Thanks for the information and I defer to your knowledge on the complexity of fusion. Consider the following proposition. Following the big bang, elements were distributed like shotgun pellets around the universe. Instead of having matter distributed evenly, higher concentrations would cluster around where stars would be formed. As the density of matter would reach a particular point, fusion would initiate and matter would be pushed away from the center point. Naturally there would be a push/pull (explosive pressure vs gravity) with heavier elements being found closer towards the sun (eg planet Mercury) and the lighter elements (eg Oort Cloud) found further away. Planets would be formed as a result of orbital clearing... all the dust in a path would be gathered by the gravitational pull of each planet.

I think that describes how our solar system was created. Now an additional speculation describes another aspect of what happens.

Cosmic rays are the atomic nuclei of hydrogen, helium and larger molecules that have been stripped of their electrons. They have been generated from galactic events such as supernova and quasars, and travel throughout the universe at almost the speed of light.

Add to this the nature of waves. A single wave from a single source is just a blip. Ordinarily the pressure of our solar wind is sufficient to deflect these atomic nuclei from both the sun and earth. Even a wave from two different sources wouldn't be a problem. Because of the principle of superposition the additive nature would occur. This means for the a period of time the amount of positive waves will combine into a megawave etc. I think that this leads to a chicken - egg / correlation- causation situation. Do solar minimums occur because of increased cosmic wave activity or does earth experience increase cosmic wave activity because of solar minimums (or both).

Studies have shown the Earth’s magnetic field, which acts as the second line of defense against cosmic rays, as well as being a shield against the solar wind, has been steadily weakening throughout the 20th century. Since the year 2000, however, the weakening has dramatically increased as illustrated in the following image provided by Davidson in his Earth Catastrophe Cycle series.

In part 2 of this series of articles investigating issues raised by Ben Davidson in his Earth Catastrophe Cycle video series, I discussed a CIA document authored by a geologist, Chan Thomas, that was only declassified in 2013. Thomas hypothesized that the inner core of the Earth, behaves just like a star in terms of emitting plasma or “neutral matter” in periodic bursts every few thousand years into the outer core, thereby triggering both magnetic and geophysical pole shifts.

I think the implication is that because of the solar minimums, the earth's magnetic protection is reduced which allows an increase in cosmic waves hitting Earth directly. I assume that having less solar activity has the paradoxical effect of increasing Earth's inner core activity (presumably increasing turmoil on the surface as well).

While on Earth, it is understandable that the beads could be formed through volcanic action. By extrapolation it might be assumed that this was the case on the moon. The flaw in this conjecture is that it would assume a fairly recent history of volcanic eruptions because the beads are readily found on the surface. Most traces of volcanoes went extinct over a billion years ago, (with the exception of pit craters like Ina). Part of the concern has to do with the shape of some of them:

I believe the assumption that some scientists who don't follow the volcanic model is that during periods of solar minima that it is a lead up to a special type of mass ejecta.

Instead of a single column of cme a wave of dust and particles are pushed out from the surface of the sun. The explanation for this is described as a micronova. Some of this debris hits the moon in the form of the beads. The rotation of the some of those beads at 5000 revs per second is due to this ejection (the conjecture is that volcanic action would not be sufficient to create this speed). A corollary of this ejection is that masses also strike the Earth causing massive destruction every 12000 years.
