  • RE: solar grand minimum influence on increased asteroid strikes?

    Everything I have read about a grand solar minimum seems to denote that less solar radiation means more cosmic influence, ie cosmic radiation, asteroid strikes, not to mention more potential for polar shifts and a weakened magnetosphere with increased gravitational influence from nearby bodies leading to more seismicity and volcanic activity, duh which we are seeing. I saw the biggest meteor of my life flying low overhead on the east coast of Hawaii Island on December 4th just months after my neighborhood was ravaged by lava. The question is, has anyone investigated whether there was a solar grand minimum taking place during the Chicxulub event or any other period of increased asteroid strikes? There seems to be a larger picture.
