We're all gonna di-i-i-i-e!

Likely there is no connection. The thing that the magnetic fields protect us from is not radiation, actually, but charged particles, the so-called solar wind. Because of the Earth's magnetic field, these particles go around the planet, forming the Van Allen radiation belts. If the field collapsed, the belts would collapse, and that particle flux would impinge on the atmosphere. I don't know how much of the flux would make it to ground level. Likely very little would hit us directly, but it would play merry hell with the upper atmosphere and the weather.

This sort of thing (along with big-honking-asteroids) is a good reason for us to stop keeping all of humanity's eggs in a single planetary basket. On the other hand, this is a threat with a timescale of centuries, and humanity is currently facing threats with a timescale of years and decades. We really ought to focus our attention on those for the time being.>

In the theme of "beliefnet," I ask a simple question- Is there a God? If so, is God involved in maintaining the universe?

My opinion is that we have a very anthropocentric universe. We live as if humanity is all there is. If the world goes well, we take the credit. If things go poorly, we take (or assign) the blame. And, we assume we have the current knowledge to understand the complex life cycle of a massive planetary system, with all its geological and atmospheric systems.

What if there is a God who is active in the universe? Can't we trust the Creator to provide a safe habitat for us?

Just a thought.

(And no, I am not advocating waste or abuse of natural resources. Just think maybe we overestimate our knowledge and impact).>
