(time) between all H-H knots is polarized with a quantum gravity- and electric effect on all matter in between the knots, resulting in a sort of gas-dust sweeping pressure cooker effect for star formation.

Curious tilt of the Sun traced to undiscovered planet?
Or the Herbig Haro remnant black hole system as Quantum FFF Theory predict.
All of the planets orbit in a flat plane with respect to the Sun, roughly within a couple degrees of each other.
That plane, however, rotates at a six-degree tilt with respect to the Sun giving the appearance that the Sun itself is cocked off at an angle.
Until now, no one had found a compelling explanation to produce such an effect.
"It's such a deep-rooted mystery and so difficult to explain that people just don't talk about it," says Brown,
the Richard and Barbara Rosenberg Professor of Planetary Astronomy.
Stars and Galaxies show equal spiral systems with 2x or 4x or more arms.
