It was premature of me to post all that, but, when I think of the sun's cycles, I think of the Heliopsphere/pause.

[Those dusty arms of the galaxy might harbor alot of rogue comets, just floating out in space, waiting to get in the way of Earth. They would be equivalent to non-periodic comets: they're massive, you don't see them coming, they are moving fast all the way in, you've got a few months to react, and you don't get a second chance]

It's not the dusty arms of the galaxy that I'm so worried about, again that worry IS premature since we won't be colliding into the Aquila Rift anytime soon. When that happens, the calm ISM(Interstellar Medium) we've been accustomed to will change in temps, gqas and particles and it will most likely send comets from 'our own' Oort cloud towards the inner planets. It's those small bodies within our solar system that will create the first havoc. We have these NEOs to worry about first (along with hurricanes, volcanoes, earthquakes, sun's tantrums).
