I'll make a theory up. That "Supernova remnant cloud" that we are approaching is another solar system that has a dim star that isn't visible to the naked eye. They recently said that 80% of the universes stars could be that type, increasing the amount of stars by 80%.

It's that sun's heliosphere outside our own. The increase in meteorite/asteroid flybys would be by a disturbance of the Kuiper belt, possibly from planets in the outer orbit of the sun or the pressure from the heliosphere itself.

Earth changes/sun changes are a result of this second solar system exerting immeasurable pressure on our suns heliosphere.

All the nibiru and elenin bullshit is just a coincidence.
